PERFORMANCE INDICATORS FOR TELECOMMUNICATIONS AND PRICE-CAP REGULATION
I INTRODUCTION
In October, 19
Guidelines for
things) requir
87, the Australian Government released its "Pollcy
, Government Business Enterprises" which (amongst other
,es those enterprises to develop, use and publish (in
their Annual Reports) financial and non-financial Performance
Indicators (PIS). However few details were given, particularly about
the nature and coverage of the non-financial PIS. In May 1988, in
announcing its new framework for regulating Australian
telecommunications services, the Government reiterated ~ t s requlrment
that, in their Annual Reports, Telecom and OTC " . . . give an account of performance against previously established goals, xncluding
financial and operational targets and the performance of comparable
telecommunications companies to the extent practicable . . . " (Minister for Transport and Communications, 1988 p.20). Agaln, few detalls as - to the type of PIS required were provided. Accordingly, the prlmary
purpose of this paper is to contribute to the task of identifying the - -
sort of operational PIS that should be required under the categories of financial, economy, efficiency, equity and effectiveness crlterla.
The Government announced that under the new regulatory framework a
new "Price-Cap" system for regulating telecommunicat~ons would be
instituted. Under this system. Telecom and OTC would be regulated by
a CPI-X formula which will act to limlt price increases to a rate
wh~ch is the difference between the movement in the Consumer Price
Index minus a predetermined allowance for expected cost/product~v~tv improvements. Thus, if the CPI is 7% and the "X" factor is set at 3 % . priceincreases for telecommunications services, on average,
wFuld be limited to a maximum of 4%.
Proponents of this system claim that it will protect consumers (from
excessive price increases) while maintaining incentives for increased efficiency. The "X" factor ensures that the telecommunications carriers' expected cost improvement is passed on to consumers by way of real price decreases. Carriers would be encouraged to do better than "X" since they can retain the increased earnings. Less focus on the problematical rate-of-return or financial targgt calculation
would be required and the system itself would simplify regulation azc
reduce the transactions costs involved.

Abstract
The Commonwealth Government's October 1987 Policy Guidelines for
Government Business Enterprises requires these enterprises to
develop, use and publish (in their Annual Reports) financial and
non-financial Performance Indicators (PIS). Few details were given,
paarticularly about the type of non-financial PIS to be used.
Accordingly, this paper sets out to identify appropriate PIS,
classifying them under Financial, Economy, Economic Efficiency,
Equity and Effectiveness criteria. Telecommunications is used as a
case study.
In May, 1988, as part of its Economic Statement, the Government
announced a new price-cap system for regulating telecommunications.
The paper explains that PIS for telecommunications will be of as
much, if not greater interest, under this new system. In addition,
the paper demonstrates that whilst price-cap regulation has merit, it
will also confront several problematical issues. Moreover, the paper
warns that if it results in attention being focussed on price and
productivity changes, price-cap regulatioin will fail to spotlight -
indeed, may distract attention from - crucial aspects of the performance of the telecommunications carriers, in particular dynamic
efficiency and "effectiveness" in terms of achieving policy and
strategic objectives. Drawing attention to these issues now will
help ensure that they are addressed when the detailed plans for
price-cap regulation are being drawn up. <
The paper concludes with a discussion of the preconditions requ~red
for the effective use of a system of PIS.

However, while the price-cap system does have merit, it also has its
problems. Moreover, if it results in attention being focussed on
price and productivity changes, price-cap regulation will fail to
spotlight crucial aspects of the performance of the
telecommunications suppliers - in particular dynamic efficiency and "effectivenesst in terms of achieving policy objectives. Thus
another purpose of this paper is to ventilate some of these problems
and deficiencies so that they can be addressed as the detailed plans
for the new system are drawn up.
The paper wlll show that performance indicators will continue to be
required under the new price-cap system. Indeed, slnce the effects
of the new system will be closely watched, there may well be
increased interest ln indicators of performance in a broad sense, le
beyond financial crlteria to include, in particular, dynamic
efficiency and broader aspects of effectiveness. At any rate, the
thrust of the new regulatory scheme is reportedly to move to a system
of results-oriented, post-decision-making evaluation of
telecommunications operations. This, too, will generate greater
interest in the sort of results that the performance indicators
proposed in thls paper wlll monitor. In addition, there are
prospects that under the new system the boards and management of
Telecom and OTC will also be more concerned wrth the sort of
performance indicators proposed in this paper, particularly slnce
several are directly related to aspects of the price-cap formula.
It should be made clear at this point that in advocating a wlder
range of PIS this paper does not In fact seek to increase the - constralnts on Telecom and OTC. On the contrary, in settlng out to
develop an improved system of PIS which facilitates performance
monltorlng, the paper seeks rather to reinforce the Government's
moves towards less interventionist, more results-oriented, regulation
of telecommunications. Clearly an effective resultslperf ormance
monitoring system is crucial if support and confidence in the
regulatory changes are to be sustained. Conversely
an ineffective performance monitoring system will generate pressures
for the regulatory pendulum to swing back towards greater
pre-decision making monitoring by Government. Accordingly it would
seem in the interests of the telecommunications carriers to support
the development of a system of PIS which does effectively monitor and
evaluate the important aspects of their performance. This should
help ensure that their own attention and efforts are appropriately
focussed.
However, the development of PIS should not be left solely to the
telcos. The experience with the development of PIS for the UK
Nationalised Industries suggests that a strong Government lead may be
necessary for satisfactory progress. Moreover, it should not be
surprising if, left to choose its own PIS without the close scrutiny
and involvement of the regulator/government, a public enterprise selects those which represent it most favourably or which are
susceptible to strategic misrepresentation. This paper will provide
examples of where this has occurred in the selection of some of the
PIS currently in use. Unfortunately the short term benefits of such
strategic behaviour might seem more obvious to a public enterprise
than the longer run benefits of an effective performance monitoring
system.
The Government's price-cap regulation announcement made special mention of "international comparisons" in assessing the performance of Australia' s telecommunications suppliers. Although they should be
treated judiciously, and although they frequently need substantial qualification, such international comparisons may be useful, particularly where there are no other producers within a country
which could provide a basis for llyardstick'' assessment of performance. Thus, in seeking performance indicators, this paper will pay special attention to those that may be used in making international comparisons.
The organisation of the paper is as follows. Following this introduction, Section I1 assessses the performance indicators presently published by Telecom and OTC in their Annual Reports, and proposes improvements by way of alternative and/or additional
(complementary) performance indicators categorised under Financial,
Economy, Efficiency, Equity and Effectiveness criteria. Then, Section I11 presents a flpostscriptv discussion (since much of this
paper had already been written when price-cap regulation was announced) of how the PIS proposed in Section 11 will be as, if not
more, relevant under price-cap regulation. Finally, Section IV
presents conclusions and recommendations including an indication of
some of the preconditions or tlenabling" factors for PIS to perform effectively(2).
I1 PERFORMANCE INDICATORS FOR TELECOMMUNICATIONS
Table 1 enables an overview of Section I1 by providing a list of the
major issues which will be discussed in 'the attempt to identify
appropriate performance indicators for telecommunications. We begin
by examining the financial PIS c'omrtionly used in the private sector,
such as the level of profits, rates-of-return on assets and equity
etc. However, as is broadly acknowledged, while comprising one part
of a system of PIS, such commercial/financial criteria alone do not
constitute an adequate set of PIS, particularly for public
enterprises. (See eg Report of the House of Representatives Standing
Committee on Transport, Communications and Infrastructure, 1987, especially Chapter 7.) Thus, performance evaluation needs to extend
beyond financial criteria, to encompass (at least) the following
components of performance: Economy, Economic Efficiency, Equity and Effectiveness. ( )

Telecom Australia, and OTC, have published PIS in their Annual Report
for several years. We proceed now to assess the adequacy of the PIS
which they publish, in order to identify alternative or additional
PIS which might be useful.
Table 2 presents a copy of pages 6 and 7 of Telecom's 1986/87 Annual
Report which sets out its performance indicators. And Tables 3 and 4
set out Telecom's PIS published in its "Service and Business Outlook"
document. OTC1s PIS are not listed in a similar way but are interspersed through its Annual Report. Thus we discuss them as
appropriate in the various sections of this paper.
1. Financial Performance Indicators and Targets
Telecom uses the ratio of profit to total assets before interest as a measure of its financial performance. ( ) The return for 1986/87 is
given as 10.6% in historical cost accounting terms as Table 5 shows.
OTC does not publish its rate-of-return figure, although figures
provided in its Annual Report allow it to be estimated. For 1986/87
OTC's rate of return figure was 17.9%. Telecom makes no comment
about how satisfactory its rate-of-return is as a measure of
performance. Nor is this achievement compared against a target level -
in Telecom's Annual Report, although its "Service and Business
Outlook" document (September, 1987, p 8) discloses the target level
to be 10.5-11.5% on average. No explanation is given as to why this
target is appropriate. Perhaps there is an implication that the rate
of 10.6% looks "respectablew and/or fair against the returns earned
by other large Australian companies in the private sector (which
averaged about 13% in 1983/84 [Reserve Bank of Australia, 1986, p 61). The point being made here is that, to be understood by external assessors, it should be explained why a particular performance target is appropriate and why achievement against that target is satisfactory or unsatisfacatory.
Although a GBE's financial performance should be assessed against a
pre-established target tailored to its own circumstances and obligations, comparison with overseas suppliers of telecommunications
services do offer some added perspective for assessment of Telecom's
and OTCts financial targets and rate-of-return figures. At any rate
the Government now specifically requires that such international
comparisons be made (see statement by the Minister of Transport and
Communications, 1988, p.185).
Table 6, reproduced from Ergas (19861, indicates the rate-of-return
ranking for telecommunications suppliers overseas for 1982/83. The
Table suggests that Telecom's (and OTC's) rates-of-return did rank
higher than most other telecommunications suppliers. However, since
the rate-of-return of most of these companies is regulated, ( 5 1 it
is arguable that these figures say more about what rate-of-return the
respective regulators have considered acceptable or "fair" than about
performance. Moreover, the ranking information contained in Table 6
provides less infomatiion than actual rate-of-return figures.
Table 7 enables a comparison of more recent rate-of-return data. The
figures suggest that earning8 by Australia's telecommunications
suppliers are roughly equal to or, in OTC's case, exceed the rates
earned by American companies. For Telecom, earnings appear to be
substantially less than British Telecom's rate of 20.0% in 1986/87 (which includes earnings by British Telecom International - OTCfs
British counterpart - since rate-of-return data for this division of British Telecom's operations is not published separately).
