Introduction to Parts I & II
Keynesian theory:
In the source of Keynesian theory, "The General Theory of Employment, Interest, and
Money," John Maynard Keynes purports to provide a "general theory" for self-regulatingcapitalist market systems. He asserts that it is applicable generally in all economic
circumstances. Classical concepts, on the other hand, operate only in those rare "special"
circumstances where full employment is possible.
With disconcerting frequency, Marxian stupidities were invoked with approval, althoughin only one instance explicitly crediting Marx.

However, it is Keynesian theory that - if applicable at all - is applicable only in very
narrow circumstances - like the "special" circumstances of the depths of the Great
Depression where political leaders proved incapable of reforming the fundamental policystupidities that prevented recovery.
Keynes nevertheless successfully convinced multitudes of supposedly knowledgeableeconomists to accept a series of black-is-white arguments. Savings became bad and
deficits became good, and the prudent accumulation of reserves for foreseeable and
unforeseeable contingencies was imprudently responsible for disastrous consequences.The accumulation of capital assets becomes an economic obstacle rather than an
economic advantage. Investment and employment is stimulated by inflation and hindered
by price declines. Market liquidity becomes more of a problem than an advantage.
Free trade has disadvantages and closed economic systems have advantages because of
the greater ease of manipulating the latter. With disconcerting frequency, Marxian
stupidities were invoked with approval, although in only one instance explicitly crediting
Marx.Although controversy over war debts and other international debts and trade war
protectionism was raging around him, Keynes has not a word to offer about the obviousroles of such government policies in the business cycle in general and the Great
Depression in particular. See Great Depression Chronology Series, beginning with "
HYPERLINK "http://www.futurecasts.com/Depression_descent-'29.html" \t "_top" µTheGreat Depression: The Crash of '29§."
Keynes provides a rationale for pursuing short term relief from economic problems bymeans of budgetary deficits and monetary inflation - palliatives that must ultimately just
make matters considerably worse.
Over a century of capitalist economic history was thus ignored, as were all arguments
to the contrary, until Keynesian theories were put to the test in the 1970s - and predictably failed miserably wherever pursued.
Nevertheless, Keynesian concepts are once again popular and in use today - especiallyin the United States under the Bush (II) administration. They remain very popular with
political leaders, since they provide intellectual cover for doing what political leaders
have always done when seeking to put off confronting the real problems that afflict aneconomy. Keynes provides a rationale for pursuing short term relief from those problems by means of budgetary deficits and monetary inflation - palliatives that must ultimately
just make matters considerably worse.

The influence of Marx:
It is evident that Keynes rejected much of the worst of Marxian doctrine. Keynes relies
on competitive markets to allocate resources where Marx naïvely relies on socialistdirectives. Keynes uses market exchange values instead of Marx's impractical concept of industrial labor use-values. Keynes had infinite faith in paper money managed by
governments - Marx had none. (Both are wrong on this last one.)
Keynes can thus omit all of the twisted indeterminate and nonfunctional definitions
and redefinitions of economic terms that Marx relied upon for the defense of his narrowindustrial labor use-value concept and for support of his propaganda myth. Profits -
frequently referred to as "income" or "yields" - takes its obvious place for Keynes as adetermining factor for capitalist economic activity. Although he views capitalism asunable to operate at optimal levels for any length of time, Keynes recognizes - unlike
Marx - that capitalism is inherently stable within the parameters of the business cycle.
Moreover, Keynes avoids many of the weaknesses of logic that permeate Marx's work.See the series of articles beginning with HYPERLINK
"http://www.futurecasts.com/Marx,%20Capital%20(Das%20Kapital)%20%20Vol%201%
20(I).htm" \t "_top" µKarl Marx, "Capital (Das Kapital)" vol. 1 (I)§, "Value Determined by an Abstract Labor Standard."
Keynes, like Marx, ignores the particular reasons why particular periods of economic
trouble have taken place.
Keynes appears totally ignorant of the inherent inefficiency of government management.
