Meeting User needs cost-effectively

Toward increased coherence in the international Trade by Enterprise Characteristics (TEC) framework

Nordic Statistical Association 2013 14th – 16th august 2013

Page 2: Oppgavegiveren: Meeting user needs cost-effectively

Increased user-demands for trade data disseminated at the micro-level

The question is not solely “what do countries trade?” but “what kind of enterprises is behind that trade?” (size, activity, ownership etc.)

Respond: the Trade by Enterprise Characteristics (TEC) database since 2005

Links micro-data from ITGS with the Statistical business register (SBS), however:

Despite high degree of coherence, several methodological challenges remain unsolved

Services are not included but STEC-database in pipeline

Short introduction and outline

The paper include two different issues regarding

Trade by Enterprise Characteristics

This presentation will present these two issues

independently:

1. The issue of complex enterprises and estimated trade

2. The issue of adapting the TEC framework to the ITSS

Short introduction and outline

Page 4: Oppgavegiveren: Meeting user needs cost-effectively

SBR’s handling of complex enterprises is insufficient

for this purpose

“Complex enterprises” identified by use of the

superior number (UHO-system) which is unique to

the Danish ITGS

The UHO system provides an automated method for

identifying complex enterprises by providing a

linkage of legal units that are financially interrelated

(“enterprise group”) through the allocation of a

superior number (UHO-number).

Page 5: Oppgavegiveren: Meeting user needs cost-effectively

508 complex enterprises (out of ~8000 enterprises) with 1986 legal numbers

26 pct. of total exports, 22 pct. of total imports

Most have only two legal numbers (291) but 58 have more than 5 legal numbers

These complex enterprises often report trade on a legal number with no or very few employees; and often legal units within the same complex enterprise have many employees but no trade

→ A lot of trade is matched with a “wrong” legal number in the SBR

Treatment of complex enterprises

Page 6: Oppgavegiveren: Meeting user needs cost-effectively

Suggested solution

The high-number of complex enterprises combined

with a relatively low number of “very complex

enterprises” suggests that a two-string approach

combining an automated process with a manual

“check-and-adjust” follow-up on the most

complicated enterprises is appropriate

Step 1: Establish the link between traders and enterprises on a monthly basis.

Step 2: Use the one-to-one and many-to-one linkages to calculate the median trade M (import and export taken together) per person employed per activity group.

Step 3: For all traders in one-to-one or many-to-one linkages between traders and enterprises allocate monthly trade to the one and only identified enterprise.

Step 4: For all enterprise in one-to-many linkages between traders and enterprises calculate an estimated trade E by multiplying M with the number of persons employed by the enterprise.

Step 5: For all traders in one-to-many linkages between traders and enterprises allocate trade proportionally to E over all identified enterprises.

~10 pct. of the total sum of estimated trade is

allocated to specific UHO-numbers, i.e. estimated

trade is currently impossible to allocate to the

enterprise level

The estimation-process as such is based on

individual UHO-numbers…

…but the subsequent allocation of estimated trade to

specific countries and goods is not, which impedes

the allocation of such trade to individual enterprises

Allocation of estimated trade to appropiate legal numbers

Page 9: Oppgavegiveren: Meeting user needs cost-effectively

Allocation of estimated trade to the enterprise-level

should be secured through an improvement of the

current system for allocation of estimated trade to

specific countries and goods.

When all estimated trade is allocated to specific

UHO-numbers, it can then be allocated further to

legal units by the automated process.

Conclusions

The issues of complex enterprises and allocation of

estimated trade when compiling TEC data need to be

addressed to secure a more robust TEC statistics

Not least seen in the light of new data requirements (export

intensity and more detailed classification by activity sector)

Different sources in the ITGS and the ITSS

…leads to new challenges

Distributing estimated trade to enterprises not included in

the sample

Representivity of population

ITSS

Total population

~40.000 enterprises

Survey

~1.500

enterprises

Page 13: Oppgavegiveren: Meeting user needs cost-effectively

Trade reported by ~1500 enterprises in the ITS

survey can be linked with SBR

Covers roughly 80 pct. of total service trade

Represent around 40000 enterprises

Other sources cannot be linked with SBR

Some cannot be linked due to the current method

- E.g. ITGS, government services and some insurance services

Other due to nature of the transaction

- Mainly the travel account

Page 14: Oppgavegiveren: Meeting user needs cost-effectively

A closer look at the ITS survey

Directly reported trade covers ~85 pct. of the total trade in

the ITS survey (~68 pct. of the total ITSS)

~15 pct. has to be distributed to the rest of the population,

i.e. the ~38500 enterprises (40000 – 1500)

No correlated administrative data source available to help

distribute the estimated trade

Using a non-correlated variable, such as employees, has

certain drawbacks

- No “zero reporters” since all enterprises have employees

- Variance from the non-correlated variable is inherited by the ITS

Page 15: Oppgavegiveren: Meeting user needs cost-effectively

What you cannot do when distributing with a non-

correlated variable

Count the number of enterprises engaged in ITS

Classify ITS by the non-correlated variable (e.g. by size if

number of employees are the non-correlated variable used

for the distribution of trade)

Classify ITS by other variables that are highly correlated

with the variable used for the distribution of trade

What you can do

Classify trade on a more aggregated level that are not highly

correlated with the variable used for the distribution of trade

ITS survey updated roughly every 5 years

Population is ”frozen” at a given year (current population is

from 2007)

Mergers, exit, and entry change the composition of the

population over time

Matching ITSS population with SBR

Enterprises not found in SBR 2010 3.710 Total number Enterprises in 2007 snapshot 40.653

Enterprises in SBR 2010 not represented by ITSS population 4.501

Enterprises matching SBR 2010 and ITSS population 35.063 Share of total enterprises in 2007 snapshot 86,2 %

Page 18: Oppgavegiveren: Meeting user needs cost-effectively

Conclusions

~68 pct. of the Danish ITSS can be directly linked with SBR

and produce unbiased TEC statistics

~12 pct. can be indirectly linked using a non-correlated

variable and can be used to produce some TEC statistics on

a more aggregated level depending on the variable used

~20 pct. cannot be linked with the SBR due to

methodological issues or by the nature of the trade

ITS survey loses representivity over time but the effect is

quite small (1.3 pct. of total trade in 2010)