It should be noted that the figures in Table 7 offer a preliminary comparison only, since in order to improve comparability, adjustments may be necessary. As is well known, comparisons of profitability - particularly internationally - have to be treated warily. As Heald
(1988) warns:
"Comparisons of profitability run into chronic problems because of the scope for manipulation of the figures. write-offs of asset values can be subjected to different accounting treatment, with very thin lines between them. There are both U.K. and international standards on 'unusual' items which either alter or rephase reported profitability. Companies have substantial discretion as to whether items are treated as fexceptionalf (taken before profit is struck) or as 'extraordinary' (taken
after profit is struck). Moreover, the existence of large
reserves, sometimes built up through the application of
comprehensive inflation adjustments or of supplementary depreciation, opens up the possibility for charging write-offs
direct to reserves. Any confidence that auditors will insist
upon consistency would be seriously misplaced." ( p 29)
It should also be noted that, as reiterated by the Byatt Report
(1986), the rate-of-return estimate in historical cost terms does not indicate economic performance. This seems now to be increasingly
recognised. Thus the Victorian Government requires its public
enterprises to aim at achieving a real rate-of-return of 4 per cent,
and the Department of Finance (1987) has suggested that an
appropriate financial target for Commonwealth Government Business
Enterprises be set at 6% in real terms, ie based on current cost
accounting (CCA). Using this approach, the return on total assets
figure published by a GBE will be presented in real terms to allow
comparison against this 6% target. (An extended discussion on
setting financial targets for GBEs and inflation/CCA accounting is
contained in Xavier and Graham, 1987.)
Even if CCA reporting is required, the historical cost accounting
figures should also continue to be published since, despite their deficiencies they do have some usefulness, allowing trends
to be observed, as well as facilitating comparisons with enterprises
nationally and internationally which continue to use historical cost
estimates. The onus could then be placed on an enterprise which
scores poorly in terms of this indicator to explain its poor performance. In this way the performance indicator system would be
playing its proper role of drawing attention to problem areas and
"triggering' investigations and remedial action. Moreover, the
debate about the correct approach to CCA seems yet to be resolve,
and, in such circumstances, as experience in the UK suggests, CCA
might allow even more scope for subjectiveness and creative
accounting than historical cost accounting. Thus as Xavier and
Graham (1987) have shown, significantly varying real rates-of-return,
depending on which approach to CCA is used, are derivable for Telecom and OTC.

All this is not meant as argument against the use of CCA but rather
to point out that there is a pressing need for careful consideration
of the accounting principles used by Government Business
Enterprises. Moreover, particularly for telecommunications
suppliers which are experiencing dramatic technological change and
equipment obsolescence (e.g. as fibre-optic rapidly replaces copper
lines) there is a need'to reconsider appropriate depreciation
policies and practices. Without clearly specified, generally
accepted accounting principles, there will probably be more latitude
permitted for the use of different accounting practices than may be
acceptable for regulatory purposes. For such reasons, various
aspects of accounting issues have recently been the focus of much
attention by OFTEL and the FCC.
Since the appropriateness of current cost accounting for Government
Business Enterprises has been receiving considerable attention in
Australia, it is worth pointing out that the issue will not recede
under price-cap regulation. Indeed, OFTEL has on several occasions
called upon British Telecom to resume publishing the current cost
information it did when it was a nationalised industry. British
Telecom, having suspended its publication of current cost information
in its Annual Report, has resisted OFTEL's requests "because of the
uncertainties surrounding the preparation and interpretation of such
statementsw, ( p 13 of the 1987 BT Annual Report's Financial
Supplement). However, OFTEL has disclosed that some CCA information
is being supplied to it by British Telecom (OFTEL, 1988) and reports
(OFTEL, 1988b) that in its 1988 Annual Report, British Telecom has
published some CCA information.
On a broader front, the British Treasury has been endeavouring to
progress (with limited success) the implementation by British
Nationalised Industries of the CCA recommendations of the Byatt Committee report (Byatt, 1986). Edwards, Kay and Mayer (1987)
address Fisher and McGowanls (1983) arguments about the shortcomings
of accounting rates-or-return as a measure of economic performance
and extend the debate about CCA and the economic analysis of accounting profitability into the private sector.
Despite these efforts, some of the problems of measuring financial performance accurately may be difficult to resolve satisfactorily.
And the persistence of such problems will serve to sap confidence in
the usefulness of financial performance indicators. This is another
consideration favouring the move away from rate-of-return regulation
towards "price-cap" regulation, since (in principle) the latter reduces the regulatory focus on the level of profits and, therefore,
the dependence of regulators on the regulated firm's unbiased
assessment in providing correct measures of profit and
rate-of-return.
There is clearly good sense in British Telecom suggestion, (Wheatley,
1987), that to reduce the dependence on the rate-of-return on assets measure, additional, complementary, financial indicators could be
used:
" ~ t is useful, in this connection, to compare earnings indicators with those used in the U,S, in relation to privately owned
telephone companies, Here we find a list very similar to those
used in the U.K. - an inevitable result of the internationalisation of financial markets, In both cases the
interest is highly focused on the stability and quality of the earnings in relation to the shareholdersf investment. Why were none of these measures considered useful or necessary when
British Telecom was a public industry? Obviously some of them
only relate to the existence of share capital, but others could
well have been enquired into in order to discover the return actually being made on the taxpayer's investment in the company.
- - ---- - -
"The Treasury had clear ideas of what it was trying to achieve and expressed this in terms of a real rate of return on new investment. There were, however, long debates about how achievement might be measured and the relationship that existed between internal rates of return and accounting rates of return. capital markets have never tackled the question in this way and have concentrated much more on likely net revenues and cash flows. As an illustration of this, the 5% real rate of return on new investment, which was a Treasury objective, has been difficult to relate to the cost of capital or to the rate of
return obtaining in private industry." (pp 16-17)
Other Financial Criteria
Amongst the supplementary financial criteria worth considering are
the following suggested by British Telecom which are commonly applied
in the private sector, (Wheatley, 1987):

2. Economy
Telecom and OTC do not publish specific PIS which demonstrate economy
(cost minimisation practices) in the purchase of labour, capital and
other materials. There are many questions which such P I S could
assist in answering. Are wage levels for specific types of labour
higher in Telecom and OTC than in comparable industries? Is capital
borrowed at relatively-competitive rates? As interest rates fall in
Australia, how have costs been affected and with what potential for
prices to be reduced? Are some aspects of wages/costs rising much
faster than others? Are input costs implying that the appropriate . .. - quantities/qualities of inputs are being purchased? Is the input
price index changing as might be expected?
The usual focus on the scale of outputs of telecommunications may
obscure significant developments on the input side. As the telephone
and computer industries have converged from a technological
standpoint, the telephone industry has benefitted from highly
efficient outputs in the computer industry. Will the declining costs
of switching and transport input technologies show up in Telecom's
input cost index? In addition, as frequently observed, under rate-of-return regulation the telephone service business may have
incentives to "cost-pad", "gold plate" or over-invest, for example rn
computer and fibre optic investments (which, in due course, are
capable of producing long-term gains in output at extremely low
marginal costs). Moreover, telephone carriers might have an
additional incentive to engage in such "strategic waste" or
overcapacity in anticipation of future implementation of price-caps
or increased competition (since the existence of significant excess
--A -- capacity could-deb--patentid--competitors [Sappington, 19801). PIS which monitor input costs could help restrain such activities.
Finally a firm itself would no doubt be concerned to keep track of
trends in input costs since this provides essential information for
expense control. Being required to publish such information should
provide further lncentlves for improved performance In lnput cost
control.
Where significant decreases in input costs are enjoyed by tele-
communications suppliers, it is important that consumers benefit as
well. Requiring the telephone carriers to produce input cost PIS
will help ensure that this occurs.
3. Economic Efficiency
The concept of "economic efficiency" may be usefully explained - particularly for operational purposes - by a breakdown into:
(a) Allocative Efficiency
(b) Technical (including "X") Efficiency, and
(c) Dynamic Efficiency
(a) Allocative Efficiency
This is usually discussed in the theoretical literature in terms of
achieving the conditions for "Pareto-optimality". In non-technoical
terms, "allocative efficiency" is concerned with decisions regarding
the production of the "appropriate" quantity/quality of the
"appropriate" goods and services. More specifically, allocative
efficiency embraces "price efficiency" within firms as well as
efficiency in the allocation of factors among firms, of goods among
purchasers and the marginal cost/marginal valuation relationship. In
essence, in regard to telecommunications performance, allocative efficiency prescribes attention to the level of prices, the structure
of prices and the quality of services provided.
Level of Prices -
Telecom's 1986/87 Annual Report contains a graph showlng that the
average prlce level for its basic products has increased by 21.9%
over the flve years slnce 1981/82 (roughly 4.4% per annum),
slgnlficantly less than the 47.2% (about 9.4% per annum) increase I n
the CPI during the same period. (Note that this decllne In real
prrces of 5% per annum is a greater reduction than the 3% sought by
the CPI-3% prlce-cap formula applled to Britlsh Telecom.)
- 19 - -,
This is certainly welcome information, but how good is TeLecomfs performance here? If price increases have been low because Telecom's
rate-of-return is relatively low, or if the producer price index for Telecom's inputs had increased by less than 21.9% during the period, or if productivity improvements coupled with economies of scale and scope reduced real per unit costs by more than 5% per annum, Telecom might not have much to be proud of. Hence, to be more meaningful in regard to performance, discussion of Telecom's price level changes
should refer also to such comparisons rather than only to the CPI
movement.
What about the level of prices for Telecom's services when compared
with levels prevailing overseas? The implication in such a
comparison is that (other things constant) lower prices. reflect lower costs, and so greater efficiency. Table 8 sets out figures which indicate that in regard to the level of telecommunications prices for residential service, Telecom ranks fifth of the eleven countries
listed. Telecomfs approach of using the "number of working hours necessary to pay a telephone billw avoids the problem of exchange rate conversion. But it can-be challenged for other reasons. For example, it is arguable that the comparison should strictly be made on net earnings, not gross, to allow for differences in taxation, etc. The approach also tends to reflect overall differences in productivity rates rather than differences specific to telecommunications.
Consider also Table 9 which undertakes a similar task of ranking telecommunications price levels in different countries and, in addition, provides a useful breakdown between residential and business tariffs. It is presented here to demonstrate a commonly used alternative method of ranking; as a cross check on the ranking provided by Table 8; and to show how a company - in this case British Telecom - can experiment with different methods and "weightsw to find one which presents its performance most favourably. British Telecom, which ranked eighth on Telecom's method, ranked fifth on its own comparison. Australia's position slipped slightly from fifth to sixth place. Canada ranks ahead of Australia in both comparisons, indicating lower telecommunications prices. Of course selectively excluding or including countries to be compared against can also help to change a country's ranking. (McDowall, 1987, and Horton and
Donovan, 1987, provide detailed appraisals of British Telecom's and
other international price comparison approaches. A recent document
produced by Telecom discusses alternative approaches to international
price comparisons for telecomrnunicatiions services, see Telecom

But just how good is Telecom's performance here? Albon (1987 a)
reminds us that the lThours of work to purchase a standard package of
telecommunications services" measure is "tricky" and has to be used
with caution. For instance, it involves costing a given basket of
services in different countries, and the resulting rankings are
sensitive to the composition of the basket. Factors which might
complicate international comparisons are differences in
telecommunications products, service level and quality, marketing,
geography, topography, cross-subsidisation, rate structure, the call
pattern, etc. Nonetheless, on the basis of the figures in Table 8,
Albon points out that Canada ranks ahead of Australia, and suggests
that this is a noteworthy comparison in view of the significant
similarities in standard of living, population, density and
dispersion which exist between Canada and Australia. While Canada's
overall population, at about 25 million, is larger than Australia's
(approximately 16 million), that larger population is spread over an
area nearly a quarter larger again, so its density is almost the
same, The dispersion of population, with a major concentration in
the south-eastern corner and a smaller concentration in the
south-west, is also remarkably similar. Albon concludes by pointing
out that:
"Telecom has never answered the charge that it is
cost-inefficient relative to Canada, on its own measure, and has
not shown why Canada is different." (p 28)
Certainly, it would be instructive, and potentially constructive, for
Telecom to consider why Australian telecommunications seems to
perform less favourably than its Canadian counterpart on this
measure, Indeed, this presents an example of the way in which PIS
can act constructively to trigger investigations which could yield
information germane to effecting remedial improvements.