Nevertheless, Marx's "mature capitalism" fallacy - for which Keynes cites Marx
with approval - is the central feature of the General Theory, and Keynes relies upon someindeterminate concepts of his own to support his "mature capitalism" theme. In the
process, Keynes, like Marx, ignores the particular reasons why particular periods of
economic trouble have taken place.
Like Marx, Keynes believes the ownership interest is not an essential element in
capitalist productivity. Stock market investors are "functionless." Ignoring Adam Smith'swarnings about the weaknesses inherent in the separation of management from
8/14/2019 Keynes theories
http://slidepdf.com/reader/full/keynes-theories 4/34
ownership, Keynes agrees with Marx that good management and supervision is always
readily available and can be procured simply by offer of a suitable salary.
Like Marx and all socialists, Keynes appears totally ignorant of the inherent inefficiency
of government management. See, " HYPERLINK
"http://www.futurecasts.com/Government_futurecast.html" \t "_top" µGovernmentFuturecast§," Part II, "Government Management." He has total faith in the capabilities of
government and "community" administered economic systems. While Marx offers broad
socialist solutions, Keynes offers narrower administered solutions directed at controllinginterest rates, directing investment flows, redistributing wealth, and ultimately directing
the activities of major business entities.
To entice the credulous, Keynes like Marx offers a vision of an impossible utopia. If a
capitalist system is resolutely stimulated pursuant to Keynesian policies, it will generateabundant capital assets - "full capitalization" - so that capital assets are no longer scarce.
Then, there would no longer be any need for financiers and rentiers. While residual
entrepreneurs would continue to be tolerated, Keynes agrees with Marx that theentrepreneur will become unnecessary. See, HYPERLINK
"http://www.futurecasts.com/Keynes,%20The%20General%20Theory%20(II).htm" \t
"_top" µKeynes, "The General Theory of Employment, Interest, & Money§," Part II,"Interest Rates, Aggregate Demand, and the Business Cycle."
Keynes - also like Marx - assumes that the study of economics is a "scientific" endeavor.
He thus avails himself - or at least succumbs to - the "science" propaganda ploy that was
a central feature in the propaganda myth created by Karl Marx. His followers wouldardently continue this propaganda deception until forced to retreat somewhat by their
gross failures in the 1970s.
The savings gap:
Keynes provides us with psychological propensities to consume and save. He blames
the business cycle and involuntary unemployment on the notion that wealthy nations -"mature" capitalist systems - will inevitably save more than can be profitably invested,
leading to periods of economic decline - if not chronic economic decline. Like Marx's
concepts, none of this can be measured, and in fact all the evidence is exactly theopposite.

As assets accumulate, people and businesses can - and observably do - rely more on their asset wealth than on monetary savings.
The decline in savings rates in the U.S. in recent prosperous times has been notorious for decades.
Mature - wealthy - capitalist systems require and have lower rates of savings - not
higher. As assets accumulate, people and businesses can - and observably do - rely more
on their asset wealth than on monetary savings. Their asset wealth supports vast increasesin the purchasing power of credit, naturally stimulating both consumption and
investment, with profit rates and interest rates sensitively adjusting these flows except
when other factors undermine the pertinent markets.
Except during the depths of already developed severe depressions, financial
intermediaries and the money markets have no trouble instantly putting all savingsto work in commerce. As is repeatedly pointed out throughout the articles on Marx,
"Das Kapital," and Keynes, "The General Theory," there is absolutely no evidence that
excess savings play any role in initiating periods of economic distress.
In fact, savings declined substantially in the last full year before the Great Depression -
the first decline since WW-I - accompanied by a substantial decline in the number of
savings accounts. The decline in savings rates in the U.S. in recent prosperous times has been notorious for decades.
Considering the extent and nature of man's weaknesses - and the stubbornness with
which policy stupidities are frequently maintained, it is astounding that capitalism can
function as well as it does.
The roots of the business cycle are to be found in the multitude of pertinent
weaknesses of man - NOT in weaknesses alleged in capitalism. Indeed, considering theextent and nature of man's weaknesses - both in the private sector and government sector
- and the stubbornness with which policy stupidities are frequently maintained, it is
astounding that capitalism can function as well as it does.
It is always the nitty-gritty of analyzing particular factors involved in particular periods
of economic distress that is required for an understanding of the business cycle.Economists who are too lazy or inept for this task - or unwilling to offend political
patrons or private employers - have nothing to tell us. No simplistic "General Theory"
will suffice.

Labor Market Theory
Labor markets:
Theories of supply and demand in labor markets are attacked by Keynes.
Contemporary theories purported to show how labor markets balance factors of supplyand demand to assure reasonable levels of full employment, and to correct periods of
anomalous conditions. However, by 1935, when "The General Theory" was published,
such theories looked like lame ducks.
Full employment is a "special" case in capitalist economics - labor markets clear at
reasonably high levels of employment only during certain special periods of full
employment - and the natural course of capitalist economics - the "general" case - is for
employment levels to fall well short of full employment.
The Great Depression had ravaged diverse nations all around the world and left
hoards of men unemployed and underemployed for half a decade. Clearly, contemporarylabor market theories provided no explanation for what was observably occurring -
something Keynes spends an initial chapter emphasizing.
However, Keynes never addresses the particular reasons why this should be happening.
Instead, he merely assumes that full employment is a "special" case in capitalist
economics - that labor markets clear at reasonably high levels of employment only duringcertain special periods of full employment - and that the natural course of capitalist
economics - the "general" case - is for employment levels to fall well short of full
employment.
This basic assumption of Keynes is thus very similar to that of Karl Marx. The
assumption substitutes for any functional examination of the actual causes of the Great
Depression and lesser periodic economic downturns. Like Marx, Keynes presents the prospect of periods of massive and intractable unemployment as a natural feature of
capitalist economics.
Professor Pigou:
Classical theory recognizes the obvious qualification that competitive labor markets
like other markets can be prevented from clearing by market imperfections.
8/14/2019 Keynes theories
http://slidepdf.com/reader/full/keynes-theories 7/34
Labor markets clear to the point "where the utility of the marginal product balances thedisutility of the marginal employment," according the classical theory as presented by
Pigou.
• There is "frictional unemployment" caused by such things as seasonal or other
intermittent work, the time required to find new work when a job is terminated for any reason, and similar factors.• There is also "voluntary unemployment," which includes those who refuse or
are unable to work for any of a variety of reasons.
• And, of course, market imperfections - such as unions and cartels and
government requirements - will impact results.
"Subject to these qualifications, the volume of employed resources is dulydetermined, according to the classical theory, by the two postulates" that wages equal the
marginal product of labor, and that the utility of the wage when a given volume of labor
is employed is equal to the marginal disutility of that amount of employment. The latter
postulate, however, is not objectively determinable. It is subjectively determined by eachindividual worker.
"But these two categories of 'frictional' unemployment and 'voluntary' unemploymentare comprehensive." Classical theory rejects the possibility of "involuntary
unemployment" in competitive markets.
Keynes, however, touches on another factor, but without further comment. The "output"
from the employment of labor and capital is determined only after a deduction of all
"other costs" besides the costs of wages and capital. (Thus - a far bigger factor today thanin the 1930s - regulatory costs and payroll taxes and other non-wage labor costs can have
a direct impact on labor markets.)
Labor markets clear to the point "where the utility of the marginal product balances thedisutility of the marginal employment."
The particular presentation of the classical theory that Keynes uses as his target is
that of Professor A. C. Pigou, a prominent English economist. Pigou provided a
macroeconomic econometric description of the national labor market.