Looking only at the level of prices is, of course, being myopic. In Telecomts case, it should be pointed out that although its prices
were higher than its Canadian counterpart, so was its rate-of-return
on assets (see Table 6). More generally, while Telecom's prices were
in the middle range for the advanced economies, its profitability was
amongst the highest. Ergas (1986) has concluded from his study,
which includes such comparisons, that,
"Together, these criteria imply that the Australian
[telecommunicationsl network is at least not technically
inefficient (since it is achieving an above average return on
investment without having above average prices) and may in fact
be operating at levels of technical efficiency above the OECD
average, particularly when geographical constraints are taken . -
into account." ( p 2 5 )
Ergas' conclusion has been challenged by Albon (19871, but his
approach, which considers levels of prices jointly with rates of
return earned, is undoubtedly more appropriate than a consideration
of level of prices alone.
OTC's Price Level
OTC published its performance indicators in its Annual Report for
1986/87 in a way different to that of Telecom. The reduction in the
real level of prices is shown in a graph depicting a fall in the
average number of hours worked to pay for a 7 minute IDD call to the U.K. or U.S.A. The cost is shown as having declined from 1.4 hours of work in 1983, to less than 1 hour in 1987. Comparison with
telecommunications charges for other countries based on the same
approach would have also been useful but were not provided.
An example of such an international comparison is pnovided in The
1987 Annual Report of Singapore's telecommunications authority. The comparison which includes OTC, is reproduced as Table TO. Of course,
such a comparrson wrll change as exchange rates alter but is of lnterest nevertheless, particularly when a country's exchange rate 1 s
relatively stable, or when rates averaged over, say, one year, are
used.
According to Table 10, at the end of 1986, OTCfs charge per minute
for calls to Singapore was 2.33 Singapore dollars, fractionally
higher than Telecom Singapore's charge of 2.30 Singapore dollars for
calls to Australia. It should be noted, however, that this
comparison was made in 1986, after there had been a significant fall
in the value of the Australian dollar against the Singapore dollar
(which would have significantly reduced the cost of a call from
Australia in the comparison). If reliable, such comparisons might be seen to have important implications, not only for business
telecommunications expenses, but, for example, as a factor in a
country's ability to compete in attracting the regional headquarters
of multi-national companies to its shores. But, of course, as
mentioned earlier, doubts can quickly be raised about the reliability
of such comparisons. Nevertheless, they can be useful by placing the
onus on those who measure poorly, to explore and explain their
position. The information provided by such explanations could also
be useful to outside assessors of a company's performance.
Perhaps this 1s one reason why the Federal Communications Commlsslon
in the USA prepares and publishes International telephone prlce
comparlsons between the Unlted States and nlne other countrles - not at the moment lncludlng Australla. The prlces are glven for dlal
calls that orlglnate in the U.S.A. and termlnate rn the other nlne
countries, and the prxces for dlal calls that orlglnate rn the other
countrles and termlnate In the U.S.A. The prlces are stated I n
U.S. dollars per mlnute of use, beglnnlng with a one mlnute call and
endlng wlth a twelve mlnute call. The prlce comparlsons for 1987
reproduced In Table 11 Illustrate the method used and show that
prlces for dlal calls from the U.S.A. usually tend to be much lower
than the prlces for dlal calls from the other countrles to the Unlted
States. Moreover, the prxce differences tend to lncrease as the
length of the call Increases.
OTC should be required to undertake and publlsh a similar set of comparisons.
(ii) Structure of Prices
The structure of telecommunications prices is another important aspect influencing performance in regard to allocative efficiency.
Accordingly, the conclusion of one commentator's analysis (Albon,
1987) of Telecom's pricing structure, is pertinent to this study:
"One thing is certain. The present pricing structure is highly inefficient and cannot be justified on the basis of either major
approach (access charging or Ramsey) to optimal
telecommunications pricing." ( p 22)

Albon estimated that this form of pricing inefficiency results in a
welfare loss to the Australian community of about $250 million per
annum, based on 1985-86 figures (Albon, 1987 b, p 21). Yet neither
Telecom's Annual Report nor its Service and Business Outlook
publication, refer to performance indicators and targets in regard to
the structure of prices.
The broad problem is that access charges are far too low and usage
charges (for the most important services) are far too high. As Albon
concluded from his study:
"The fundamental imperative is to reduce charges on long-distance
calls and to retrieve the lost revenue through higher access
charges and the introduction of charges on unpriced services.
The reductions in deadweight losses. from lower STD charges could
be attained without any offsetting increase if access charges
were raised in a manner consistent with taxing surplus. Given -
the very low elasticities of demand for business and most
residential demand, the task should not be too difficult.
Lowering STD by raising tariffs on underpriced services reduces
deadweight losses at both ends." (p 21)
Evidently, Telecom is well aware of the importance of aligning prices
more closely with costs, as evidenced by Cutler's (1987)
acknowledgement that:
"Major realignments are also needed on the price side. Since
1981 Telecorn has actively sought to bring the balance between
local and STD charges more closely inta line with economic
rationality. Considerable progress has been achieved; but the outcome has been compromised by politically-imposed changes in
the size of local calling zones and by real or presumed
resistance to the timing of local calls.
"Looking to the future, I believe that three elements will be
vital if more rational price structures are to be put in place.
Firstly, to align charges more closely to costs, we need to
re-think the actual components and structure of charges. Second,
charges for different services (eg data and voice) should be
harmonised insofar as they involve substitutable facilities.
And, third, prices for dedicated services and interconnection
should reflect the full cost these impose on the network,
incluing in these costs the provision of redundancy and of
back-up capacity." (p 6 4 )
OTC, too, is well aware of the need for prices to reflect costs,
"OTC1s pricing policy is to alter prices to reflect cost
movements. This can result in price reductions for large scale
and automated services, such as IDD telephone, and increases for labour-intensive and smaller-volume services, such as telegram."
(1986/87 Annual Report, p 3 3 )
What performance indicators could be used in regard to monitoring
progress in relation to adjustments to the structure of prices?
Albon (1986) suggests an approach which would provide a means of
ascertaining progress and facilitating such monitoring:
"The appropriate way to.proceed would be to set a target date for
the completion of a rebalancing program that is based on the
desire to achieve allocative efficiency while retaining
justifiable and defined subsidies. All changes in tariffs would
then be steps towards this goal. Achievement of the goal would
also require some equipment changes (eg in regard to metering) so
that some co-ordination between those making pricing and
investment decisions would be necessary. Community obligations
would have to be clarified. This is a responsibility for the
Government." (p 22) , ,
If a programme of gradual rebalancing, with target dates specified,
existed, it would allow Telecom and OTC to report on, and for
external assessors to evaluate, progress made. Being required to
It is not yet possible to identify just how technically efficient
Telecom is. An approach which is commonly used is to define the
production frontier according to the practices of the most productive
firms in an industry and to measure the technical inefficiency of the
firm being studied in relation to this frontier. However the
requisite rigorous econometric and other research has just not been
done. Thus, for the present, we must base assessment of technical
efficiency on whatever available evidence can be assembled, such as
real unit cost reductions and productivity improvements.
Value-Added. This is sometimes used as an indicator of technical
efficiency. Both Telecom and OTC display their value-added estimates
proudly. As Table 2 shows, Telecom declares that its value-added was
55.2 billion, or 2.2% of GDP, and then proceeds to describe the
distribution of value-added to employees ( 5 4 . 2 % ) , to providers of
capital (22.1%), and for re-investment (23.7%).
OTC reports that its value-added increased from $213.9 million in
1985-86 to $262.7 million in 1986-7. The latter figure was divided
among employees (35.8%), payments to the Commonwealth Government
(32.2% comprising 15.2% for dividends and 17.1 for income tax), and
redeployed in the business (31.9%).
However, this presentation of value-added data provides far less
information about performance than, for example, the presentation in
Table 13 reproduced from Telecom Singapore's Annual Report for
1986/87. Trends in value-added per employee, per 5 employment costs,
and per $ of investment in fixed assets, etc., would be useful
performance indicators.
- . . - - . . -
Labour Productivity
his is another commonly used indicator of technical efficiency. In
Table 3, Telecom refers to "an improvement in labour productivity (number of access lines per employee) of about 7%, consistent with
our longer term average target of 5-7%." In addition, Telecom refers
to " . . . A reduction in direct operating expenses per access line in real terms of about 4%. This is consistent with our longer term average target of 2-4% reflecting significant improvements in
efficiency." -
report on progress in its Annual Report would ensure continuing
attention to improving the structure of prices. But there will
clearly be difficulties even in implementing the changes gradually.
For instance, as discussed more fully later, equity considerations
could be a constraint. And there is likely to be opposition from
some quarters. However, there would probably also be many
supporters, for example, metropolitan users who frequently use STD.
And with the prospect 'of increased competition, and/or as technology
makes bypass by major users more and more feasible (as it has in the
USA), the incentives for Telecom and OTC to persevere in effecting
changes are significant. This is because the changes advocated are
likely to be forced upon Telecom and OTC by competition which would,
in particular, affect the long-distance market. The changes that
Telecom and OTC make would reduce the attractiveness of presently
overpriced routes to potential competitors and, in any case, would
help render them more able to withstand competition that does emerge.
Moreover, it would reduce the incentives for bypass by major users.
(iii Quality of Service -
The quality of telecommunications services supplied by a carrier is
an important aspect of its performance. Where competition does
exist, attention to the quality of service will probably constitute a
major element of competition (as evidenced in the USA), since
consumers will make their decisions based on price-quality
characteristics. Eowever, where competition does not exist, there is
no such comparable pressure for suppliers to be as concerned over
quality. Indeed, there is concern in some quarters that quality
deterioration may even be seen to be a way of lowering costs so as to
improve "productivity* indicators or profits. (7)' Thus, in the Australian situation, quality of service indicators which facilitate
monitoring are required to simulate the pressures of competition on
quality of servlce improvements.
What are the aspects of telecommunications quality of service for
which performance indicators are required? Th.ese depend, of course,
on the service characteristics which both residential and business
customers consider important. And thus every effort should be made
to establish what these are, including questionnaire surveys and
personal interviews with large users.
While OTC does not, Telecom lists a range of quality of service
achievements and targets as shown in Table 4. However, some of these
targets could - and should - be expressed in more quantitative terms, as the examples provided by British Telecom demonstrate. Such a
quantitative expression of targets will facilitate measurement of
achievements against targets, allowing performance to be more
precisely assessed.
Repair Service
As an example, in regard to the task of fixing service faults,
Telecom expresses its measure of performance to be "customers
satisfied with fault repair response", with achievement in 1986/87
reported to be 75%, the target for 1987/88 being 75%, and the target
to be achieved by 1989/90 being 90%. By contrast, British Telecom's
repair service targets are more specific and verifiable:
"The standard we are working to in 1987/88 is that all faults
which interrupt service should be cleared within two working
days. During 1988/89 we shall be improving our performance so
that by March 1989, under the standard Repair Service covered by
our line rental charges, we shall be aiming to restore service to
business customers within half a day (5 working hours). For
residential customers, who pay a lower rental. for their lines and
are generally more dispersed, we shall aim to restore service
within one working day (9 working hours) or by later appointment
if the customer so desires.
"Minor faults which do not interrupt service, and initial
temporary repairs, should be rectified within 3 working days.
"By the end of this year we shall have in place arrangements
which will enable customers to report faults at any time - 24 hours a day, 7 days a week." (British Telecom, Quality of Service Report, October, 1987, p 1 )
Telecom's service targets for business customers are more
specifically stated. For example, Telecom offers "a premium service
based on negotiated contracts or fee for service for guaranteed
response within 2 hours or as required by the customer."
While such premium services to business customers are welcome, lt is
important to ensure that service to residential customers does not
deteriorate as a consequence. This reinforces the case for
publication of performance indicators which facilitate quality of
service monitoring for both residential and business customers.
Installation of Service
From Table 4, it may be seen that Telecom measures this aspect of
service quality in two ways:
. customers satisfied with telephone service installation commitment (with a target of 90% by 1989/90);
. new telephone services connected within 13 working days of application (with a target of 90% by 1989/90).
The first point worth making is that British Telecom's targets for
installation are to have orders completed in 6 days for business and
8 days for residential, although it notes that customers often glve
longer periods of notice so that the performance indicator based on
how quickly installation is completed could be misleading.
Recognising this, British Telecom now prefers to use an indicator
based on "appointments made, and appointments kept". It should be
noted that in the Performance Report contained in its 1985/86 Annual
Report, Telecom Australla also foreshadowed the use of such a - measure:
"Telecom is developing a new approach to customer service-based
on the concept of making commitments to customers at the time of
application for service and then measuring performance in terms
of success in meeting these commitments. The new commitment
working concept recognises the fundamental need to provide
service when the customer wants it and will lead to a substantial
improvement in the quality of service provided." (p 6)
However, this approach is not referred to again in Telecom's 1986/87
Annual Report. And it is not clear why not.
Operator Services
As Table 4 indicates, Telecom also has performance measures and
targets relating to the proportion of customers "satisfied" with
customer assistance services. This criterion seems rather vague with
performance difficult to verify. By contrast, British Telecom uses
more specific criteria upon which performance is more easily verified
and assessed:
"From April 1988, Directory Enquiry customers should increasingly
get through first time, and our aim is that operator calls for
whatever purpose should normally be answered within 15 seconds.
We shall be carrying out periodic checks, jointly with OFTEL, on
congestion in the Directory Enquiry service so that we can report
on this aspect of the service as well as on the time taken to
answer." (British Telecom, Quality of Service Report, October
1987, p 2)
Since it may assist in identifying performance targets for Telecom,
Table 12 reproduces British Telecom's recent Operator Enquiries
performance figures.

[Source: British Telecom. Quality of Service Report, Oct, 1987, p 21
Public Payphones
A notable omission from the range of Telecomrs quality of service indicators is one relating to public payphone serviceability. For
those in transit or those without a telephone at home, for example,
the proportion of payphones which are not "out of order" is an
important part of quality of service. To provide an example of the use of a performance indicator in this regard, British Telecom
reached an average public payphone serviceability across the U.K. of - 85% in September 1987, and announced a target of 90% serviceability
by March 1988. It has also stated that joint monthly studies with OFTEL would be carried out to ascertain success in achieving this
target. (British Telecom. 1987. p 2). Telecom should be required to publish performance achievements and targets for this aspect of its
service as well. to ensure that the quality of this important part of
the range of services it provides is not neglected. (8)
In concluding this section on quality of service, it is reiterated
that the discussion here has focussed on just a few examples of the
use of PIS in this regard. Since demand is sensitive not just to
price but to quality, it is in the interests of telecommunications
suppliers as well as their customers to ensure that strenuous efforts
to improve the quality of service in aspects valued by customers are
sustained. And the publication of appropriate PIS will help ensure
that this occurs. On competitive routes in the USA, competition is
being waged in terms of quality of service (particularly as an
oligopolistic price leadership structure emerges with MCI and US
Sprint maintaining their prices slightly below AT & T each time the
latter varies its prices). On currently non-competitive routes, the
Bell Operating Companies (BOCs) are concentrating significant
attention on quality of service perhaps at least partly in
preparation for when they are permitted to compete in other
telecommunications routes and services. In Canada, although there is
no competition on the basic telephone network, Bell Canada has made
customer service the major thrust of its corporate strategy. That
such efforts are not misplaced was made clear recently in the'^^ when large business users were strident in their complaints about the
quality of services provided them by British Telecom.
(b) Technical (including "X") Efficiency
Technical inefficiency occurs where a firm's output is less than its
maximum achievable output (on its production frontier) because factor
inputs are idle or combined in inappropriate proportions. This
aspect of economic efficiency is concerned with whether Telecom is
using the optimal mix of input, given factor prices, and is operating
on its production frontier or, at any rate, progressing towards least
cost production (taking into account the effort of its management and
other employees).
It is not yet possible to identify just how technically efficient
Telecom is. An approach which is commonly used is to define the
production frontier according to the practices of the most productive
firms in an industry and to measure the technical inefficiency of the
firm being studied in relation to this frontier. However the
requisite rigorous econometric and other research has just not been
done. Thus, for the present, we must base assessment of technical
efficiency on whatever available evidence can be assembled, such as
real unit cost reductions and productivity Improvements.
Value-Added. This is sometimes used as an indicator of technical
efficiency. Both Telecom and OTC display their value-added estimates
proudly. As Table 2 shows, Telecom declares that its value-added was
$5.2 billion, or 2.2% of GDP, and then proceeds to describe the distribution of value-added to employees (54.2%), to providers of
capital (22.1%), and for re-investment (23.7%).
OTC reports that its value-added increased from $213.9 million in
1985-86 to $262.7 million in 1986-7. The latter figure was divided
among employees (35.8%), payments to the Commonwealth Government
(32.2% comprising 15.2% for dividends and 17.1 for income tax), and
redeployed in the business (31.9%).
However, this presentation of value-added data provides far less
information about performance than, for example, the presentation in
Table 13 reproduced from Telecom Singapore's Annual Report for
1986/87. Trends in value-added per employee, per 5 employment costs,
and per $ of investment in fixed assets, etc., would be useful
performance indicators.
Labour Productivity
This is another commonly used indicator of technical efficiency. In Table 3, Telecom refers to "an improvement in labour productivity
(number of access lines per employee) of about 7%, consistent with
our longer term average target of 5-7%." In addition, Telecom refers to " . . . A reduction in direct operating expenses per access line in real terms of about 4%. This is consistent with our longer term
average target of 2-4% reflecting significant improvements in
efficiency." -

The sixth column of Table 14 allows the labour productivity statement
to be put into perspective. As the table shows, Telecom ranks the
lowest of all the countries shown in terms of lines per employee, both in 1974 and in 1985. Again, a noteworthy comparison.with
Australia's 69 lines per employee is Canada's 125. From Australia's
low level, appreciable improvements on this measure may not be
surprising. As Tomlinson (1986) points out, there is a well known
correlation between lines per employee and connections per 100 dwellings, with countries tending to move up a common track. Whilst
the improving trend in lines per employee is welcome, it will not
reveal much about whether or not Telecom's relative productivity performance has changed.

One can of course provide several reasons for Australia's low ranking
in terms of lines per employee, including geography and density.
Moreover, it is true that in any event, the figures are not strictly
comparable because of different sub-contracting practices (with some
countries subcontracting a greater number of workers, thus showing a
higher lines per (permanent) employee figure, different hours worked
per employee, different range of services provided, varying degree of
plant modernisation etc. Nevertheless, international comparisons
might be useful in indicating broad differences in performance and
relative shifts in such performance over time. Another reason for drawing attention to these figures is to indicate how figures can be used selectively and in best light as a performance indicator. Despite Telecomls low ranking here, it has, in fact, managed to use
the lines per employee situation to suggest strong productivity
performance. Of course, because of the considerable potential for
improvement, Telecom can confidently expect aspreciable improvements,
and has chosen to focus on the increase in lines per employee as a
performance indicator of productivity improvement.
Table 14 also indicates that despite a sharply growing number of main lines, Telecom was able to increase slightly--its-average revenue per main line. However, whilst for many countries operational
expenditure per main line fell, for Australia this increased from U.S.$ 236 to U.S.$ 264.
Another indication of operational perfmance is provided by Table 15
which indicates that operational expenditure per unit of traffic rose
in Australia, from U.S.$0.22 in 1974 to U.S.$0.28 in 1985, by contrast with falls for all other countries in the table (for which
the comparable data is available).
In concluding this section it is worth repeating that although broad relationships and trends in the figures can be revealing and useful if they trigger investigations by 'poor performers1, too much should not be made of the comparisons in themselves. As the OECD (1988) emphasises:
I1International comparisons need to be undertaken with caution in that differences in market structures, pricing and accounting procedures, employment policies, as well as relative degrees of
use of new switching and transmission technologies, can bias corn par is on^.^^ ( p 22)

Total Factor Productivity
Even an accurate labour productivity measure would, however, be only
a partial measure of productivity. Such a measure which focuses on a
single factor, labour, takes no account of factors such as:
. increased capital intensity;
. investment in Research and Development, which yields better technical processes
or better products;
. greater capacity utilisation; . -
. improvements in organisation; and - . use of a more skilled workforce;
all of which contribute to productivity growth.
Total factor productivity (TFP) measures which recognise the
contribution of these factors are no doubt preferable, but their
calculation is fraught with difficulties, eg. the presence.of scale
effects, the difficulties of measuring capital, the problems of
defining the (changing) product set, the problems of properly
segregating and measuring inputs, etc.
There have, nevertheless, been considerable overseas efforts to
estimate TFP for telecommunications. OFTEL (1988 refers to one estimate, by Foreman-Peck (19881, which suggests that Brltish
Telecom's trend rate of increase in total factor productivity lay between 1.6% and 2% during the period 1964/65 to 1980/81. But an
alternative set of figures, using different data derived by Pryke for
the period 1968-1978, and by Molyneux and Thompson (1987) for the
perlod -1-478-1985; gtves---a hrgheravq-e'Tigurebf 3% over the period
1968-1985 - though over the period 1978-1985, an increase of only one half per cent a year was found. Studies for both the U.S.A. and
~anada" ) suggest a rate of increase in productivity of over 3% a
year. Bell Canada claims to have achieved a TFP increase of over 6%
in 19886/87 (Annual Report, 1987). An estimate for West Germany
produced a figure of about 2 1/2 (two and one half) % . OFTEL
estimates that " . . . if past U.K. experience is the basis, the likely level of productivity increase seems to lie within the range of 2-3%
a year." (OFTEL, 1988, p 9) *
In the light of such estimates, de Ridder's (1986) disclosure that
" . . . preliminary estimates find Telecom's TFP growth in the nine
years to 1984/85 was nearly 7%'' (p8) is striking, particularly when
compared with the trend TFP growth for the Australian economy, of
1.4%. However, almost two years after this disclosure, Telecom could
not advise whether further work confirmed its 7% preliminary
estimate. As stated earlier, estimating Telecom's TFP is difficult
but important. Perhaps Telecom could follow the lead of its overseas
counterparts and enlist (more) outside help for its TFP estimates.