Due to the need for oversimplification in all macroeconomic econometric presentations,
Pigou's work is necessarily invalid. Substantial outcome determinative factors are
necessarily omitted. Everything that cannot be described as an equation is necessarily
omitted. Problems of measurability and definition inherently permeate all macro-econometrics. Macroeconomic statistics inherently include gross inaccuracies. See, "
8/14/2019 Keynes theories
http://slidepdf.com/reader/full/keynes-theories 8/34
HYPERLINK "http://www.futurecasts.com/Economic_statistics.html" \t "_top"
µEconomic Statistics and Macro Econometrics, The Figures Lie."§
Explaining with admirable insight why such problems are inherent in all macro-econometrics, Keynes jumps on those that afflict Pigou's work. He quickly attacks "the
tacit assumptions, which govern the application of his analysis, [that] slip in near theoutset of his argument."
The labor market has significant peculiarities. Its supply and demand schedule is
inherently complex because of the nature of the supply - human labor. These factors must be kept in mind when evaluating any labor market theory - including that of Keynes.
• When goods cannot clear a market, businesses face costs for storage so the goods
are sold at discount or are scrapped. When businesses can no longer profitably
serve a market, they decline or go out of business. However, unemployed workers
don't disappear. They find ways of surviving. The surplus retained inventory problem is thus always more severe.
• Labor can - and during the Great Depression frequently did - work for food and/or
lodging without a "wage" that could be included in the national statistics.Although not sustainable as a permanent matter in those years before the welfare
state - such laborers didn't support families - this could suffice even for a period
of years. People hung on as farm hands or shop broom pushers or pushcartvendors or as smallholder farmers, yet were properly classified as "unemployed"
since they were still anxious to find wage work.
• Wheat and capital and mass produced goods are fungible. Labor is not fungible.
Skills are not fungible. In particular, agricultural skills are of little use inmanufacturing or most services. Even unskilled labor varies in levels of strength,
dexterity, reliability, educability and education. This became especially important
in 1930 and thereafter with the collapse of the export markets for grains and
cotton and thus the collapse of the entire U.S. agricultural sector - still a hugesegment of the U.S. economy in the 1930s. There was a collapse in auto exports -
about 20% of the U.S. market - at the same time.• Labor mobility operates under significantly greater constraints than the mobility
of products or capital - especially in small nations.
• Trade unions and collective bargaining, in any event, have an impact on
competition not reflected in labor market theory.• And, as stated, it is the factors of supply in the labor market that are subjective
and fuzzy, not the factors of demand.
Thus, labor market adjustments are never precise or rapid - even without modern factors
of rigidity.
8/14/2019 Keynes theories

Pigou ignores influences outside the labor sector that may impact "the rate of interest or the state of confidence."
Pigou assumes there is no "voluntary unemployment," Keynes points out. All whodesire work can find it if they are just willing to accept low enough wages. Pigou
assumes "that the rate of interest always adjusts itself to the schedule of the marginalefficiency of capital in such a way as to preserve full employment."
However, this ignores influences outside the labor sector that may impact "the rate of
interest or the state of confidence," Keynes properly notes. Both of these factors are
major variables, either of which may impact risk-reward ratios and thus investment.
Without such factors, Pigou's work is limited to the "special case when marginal labour-
cost is equal to marginal prime cost" - when all factors extraneous to Pigou's work andaffecting employment permit full employment.
A rise in prices relative to wages will create an increased demand for labor that is
frequently satisfied without any increase in money-wages. This is proof that involuntary
unemployment existed from which such demand could be satisfied.
Pigou's labor market supply and demand schedule thus explains "what level of real
wages will correspond to any given level of employment." It "is not capable of telling uswhat determines the actual level of employment." It has no bearing on "involuntary
unemployment."
In similar manner, Keynes duly pokes holes in existing labor market theories that
purport to explain how market influences tend towards reasonable levels of full
employment. Especially during the midst of the Great Depression, such theories clearlydidn't reflect reality.
Workers resist reductions in money wages far more than reductions in real - inflation-
adjusted - wages unless the latter reach severe proportions. However, labor market theoryassumes that workers respond to fluctuations in real wages. The theoretical relationships
between employment levels and real wage rates simply aren't there in the real world. A
variety of other factors besides wage levels impact price levels and thus real wages.