Alternatively, if it is confident of its own resources, it should
publish its methodology and data to allow outside commentators to
evaluate and contribute to an important task.
Reducing Real Unit Costs Due to Increasing Sales
In a network-based industry with substantial fixed costs, a major
determinant of reducing unit cost is an increasing level of output.
One estimate for telecommunications in the U.K. suggests that each 1
per cent increase in demand for calls reduces unit costs by 0.3 - 0.5 per cent (OFTEL, 1988, p 9). Hence, apart from the commonly
published growth of sales figures demonstrating business strength,
they also suggest prospects for real unit cost decreases. No doubt
the strong rate of growth in demand for domestic (4% for telephone
and 13% for data services in 1986-87) and international (20% in
1986-87) telecommunications means that this factor has been an
important reason for Telecom's and OTC's declining real unit costs.
But no estimates of its significance is available. Telecom and OTC
should be required to publish estimates of decreasing unit costs due
to this factor (e.g. so that its contribution to the "Xu factor in
the price-cap formula can be monitored).
(c) Dynamic efficiency
For the technologically dynamic telecommunications industry, probably
of greater importance than allocative and technical efficiency, is
"dynamic1' efficiency.
Dynamic efficiency refers to the nature and level of innovation and
entrepreneurship including a company's responsiveness-and adaptation
to changes in technology and consumer tastes and preferences.
The concern here is whether Telecom and OTC are at least keeping
abreast with worldwide innovation in the range and quality of
telecornmunications services offered. As communications becomes
increasingly perceived to be a competitive edge in business, this has
become an increasingly important issue for Australia. Telecom and
OTC list a range of new service improvements and products which they
now offer or which are in the pipeline, but it is difficult to gauge
Telecom's and OTC's dynamic efficiency in this regard without
comparison with the service offerings available in other comparable
countries. Thus, to facilitate such assessment, Telecom and OTC
should be required to compare progress in their service offerings
(including their quality, geographical coverage and ability to meet
demands) against those available in other countries in comparable
periods. One must guard against the possibility though of technology
rather than market-driven service developments.
For instance, in the USA, and probably other parts of the world,
there is a growing suspicion that technology developments, e.g. ISDN,
may be running well ahead of cost-effective industry needs. Moreover
there is concern that if demand falls.short of expectations, the
burden of recovering the high costs of such developments may be
spread over users of basic telephone services - especially those with inelastic demand schedules - as well. Notwithstanding such sensible
concerns about the need to ensure that technology developments are
market oriented and serve'useful business or domestic purposes, the
benefits derivable from new technology are broadly recognised.
OTC stresses repeatedly in its 1986/87 Annual Report that keeping up
with innovations in service offerings is crucial for Australia. And
as Cutler (1987) emph.asises, Telecom is well aware of the importance
of dynamic efficiency but - as with OTC - is hampered by financial constraints:
"Better management of costs and prices will serve little purpose
if Telecom is not offering the range of technologies and services
its users require. This is partly a question of managing
technological change - and notably, in the area of network capabilities, Telecom has generally been more innovative than its
relatively small size in world terms might lead one to expect.
But maintaining an adequate rate of technological advance also
critically depends on investment levels - and it is here the sensitive questions need to be faced. Is it rational to
persistently maintain Telecom's investment levels well below
those warranted by its capital costs and prospective rate of
return - as successive governments, acting in the name of budgetary austerity, have done? Is it truly impossible to place
the relations between Telecom and its owner on a sounder basis,
closer to that found in the private sector, rather than retaining
Telecom's vulnerability to the government's short-term financial
needs?
"These issues are not new - they were raised by the McKinsey
report on Telecom commissioned by the Coalition Government in
1980 and by the Ergas Report in 1986. Yet appropriate action has
not been forthcoming; and without progress in this respect it is
difficult to see how Telecom's long-term efficiency can be
assured." (p 64)
How valid is Telecom's complaint about investment constraints?
According to the figures in Table 16, on the basis of per capita
investment (on a three-year average) during 1979-1983, Telecom's
investment levels compared favourably with most other countries.
Indeed, during the 1981-83 period, Telecom's per capita investment of
U.S.S 311 was almost four times that of Canada's. However, during
1983-85 there was apparently a dramatic decline to U.S.S 75 per
capita, still slightly higher than Canada's rate of U.S.S 73. But as
Table 17 shows, in aggregate terms Australia's investment of
S 1169 million during 1983-85 was considerably less than Canada's
level of S 1839 million.
Table 18 provides figures which indicate the share of investment in
tele.c~mmunication~ as a percentage of Gross Fixed Capital Formation.
Australian investment in telecommunications has evidently declined
since the 3.4% achieved in 1974. In 1985, investment in
telecommunications comprised 2.7% of Gross Fixed Capital Formation
which was slightly less than most other countries in the table,
including Canada (2.8%). Of course, these figures do not take into
account differences in the countries' investment requirements due to
cllmate, topography, demography and economy. And in any case, they
relate to the past. The current and future investment requirements
to enable this country to keep abreast with accelerated developments
in telecommunications equipment and services, raises the issue of
constraints on Telecom's and OTC's freedom to borrow to a new level
of importancelo. This is especially true in the new system of
monitoring and accountability which emphasizes post-decision
monitoring through performance indicators. If a Government Business
Enterprise is to be held responsible for its performance, it seems
only reasonable that as far as practicable, it should not 'be unduly
frustrated in its investment decisions, including their financing.
Amongst the various alternative ways of providing Telecom and OTC
with more investment funds is for the Government to reduce or forego
its dividend requirements from them, thereby serving to build up its equity holding in these vital high-growth, capital-intensive
businesses. Another alternative - if the view persists that borrowings by Telecom and OTC should be tightly restricted - is to allow a portion of Telecom and OTC to be privatised and receipts returned for investment purposes. An added advantage of this measure
would occur if the new part-owners could inject new (complementary)
skills into the telco s'operations. At any rate, the measure will
have the advantage of generating from amongst the new owners,
including the professional analysts who advise them, a new set of
self-interested, motivated, monitors. This advantage was evidently a major consideration in the New Zealand decision to sell a portion of
its telecommunications corporation and several Government-owned
enterprises to private interests

3. Equity Considerations
No doubt, equity (or "fairnessw) considerations are as, if not more,
important to policy makers (and the electorate) than seemingly
esoteric efficiency concerns, (see eg. Williamson, 1984). The
primary issue concerning equity in regard to telecommunications is
probably contained in the question: what social objectives should be
sought from the telecommunications network and how can they best be
attained? But equity considerations can complicate
telecommunications policy reforms guided by economic rationality.
Indeed, at times, perceptions of equity may conflict with efficiency
considerations,
Universal Service
In common with many overseas telecommunications suppliers, Telecom is
charged with providing universal service, ie "... to provide every household with the opportunity to obtain a telephone at an affordable price ,." (Telecom, Annual Report, 1986/87, p 5). In this task,
Telecom has been demonstrably successful, with a telephone in over
nine out of ten homes and telephone penetration expected to reach 96%
by 1990. As telephone saturation sets in, the focus will be on how to facilitate access to the network for those Australians who would
otherwise be unable to afford one.
These issues of universal service are the subject of concern in many
countries. Writing with a focus on the Canadian situation, Waverman (1988) concludes:
I t . . . the distribution of income can not be altered much by subsidising access .to telephone services. Stated differently, the poor are not poor because of the price of access nor will the aggregate level of access demanded increase much becacse of a general subsidy to access - people at the threshold will take service but the demand of all other residential consumers will be unchanged. If one wanted to subsidise access or price below the - - Ramsey price level in order to produce universal service, it is
more efficient and equitable to subsidise those households at and
below the threshold level than to subsidise all access." (p 14)
(emphasis in original)
I agree with Waverman's conclusion that rather than blanket subsidies
through, for example, holding down telephone fixed charges, subsidies
could and should be more directly targeted to those who need it (in terms of criteria specified by the government). Indeed many
economists have long argued that equity concerns are more
cost-effectively addressed through direct subsidies rather than by
interfering with efficiency-based pricing. Emerging policy decisions
overseas seem consistent with this advocacy. Thus, in the U.S.A.,
there is now an increasingly widespread use of "lifelinev* services,
and direct subsidies paid to those who qualify for assistance on the
basis of federal or state government criteria. In Australia,
however, the Government has decided to continue with the blunt
targetting of cross-subsidy practices, (Minister for Transport and
Communications, 1988).
And as the new telecommunications services become commonplace,
attention will shift onto the meaning and coverage of the aim of
universal service. Should government be concerned to monitor
penetration of new services? Are there implications for public
policy if only business users or the rich are benefitting? Should
the prospect of a society of information "haves*' and vvhave-notsv*
concern policy makers? If so, performance indicators will be
required to facilitate monitoring and policy deliberations.
Cross-subsidies
An issue related to universal service is that of cross-subsidies.
Indeed, in Australia the discussion of universal service has often centred on the provision of telephone facilities to people in rural and remote areas at prices which do not fully cover costs. Attempts to reduce cross-subsidies between metro and non-metro customers
(which according to the Minister of Communications is now worth over $450 mi1lion.a year) and between long distance and local calls, by
rebalancing telecommunications prices to more closely reflect costs *
may well result in currently subsidised customers incurring
significantly higher telecommunications bills.
Moreover, rebalancing based on the principle of Ramsey pricing could
dramatically alter prices. As an example, Bell Canada estimates the
own price elasticity of demand for local service to be -0.04 and the
toll own price elasticity of demand to be -0.8. Therefore, Ramsey or
efficiency criteria would suggest that the percentage mark-ups over
marginal cost on local versus toll, be in the order of 20 to 1, with
local service being taxed much more heavily than toll. (Waverman,
1988). In such circumstances, can it be stated unambiguously that
such moves will lead to welfare improvement?
Unfortunately, economic theory does not provide unambiguous guidance
about whether rebalancing telecommunications prices to more closely
reflect costs (and demand) would necessarily result in welfare
improvement. Since there is likely to be increasing debate over
price rebalancing, this point warrants further discussion and this
occurs in Appendix 1.
The point being made here is that because of the potentially
significant redistributive effects of price rebalancing, equity
impacts should be monitored and considered alongside efficiency
considerations. Thus, Telecom should be required to monitor, and
publish indicators of, the impact of price rebalanclng on various
groups of customers, particularly the poor. This will help ensure
that those considered to be deserving by government will be
assisted. If Telecom is to be the vehicle of such assistance, it
should publish indicators through which its performance in this
regard, too, may be monitored.
Effectiveness
For an increasing number of companies, telecommunications is now
regarded as a strategic resource rather than a business overhead.
The increasingly important role that telecommunications plays in
modern business is the result of technological advances and
socio-economic trends. The convergence of computing and
communications technologies has dramatically increased the potential
of information transmission and processing services available to
business. At the same time, the long-term structural shift into the
service economy is increasingly dominated by the information sector.
These major trends put Telecom and OTC at the leading edge of
Australia's competitiveness and economic development.
Such developments also make it very important that Australia's
telecommunications operations are not only efficient but effective in
the sense of achieving telecommunications policy objectives. And
evidence of this effectiveness should be open to review by outside
assessors. Thus, Telecom and OTC should be required to publish
indicators of how effective their operations have been in terms of
achieving objectives (set in consultation with the Government) .
Certainly, in broad descriptive terms this would not be difficult, as
much of OTC's and Telecom's Annual Reports and the latter's "Service
and Business Outlook" document are already dominated by the aim of
demonstrating their effectiveness. But there is a need to do so in a
way which facilitates assessment. Better, not necessarily more,
information is needed.
One way of providing better information is by publishing, where
possible, quantitative targets and achievements. But quantifying
effectiveness to the required extent will not be easy. Indeed there
are at least five major difficulties with assessing effectiveness
which would be only partially overcome by further continued effort.
These are:
(i) the problem of reducing a dimension of achievement to a quantitative scale;
(ii) the fact that the benefits and costs of many policies accrue over a significant period of time;
(iii 1 the problem of separating out the impact of environmental
factors (as opposed to that of programme inputs and outputs), on the
final outcomes and the cost of their attainment;
(iv) the difficulty of capturing all of the quality information
relevant to assessing outcomes; and
(v) the problem of selecting a small number of summary
statistics to characterise a whole distribution of performance variables, particularly in the absence of an explicit evaluation
function for outcomes.
But some increase in quantitative information will be possible.
For instance, if a reducing international trade deficit (let alone
surplus) in telecommunications equipment is a policy objective,
quantitative information would establish that Australia has certainly
not been very effective. As Table 19 shows, Australia's exports of
telecommunications equipment in 1984 was about $9 million, about the
lowest of comparable countries. By contrast, in 1984 Canada exported telecommunications equipment worth $651 million. As Table 20
indicates, Australia's imports of telecommunications equipment have
been growing strongly, so that in 1984 the trade deficit on this item
stood at $249 million. And expected further developments in
telecommunications are likely to increase this deficit further cnless
measures are put in place to reverse or at least slow down the trend
of increasingly larger deficits.
By contrast, Canada, which had a trade deficit on this item of
$16 million in 1979, five years later, in 1984, had managed to
convert this to a trade surplus of $206 million. So network size is
not necessarily an obstruction. And it is increasingly becoming
imperative that we address those factors that are.
What is required to begin with is for Telecom and OTC and the
Government to agree on a strategy for the development of Australian telecommunications. In doing so care should be taken to avold an
unnecessary imposition of constraints. For instance, a government
-owned telecommunications corporation is not necessarily less
innovative than a privately-owned one as Telecom France has been
demonstrating with its Minitel programme which has involved giving
away terminals to all telephone subscribers (with fees charged for
access to the various services). Nor is a monopoly supplier
necessarily less successful in developing and marketing new products
and services as Bell Canada has demonstrated. Much of the turnaround
in Canada's trade balance in telecommunications equipment, discussed
earlier, has been due to the activities of Bell Canada (and its more
than 80 subsidiaries).
It is true that Bell Canada has a successful manufacturing arm in
Northern Telecom. But if this is what is required, why shouldn't
Telecom develop a similar relationship? One view worth considering
is that part of Telecom be sold to a telecommunications equipment
manufacturing company. Not only would such a sale inlect welcome
capital for Telecom's investment programme, the liaison could have
other mutual benefits as Northern Telecom and Bell Canada have
demonstrated (see Telephony, 1987).
Whilst in the longer term effective competition will be required to
provide substained incentives and/or penalties in favour of market
oriented enterprise, there is much which can be done which need not
await the development of such competitive forces. Moreover as
experience in the USA and UK are indicating, even where permitted,
effective competition could be slow in developing. As the European
Economic Community Green Paper (1987) and various OECD reports (e.g.
OECD, 1988) have shown, many developed countries are recognising the
urgency of reconsidering telecommunications policy. It is
increasingly imperative that Australia adopts the same sense of
urgency in deciding its telecommunications strategy and the roles
that Telecom and OTC should play. And once decided they should be
supported in the pursuits of their tasks and judged by their
performance. As effective competition develops, the market will
provide its acid test of this performance. Until then there must be
more dependence on the sort of PIS which have been the subject of this paper.

I11 PRICE-CAP REGULATION AND PERFORMANCE INDICATORS
The price-cap formula has been used for several years in the U.K. to
regulate British Telecom. And in May 1988, the U.S. Federal
Communications Commission decided to advocate its use, beginning with
AT & T. However, while the price-cap system of regulation does have
merit in the sense that its underlying rationale seems to be to
provide more incentives for economic efficiency, it has its . .
limitations and problems, and these should be recognised if we are to
design an effective monitoring and regulatory system for Australia's
telecommunications industry. The second primary task of this section
is to demonstrate that the sort of PIS suggested in Section I1 will
continue to be required under price-cap regulation.
To begin with, price-cap regulation is hardly new or revolutionary.
There has for long been in practice in Australia a sort of informal
price-cap monitoring for telecommunications and other public
enterprises. As discussed earlier in Section 11, Telecom and OTC
have regularly shown in their Annual Reports how their price
increases have been lower than CPI increases. And other public
enterprises have usually provided similar information in their Annual
Reports. Indeed, in the State of Victoria, this price-cap monitoring
was formalised in 1983 by the Labor State Government through an
explicit requirement that the state's public enterprises (which
include electricity, gas, water supply etc.) do not increase their
prices on average by more than the CPI increase.
What is somewhat new in the telecommunications price-cap system is
the explicit and formal incorporation of a specified 'X' or unit cost reduction factor. This feature has merit and will ensure that
consumers receive some of the benefit of productivity and cost improvements. However, in spotlighting attention on
telecommunications average price changes and on expected productivity
requirements, price-cap regulation does not - indeed, nay reduce - focus on the dynamic efficiency and effectiveness aspects of
telecommunications performance which are at least as important.
This is a potential imbalance in regulatory attention which this
paper warns of and tries to redress. Regulation should be concerned
with improving performance and, as this paper emphasizes, the
indicators of perfomance go well beyond price level and productivity
changes - particularly for telecommunications.
As foreshadowed earlier, we turn now to examine why the PIS discussed
earlier in Section I1 will continue to be required under price-cap
regulation.
1. FinancialIRate-of-Return Indicators Will Still Be Required - -
When a "price cap" is set, regulators must inevitably have to
consider an intended or appropriate rate-of-return, since "too high"
a rate would not be politically acceptable and "too low" a rate would
not be "fair" to the telecommunications operator. And once a
price-cap has been set, regulators will want to continue monitoring
the rate-of-return, since this would be pertinent to revisions in the
formula. As Helm (19871, observing the UK situation, points out:
"X can in fact be chosen on the basis of a whole range of
criteria. Though nominally a price rule, it is these criteria
which determine the sort of animal RPI-X actually is. If rate of
return is the residual criterion (to maximise share proceeds for
example), then RPI-X is not a price formula at all, but rather a
rate of return. It will then suffer from the objections of
cost-inflation incentives outlined above. Though it is difficult
to ascertain precisely what considerations were taken into
account, there can be little doubt that rate of return
considerations have been- used in both gas and telecoms, and it is
therefore not surprising that OFTEL has subsequently investigated
BT's relatively high rate of return (OFTEL, 1986). On a purely
price-based rule, such a study would be irrelevant." ( p 16)
It is important to recognise that since the level of profits attained
is likely to be restricted, incentives to efficiency are also likely
to be restricted. It is true that before the firm has begun to earn
its'acceptable level of profits, there will be incentives for
increased efficiency provided by the prospect of earning increased
profits. However, once, the firm achieves this acceptable level, the
incentives dissipate and the familiar disincentives to efficiency and
cost-padding problems of rate-of-return regulation might be expected
to recur.
Thus, the problems of how the rate-of-return level is to be measured
and how the appropriate target level is to be determined, remain.
Accordingly., asset revaluation, depreciation practices and other
current cost accounting issues will still have to be resolved and
many of the problems which have been discussed in relation to
rate-of-return regulation could remain with a "price capw.
It should be noted, too, that the shorter the period for which a
"price capw is set, the more it resembles rate-of-return regulation
and the less are the incentives to improved efficiency. If the firm
fears that when its "price cap" is reviewed, profits will be driven
down to a minimum acceptable level, it may have a reduced incentive
to seek maximum efficiency in the period immediately before the
review. To sustain incentives for efficiency, it may be preferable
to use a formula whereby exceptionally high profits are shared --.. --between the company and consumers, and where the formula is rolled
forward from one year to the next, so that "clawback" is partial and
operates over an extended period. OFTEL (1988, p 8) considered that
for British Telecom, a "price cap" formula fixed for a time period of
between three and five years is appropriate. The FCC and the
Australian Government have nominated a period of three years.
2. An Input Price Index for the Regulated Firm - ---- - OFTEL has been using, and the FCC and Australian Government are
proposing to use, a Retail Price Index in the "price cap" formula.
However, there may be objections to the use of a CPI since it
represents a basket of retail prices to the consumer, that includes
items which are not part of the input costs of the regulated firm.
Therefore,. it does not reflect the changes in the firm's costs which
would justify increases in the prices of its products. Indeed it is
possible that for telecommunications, the firm's input prices in fact
fall.
The alternatives to the CPI are an industry-based index (if it is to
capture relevant costs) or a cost-of-inputs index.
OFTEL (1988) acknowledged this problem:
"However, there is no readily available index of BT's input
prices (though OFTEL has been examining ways in which an
aggregate index could be put together based upon components
derived from a number of existing sources). Furthermore, the
index should not reflect all BT's actual costs because BT can
influence prices for some of its inputs, and care must be taken
not to remove the incentive to exert downward pressure on these
prices as would happen if they could be passed on to BT's
customers. It may, therefore, be preferable to obtain an
understanding of the general relationship between changes in BT's
(acceptable) input costs and the RPI, and to use this as a basis
for a broad adjustment to the X factor. In the case of the price
control formula applied to British Gas, a particular element in
the formula is the price of gas itself. There does not appear to
be any one input to BT's production process whose price is
outside BT's control and which is so dominant as to require
special treatment. Nevertheless, if it could be demonstrated
that in future years the aggregate index of BT's input prices
would show a movement which was sharply at variance from the expectation for prices as a whole, then this should probably be
taken into account in setting the formula." (p 10)
But the complexity of the problem is illustrated by the FCC's (1988)
conclusion after considering discordant submissions on the issue:
"The CPI, PPI, some subset of either the CPI or PPI, or the
'implicit' GNP deflator, each fails in some way to capture the
costs faced by carriers in the provision of service. We are
therefore proposing the use of an index not named by the
commenters, but which we believe will provide the best available
measure of inflationary changes faced by dominant carriers - the GNP price index (GNP-PI), also known as the 'fixed-weight GNP deflator'. *' (p 196)
An input price index will continue to be of interest. However, as
discussed earlier in Section 11, input prices for telecommunications
could well decrease sharply, eg because of technological change and
economies of scale in the computer industry. Thus, attention to
developing and publishing an input price index continues to be
warranted under price-cap regulation.