Money wages in fact fell fairly sharply in the first three years of the Great Depression - but not nearly as sharply as prices. Those workers who managed to keep their jobs - the
majority of workers - were living quite well. Keynes is quite right that wage rates are
simply not as elastic as other prices.
Keynes points out that a rise in prices relative to wages will create an increased demand
for labor that is frequently satisfied without any increase in money-wages. This is proof
8/14/2019 Keynes theories
http://slidepdf.com/reader/full/keynes-theories 10/34
that involuntary unemployment existed from which such demand could be satisfied. "[If]
the classical theory is only applicable to the case of full employment, it is fallacious to
apply it to the problems of involuntary unemployment" which in 1935 was everywhere.
Keynes, however, does not dispute that real wages - that price levels - "are uniquely
correlated" to volume of output, so that an increase in employment can only occur in theshort run if accompanied by a decline in real wages as prices move higher and increase
the demand for labor. However, prices may decline - causing an increase in real wages (as
they did during the Great Depression). Thus, "a willingness on the part of labour toaccept lower money-wages is not necessarily a remedy for unemployment." (Indubitably,
there are many factors other than prices and wages that impact labor markets.)
Then, Keynes provides this remarkable segment:
"The pitfalls of a pseudo-mathematical method, which can make no progress except by
making everything a function of a single variable and assuming that all the partial
differentials vanish, could not be better illustrated. For it is no good to admit later on thatthere are in fact other variables, and yet to proceed without re-writing everything that has
been written up to that point."
As Keynes candidly points out elsewhere, this can be said for ALL macroeconomic
econometric models - those even with multiple variables - no matter how complex theymay be.
"A scientific theory cannot require the facts to conform to its own assumptions," Keynes
states with profound wisdom. It must explain observable reality. Keynes properly
pummels Pigou's work on this basis.
Keynes himself fails to provide work that meets this basic requirement. However, to hisgreat credit, he candidly attaches suitable warnings of imprecision to his own macro-
econometric analyses - and even to some of his non-econometric work - warnings that his
followers would generally disregard.
Then, Keynes touches on a point related to weaknesses in his own approach.
"Professor Pigou has altogether omitted from his analysis the unstable factor, namely
fluctuations in the scale of investment, which is most often at the bottom of the
phenomenon of fluctuations in employment."
The reasons why investment levels fluctuate are many and varied. Except for thegeneralized over-optimism that afflicts prosperous times, and the fears that accompany
periods of distress, Keynes omits or grossly oversimplifies them.
The Problem With Savings:

8/14/2019 Keynes theories
http://slidepdf.com/reader/full/keynes-theories 12/34
The element based on idle supplies and equipment is minimized or intentionally omitted
by other theorists. However, Keynes insists that it has relevance - most noticeable for
inventories of consumable supplies like copper. The importance of this factor increaseswhen conditions of surplus and idleness are expected to last for significant periods.
Everything but land or some precious commodities during inflationary times will become obsolete or deteriorate over time or incur carrying or opportunity costs ultimately
in excess of its value, rendering this element of very minimal importance, indeed. For example, the price of copper declined sharply during the first three years of the Great
Depression, resulting in massive forced sales of surplus inventories.
The entrepreneur's profit and factor costs together are the total income for the
entrepreneur and his employees.
The profit - which Keynes refers to as "the income" - of the entrepreneur is the excess
of the proceeds over factor and user costs. The entrepreneur's profit and factor coststogether are the total income for the entrepreneur and his employees.
With costs of the supply of employment thus defined, Keynes provides a supply and
demand schedule for his "General Theory" based on the intersection of aggregate proceeds of employment and aggregate costs of the employment that achieves those
proceeds. He uses the phrase "aggregate supply function" for the former and "aggregate
demand function" for the latter. The point of intersection is "the effective demand for labor."