Economic Efficiency Performance Indicators
(a) Performance Indicators of Allocative Efficiency
(i 1 The Level of Telecommunications Price Increases
Before setting the price-cap, and before each modification to it, there will be interest in whether the level of prlces at the
commencement of the price-cap period is appropriate. Thus indicators of performance in regard to the level of prices, including
international comparisons, will still be of interest. In addition,
during the period of the formula there wlll be interest in just how
much of the permitted prlce increase is actually used. Moreover, -- tliere ~ I l l also be interest in whether telecommunications prices rlse
faster than in periods before the price-cap system was implemented. (As mentioned in Section 11, Telecom's price increases over the last nine years rose, on average, 5 % per annum less than the CPI.)
(ii) The Structure of Prices
The price-cap formula is concerned with the average level of prices
(of a basket of telecommunications services) and therefore permits
price rebalancing within this average. While this allows more price
flexibility that prices may be adjusted to more closely reflect
costs, there may be concerns that this cost-alignment would not
occur, particularly where competitive pressures are inadequate (see
e.g. Trebing, 1988). Thus there will still be a concern to monitor
whether individual price movements are in line with cost structures.
Moreover, if Ramsey pricing is used to recover the substantial joint
costs of telecommunications supply, this could transgress perceptions
of equity. As we saw earlier, in principle, Ramsey pricing can
result in unacceptably high individual price increases. Indeed, this
concern may precipitate proposals for individual rather than average
price-caps. Such concerns led to an agreement between British
Telecom and OFTEL which constrained individual price increases to no
more than 2% greater than the CPI movement. The FCC proposal limits
changes in individual prices in each year to no more than 5% up or
down (since in the U.S.A. predatory pricing is a concern) unless the
FCC can be persuaded that a larger change is justified at a formal
hearing. In Australia, the Government will "establish separate CPI-X
price-cap arrangements for business and residential subscribers to
ensure that the benefits of efficiency changes are equitably shared
among customer groups" (p 1471, and ". . . The residential formula will limit both the increase in the average price of all standard services
and the change in price of standard access charges" (p 148).
Nevertheless, the Government will be interested in monitoring what
sort of rebalancing is occurring within these broad categories and
whether they are justified by cost structure movements. This means
that PIS concerning changes in the structure of prices will continue
to be required.
(iii 1 Quality of Service
A major concern of price-cap regulation is its potential impact on
quality of service. The worry is that a firm will now be able to
increase its profits not only by increasing revenue, but by reducing
costs by reductions in the quality of service, particularly where
competition is absent or inadequate. Hence, quality of service
performance indicators will continue to be required under the new
price-cap system.
In the U.K., concern has focused on the need to ensure that British Telecom improves the performance of its fault repair service and the
provision of new service. In OFTELfs view:
"This particular aspect of performance is of such importance that
a case could be made for incorporating some kind of financial
penalty in the price control formula were BT to fail to deliver a given quality of service. For example, it would be possible to
reduce permitted price increases by some amount for each failure
to meet a performance target. It would be important in setting
up a foxmula of this kind both to ensure that the particular
measure of quality was of central importance to consumers
(otherwise there would be the danger of diverting BTts resources
wastefully), and that the penalty was set at such a level .that it
affected performance while not penalising the company to an
unreasonable extent. LOF.TEL, 1988, p -11
Some time after privatisation, British Telecom decided to cease its
publication of quality of service reports. Under pressure from
OFTEL, BT recommenced publication of six-monthly quality of service
statistics in October 1987. During the period when BT was not
publishing these statistics, OFTELts chairman considered this
information important enough to conduct and publish quality of
service information generated from customer surveys and this practice
evidently would continue:
"Now that BT has started to publish its own figures it is less
imperative that OFTEL continues a full programme of research into
quality of service. It would not be sensible for OFTEL to
attempt to replicate every year, measures which can easily be
obtained within the BT network. However, I believe that OFTEL has much to gain from conducting independent investigations,
partly because of the important links which such investigations
can forge with consumer and other interests and partly because
investigations of this kind can often identify problems which
need fuller study. My objectives in continuing OFTEL1s work on
quality of service will be to improve my understanding of
consumers1 attitudes to BT1s performance, to obtain evidence
about the reliability of BT's performance, to obtain evidence
about the reliability of BT1s statistics - as necessary, and to cover topics that are not dealt with in BT1s statistics." (OFTEL,
1987, pp 1-21
(b) Performance Indicators of Technical Efficiency
The "X" in the CPI-X formula, is in effect, an attempt to specify a
reasonable expectation about the average reductions in real costs per
unit of output to be achieved by a regulated firm. In other words,
when "X" is 3 the implication is that it is reasonable'to expect a 3
per cent reduction per annum in real unit costs. But determining a
generally acceptable level of "X" will not be simple. For instance,
in the U.S.A., the U.S. Telephone Association proposed a 2%
productivity factor, while the FCC decided on 3%. Individual
carriers are complaining that 3% will require them to double recent
productivity levels.
Although "X" is often referred to as a productivity improvement
factor, as was noted earlier, the unit cost reductions can result
from an increase in the volume of sales, as well as from productivity
improvements. Thus estimates for both will be required.
Volume of Sales. In a network-based industry with substantial
fixed costs - ie in a situation in which total costs do not change in proportion to volume - a major determinant of unit costs is the level of output. As volume rises, unit costs tend to fall. Thus where the
demand for services ii rising rapidly, it makes it easier to achieve
the CPI-X target while making substantial profits. Accordingly, In considering the specific figure for "X" there are two options:
either an assumption can be made about expected increases in volume
over the next three years, and about the effect this would make on
unit costs, or a change could be made to the formula which would mean
that it altered year by year as the volume of demand changed.
An argument against including a separate adjustment for changes in
volume is that increases in volume may be the result not of increases
In demand outside a firm's control, but of the firm's own efforts by
way of advertising or innovation. In such cases it would clearly be
undesirable to establish a formula which discouraged such efforts
they result in a tightening of the formula. OFTEL considers that one
way around this problem would be to avoid adjustments related
directly to volume, but to include an element related to the major
reason for externally stimulated changes in demand - the growth of GDP (OFTEL, 1988, p 10).
Productivity. The major consideration for determining the size of
of "X" is the deduction that should be made for expected productivity
improvements. The simplest measure to derive is that of labour
productivity. But labour productivity is a very partial measure.
Thus, although more difficult to derive, total factor productivity
measures would continue to be of much interest.
(c) Dynamic Efficiency: The Rate of Investment and Innovation
Would a price-cap encourage -dynamic efficiency? Schwartz (1988)
considers this issue in the context of. regulation in the USA and
includes:
"One might also hope for the more rapid introduction of new services and advanced technology than would'3e tle case under
conventional regulation . . . It is true that, in theory, the cap-index approach would discourage uneconomic investment; that
is, investment whose cost cannot be reasonably expected to be
recovered in a relatively short time with prices capped. This is not the same thing as saying that the approach would also be
..-
superior to conventional regulation in encouraging technological
investment that will ultimately reduce costs. On the contrary, one of the consequences of cost-plus regulation is that under certain circumstances, investment may be made even in the absence
of an assured market for the services to be supported by the
investment. The key variable is time. Under conventional
regulation, investment is recovered over a longer period than is
usual under competitive conditions. A cap still might be
superior to conventional regulation in that it encourages
efficiency, but it would be a mistake to conclude that it will be
as effective as vigorous competition." (p 3 4 )
In the USA, the FCC has foreshadowed that it would keenly observe
what in fact does occur in regard to investment and innovation under
price-cap regulation. In the Australian context, too, where less
competition exists, there seems little reason to be confident that
price-cap regulation in itself will necessarily lead to improvements
in dynamic efficiency. As emphasised earlier, deliberate policies
and efforts should address this task and performance indicators will
be required to monitor progress.
4. Equity
We have already touched on equity concerns when discussing price
rebalancing. It was, of course, equity concerns which led to the
formation of rate-of-return regulation,-and equity concerns which
explain why, despite its problems, it survived for so long. And now
it is equity concerns which raise some of the main doubts over
price-cap regulation. Who benefits and who bears the costs? Is this
redistribution fair?
In the U.S.A. Representative Edward Markey, Chairman of the
Telecommunications Subcommittee, called the FCC's price-cap proposal
"the FCC's social welfare plan to redistribute the wealth from
telephone consumers to telephone company shareholders", (Telephony, August 10, 1987, p 10). Certainly Wall Street approved of the
proposal with a rise in the price of AT & T shares.
Where competitive pressures are absent or inadequate, as in Australia, the doubts might be even greater. To what extent will
less cost-padding and/or greater than expected efficiency
improvements be passed on to consumers or simply appropriated by the
firm as higher profits (or government through higher dividends)?
Will strategic behaviour by the regulated firm allow such profits to
continue? (To guard against excessive profits, the New York Public
Service Commission's regulation of the New York Telephone Coinpany
includes a "sharing mechanism" whereby 50 per cent of any return on
equity above 14 per cent is passed back to customers by way of price
reductions.) The efficiencies sought by the firm, eg., through price
rebalancing, could hurt some, whilst benefitting others. Is this a
welfare improvement? What if those adversely affected are the poor?
Will innovations in service offerings be affordable only to business
and the well-to-do? Which groups will need assistance and in what . - - . . -
way(~)? In order to at least partly allay such concerns, the impacts
on various sbcio-economic-geographic groups could be reported on by
Telecom. And if Telecom is required by the Government to deliver
assistance to those deemed to be deserving, then indicators which
facilitate assessment of Telecomls performance in this regard will
also be required.
5 . Performance Indicators of Effectiveness
Finally, and most importantly, performance indicators of
effectiveness - the extent to which longer-term strategy and pollcy objectives are being achieved - will still be required under price-cap regulation. As discussed earlier, it will probably not be
easy to identify and apply such performance indicators for
effectiveness, but it will be necessary to do so. Sustained effort
should lead to improved PIS and, in the process, also result In a
clearer understanding of strategic and performance objectives for
telecommunications in Australia. - - - -- - -- - - - --
CONCLUSIONS AND RECOMMENDATIONS
The conclusion of this paper need only be very brief. This will
allow space in an already long paper to be devoted to making
concluding recommendations regarding the conditions required for
effective use of a system of PIS.
The primary conclusion regarding PIS is that, used judiciously, they
can be useful in monitoring aspects of performance and in identifying
areas of poor performance requiring investigation and remedial
attention. This paper has advocated that the rage of PIS used for
telecommunications include indicators of financial, economy,
efficiency, equity and effectiveness performance. However, merely by
the Government issuing a guideline that the telecommunications
suppliers and other Government Business Enterprises (GBEs) develop,
use, and publish PIS, will not ensure their effective use in ways
which do, indeed, allow improved results-oriented assessment, and
serve to encourage and facilitate improvements in performance. Such
effective use depends on the existence of several enabling factors
pertaining to the use of PIS. In other words, how well PIS perform
will depend on the extent to which these factors exist and prevail.
Some of these factors are discussed below.
1. There must be clearly specified objectives for GBEs and firm
government commitment to a system of post-decision appraisal. This
includes an acknowledgement that such a system minimises the
requirement for =-decision approvals. To require that GBEs be
judged by results, particularly those suggested by the published PIS
which are agreed upon, and yet continue to require the performance-
inhibiting approvals of the past, will soon lead to GBE frustration
and probably dysfunctional behaviour.
- 71 - . .
2. GBEs will also need to be firmly committed-to the system of
post-decision appraisal through the use of PIS. And they wlll need
to be committed to the aspects of performance that the PIS are to
measure. To engender such commitment, it is important that the
aspects of performance which the PIS are designed to measure, are
considered to be key aspects. Otherwise, not only will the nominated
PIS attract management attention and resources from other more worthy
areas, but the PIS will fail to sustain the support of management and
this will soon impact on the success of the new results-oriented
regulatory system;
3. The aspects of performance suggested in this paper should at
least provide a basis for discussion about the crucial aspects of
performance. Most GBEs would probably agree that economy,
efficiency, equity and effectiveness are amongst the broad components
of performance that should be pursued. But it is, of course,
essential that the Boards and management of GBEs be closely consulted
about the development of PIS. And, after some experience with PIS,
they should be consulted.again regarding ways of improving the system
of PIS. This co-operative development mlght (hopefully) reduce the
potentially adverserial nature of a PI system. But the development
of a system of PIS should not be left entlrely to a GBE since there
is the possibility that the short term benefits of "strategic"
selection of PIS might seem more obvious than the longer term
benefits of an effective system.
4. Once the specific indicators are decided upon, their development
and effective use will depend upon the availability of adequate and
reliable data. And there must also be confidence that the PIS are
indeed measuring performance. This is because there is widespread recognition of the potential for strategic misrepresentation that
information asymmetry offers many GBEs. To foster trust in their commitment to the system and an appreciation of data sources and
difficulties, GBEs should allow external assessors to inspect, "on
siten, the way that their data is compiled from scratch.
5. External assessors, including Parliament, consumer groups and
academic commentators, should find the PIS understandable and useful
to the task of performance monitoring and assessment. Otherwise,
interest in PIS will wane and, subsequently, so too will the pressure
for further development and improvements to the PI system. If this
occurs, the pressure could well build up to swing the "control
pendulum" back the other way, i.e. towards increased controls.
6. The internal users of PI information - GBE management - must find the PIS relevant to their task of assessing performance for the
purpose of facilitating management decisions and performance
improvement. After all, the ultimate objective of the system of PIS
should be not just to monitor but to encourage and assist an
improvement in performance. If the PIS required to be published are
not relevant and useful to a GBEs board or management, there is the
possibility that two sets of PIS will develop. One set for external
display and another unpublished set used internally by management
(which is in fact more relevant to decision making and performance
improvement). More research is required into GBE management views of
performance indicators. One notable problem in designing management
- relevant PIS, which is sometimes raised, is that the level of aggregation required for external and internal use of PIS may
conflict. Whereas many external assessors - and probably top management of the GBEs - will focus on aggregate indicators of price increases, revenue, costs, TFP etc, such a level of aggregation might
be of little use to down-the-line managers of smaller units within
the GBE. What is required is management indicators which are
sufficiently disaggregated so as to be useful to middle management
but which can be reliably aggregated to the level of the PIS which
are published in Annual Reports. Perhaps such a system could be
devised where the GBE is firmly committed to the PI system being
used, since this would align individual managers to be, in turn,
similarly committed. Moreover, such an alignment of management
effort would be crucial in nurturing the development of the change in
"corporate culture" required for sustained performance-oriented
behaviour.
7. This alignment of management values is more likely where a GBE's
own performance evaluation of its managers and the rewards and/or
penalties it accords them, is based, at least in important part, on
achievements as demonstrated by the published PIS. However, rewards
and penalties should be tied closely to outcomes that are in fact
within managerial control. It makes little sense to reward or
penalise management for outcomes due to environmental factors which
they cannot affect. But it might be very difficult to avoid doing - - . .. ---
this in practice because of the problem of sorting out the impact of
effort from those of environmental factors.
8 . The implementation of price-cap regulation will not reduce the
need for PIS, indeed it seems likely to encourage the use of PIS by
GBEs. According to Wheatley (1987):
"Since privatisation, British Telecom has invested heavily in new
accounting systems aimed at providing much more information about
product costs. It now has specific obligations to avoid certain
cross-subsidies, e.g. between the network and the apparatus
business, which it did not have as a nationalised industry and
the pressure of competition has also revealed many inadequacies
in the costing system that is present. A valid question here
would seem to be why its old owners, the government, did not
insist on these reforms being made before.
"It is true that the real unit cost indicator was tried, but it
proved difficult to use for internal control purposes and lacked
apparent relevance to managers. The trigger to a much greater
interest in costs was provided by the changed regulatory
mechanism whereby cost savings could be retained within the
company. RPI-X is a much greater incentive than rate-of-return.
This change could have been made at any time in the past 25 years
and it is again interesting to wonder why it was not done when
the industry was publicly owned." ( p 18)
Well, in Australia it will be, at least in regard to
telecommunications.
9. The reforms in regulation should not be seen as a substitute for
increasing the use.of various cost-reducing approaches. Most
importantly they should not substitute for enabling and encouraging
an increase in the level of effective competition faced by the
telecommunications and other GBEs. After all, an underlying guiding
principle of price-cap regulation is to simulate the incentives of
competitive behaviour. Where effective competition can exist, it
should not be restricted.
But neither is the absence of effective competition a convincing
reason to restrict the telecommunications and other GBEs from
engaging in activities which are performance-improving and which are
consistent with the results of competitive or contestable markets.
This paper has referred in particular to two areas of pressing
concern in telecommunications - improving dynamic efficiency and effectiveness performance. These concerns are unlikely to be
adequately addressed by price-cap regulation whose focus will be more
directly on price and productivity changes. It is increasingly
imperative that the role to be played by Telecom and OTC in a
strategic pursuit of dynamic efficiency and effectiveness not be
restricted.
10. As evidenced by statements made by Telecom, at least some GBEs
now accept that competition can bring about pressures for beneficial
change. Indeed, for Telecom the very prospect of increasing
competition is already having a significant influence, including
being more "customer driven". This is an encouraging sign that a
gradual, judicious increase in competition will sustain similar
incentives for continued adjustment and improvement in performance.
And, used effectively, PIS can assist in guiding the nature, extent
and speed of the adjustment.
APPENDIX 1 : WELFARE CRITERIA AND PRICE REBALANCING
Consider briefly five criteria of welfare improvement:
1. The "Pareto" criterion whereby a policy improves welfare if there is some gain and no-one is made worse off.
2. The Kaldor-Hicks "potential Pareto improvement" criterion whereby a measure is considered to improve welfare if the gainers could compensate the losers and still feel better off.
3. A change can be regarded as a "Pareto improvement" if it can be shown that the "losers" from rate rebalancing would be even worse off without these rate changes.
4. A change is a llRawlsian'' improvement if it can be shown that the "most disadvantaged group is made no worse off1*.
5. A change is an "incrementally superfair" improvement if "any individual prefers the changes in the prices he faces to the changes in the prices (consumption bundle) of any other individual". (Baumol, 1987).
Applying these criteria to rebalancing telecommunications prices in Australia, eg. higher access and lower toll prices, leads to the following results:
1. The measure is not (necessarily) "Pareto optimal" since there are losers.
2. The measure could be "Pareto optimal", since the substantial net gains that have been estimated from such price rebalancing. (~lbon; 1987 b) show that.after rate rebalancing, winners could compensate losers and still be better off. Of course, no such compensation may be forthcoming.
3. An improvement under thewPareto improvement" criterion does not seem demonstrable (at least in current circumstances).
4. Price rebalancing is clearly not a "Rawlsian" improvement (unless - government policy undertakes to insulate the most disadvantaged group from being made worse off).
5 . Price rebalancing is unlikely to be "incrementally superfair".
There has also been a number of papers - notably by Feldstein - which have addressed specifically the use of distributional criteria to be used in public enterprise pricing. However, Waverman (1988) concludes that the practical guidance they provide is disappointing.
ENDNOTES
1 Thus the range of PIS in this paper are proposed within the rationale of a 'performance contracting systemf whereby the Government 'contracts' to require consultation in the development of long range strategic plans but only minimum pre-decision making approvals, so long as its enterprises perform satisfactorily in terms of agreed criteria and PIS. This sort of performance contract has been formally used in France and Korea and has been advocated by several commentators as being suitable for broader use. Of course, the rationale of performance contracts could be less formally applied (as is advocated here).
2 The brief discussion on the preconditions for effective use of performance indicators, in Section IV, draws on a longer analysis which, although important for the effective use of PIS, had to be deferred to a subsequent paper in order to keep this one within reasonable length.
see Patrick Xavier MINDING EVERYBODY'S BUSINESS - Performance Indicators for Public ~ n t e r p r i s e p a n c e Indicators for Australia's Postal Services: How Well Will They Perform? (forthcoming)
3 These are frequently referred to as the '4Es' . The coverage of these concepts will satisfy those who would prefer to use a '3Cs" categorization, viz., customers, cost and competition (see Heald, 1987).
The return on equity figure - now evidently widely used in the private sector as a summary measure of financial performance - is not published probably because of unresolved arguments about whether, and, if so, how much of Government loans to Telecom should be treated as equity.
The allowed rate of return on AT&Tts regulated services is 12.2% (reduced from 12.75% in 19871, AT&T earned a 14.4% return on average equity (including regulated and non-regulated business). The Local Exchange Carriers also had their allowed rate-of-return reduced from 12.75% to 12.2% in 1987 due to a fall in the cost of capital. Bell Canada's permitted return on equity was 12.25% to 13.25% in 1987.
6 More specifically, Albon observed that Telecom ' s major departures from efficiency principles of pricing include the following:
. access charges cover far too little of the total cost relative to usage charges given the size of "overheadw costs relative to variable ones;
. long distance charges are far above marginal costs both at peak and off-peak periods;
. while varying according to distance, duration and time of day, STD charges do not vary with density (eg Sydney-Melbourne charge is same as Young-Broken Hill charge);
. local charges, especially metro ones, are far above peak and off-peak marginal costs and do not vary with time of day or duration; and
. particular services (eg directory assistance, public telephones, telegrams and data services) are run at large losses and must be made up from profits from other services, creating deadweight losses at both ends.
This is a major concern relating to the introduction of price-cap regulation in the USA.
It is true, however, that as portable cellular telephones become widely used, there will be less need for payphones to service transit users, although-the need for payphones will persist, e.g. to service areas of relatively low telephone penetration.
9 Bell Canada disclosed that ". . . , we have increased our productivity, the efficiency of our people, by 4.5% to 7% a year for the past three or four years. This is tremendous when you consider that as a whole the industry at large has increased by less than 1% (Telephony, 1987), It was not clear from the article whether Bell Canada was referring to labour productivity or TFP.
lo~his issue receives more attention in the Report of the House of Representatives Standing Committee on Transport and Communications (1987).