Keynes uses this term - "effective demand" - to distinguish it from previous theories
of labor supply and demand that assumed that the market would always clear at a point
that could be defined as full employment. "Says Law" - "supply creates its own demand"
- is a prominent feature of such views.
Labor market theories are based on competitive markets. When markets are disturbed
because of ordinary excess - such as various "bubbles" in the private sector - the periods
of increased unemployment can reasonably be attributed to temporarily increased levelsof frictional unemployment while those excesses are sorted out under the pressures of
economic decline. Such periods of economic decline are generally less than three years in
duration.
It is when inappropriate private monopoly or cartel polices or government policies
stubbornly resist such sorting out that labor markets fail. Conditions of involuntaryunemployment can then last for a decade. Indeed, they can and do last indefinitely.
8/14/2019 Keynes theories
http://slidepdf.com/reader/full/keynes-theories 13/34
It is thus more accurate to say that traditional labor market theory is indeed "general" - but only for economic systems and their labor markets that are reasonably flexible and
competitive and subject to reasonably competent government policies. During the Great
Depression, and during the chronic inflation and stagflation of the 1970s, that was
definitely not the case.
Says Law has its problems - but it was never presumed to operate outside reasonably
competitive markets operating in economic systems subject to reasonable government policies.
When income increases, so does "the propensity to consume." However, the latter increases somewhat less than the former, according to Keynes, "since when our income
increases our consumption increases also, but not by so much."
Keynes then explains his theory of employment.
"When employment increases, aggregate real income is increased. The psychology of
the community is such that when aggregate real income is increased aggregateconsumption is increased, but not by so much as income. Hence, employers would make
a loss if the whole of the increased employment were to be devoted to satisfying the
increased demand for immediate consumption. Thus, to justify any given amount of
employment there must be an amount of current investment sufficient to absorb theexcess of total output over what the community chooses to consume when employment is
at the given level. For unless there is this amount of investment, the receipts of the
entrepreneurs will be less than is required to induce them to offer the given amount of employment. It follows, therefore, that, given what we shall call the community's
propensity to consume, the equilibrium level of employment, i.e. the level at which there
is no inducement to employers as a whole either to expand or to contract employment,will depend on the amount of current investment. The amount of current investment will
depend, in turn, on what we shall call the inducement to invest; and the inducement to
invest will be found to depend on the relation between the schedule of the marginal
efficiency of capital and the complex of rates of interest on loans of various maturitiesand risks."
Then he asserts his key argument.
"[There] is no reason in general for expecting that [the point of equilibrium will] beequal to full employment."
"The effective demand associated with full employment is a special case, only realised
when the propensity to consume and the inducement to invest stand in a particular
relationship to one another. This particular relationship, which corresponds to theassumptions of the classical theory, is in a sense an optimum relationship. But it can only
8/14/2019 Keynes theories
http://slidepdf.com/reader/full/keynes-theories 14/34
exist when, by accident or design, current investment provides an amount of demand just
equal to the excess of the aggregate supply price of the output resulting from full
employment over what the community will choose to spend on consumption when it isfully employed."
However, during prosperous times, investment levels generally run AHEAD of savings - pushing interest rates and prices higher in a familiar cyclical pattern as businesses
compete for savings and productive resources that are at such times always in SHORTsupply. Keynes amazingly attributes this last surge in interest rates to "fear." In fact, such
surges occur when optimism reigns supreme - "irrational exuberance" - and a lack of
caution is in fact the predominant characteristic.
During times of prosperity, everybody keeps their savings in banks - for superior
security and convenience as well as for some interest earnings - and the financingmechanism never has any trouble putting ALL savings to work in commerce. When
doubts arise, they strike equity values long before they begin to undermine a modern
financial system. So Keynes fails to explain how periods of prosperity initially break down.
When income increases, so does "the propensity to consume." However, the latter
increases somewhat less than the former, according to Keynes, "since when our income
increases our consumption increases also, but not by so much."
The greater the volume of employment, "the greater will be the gap" between aggregate
income and aggregate consumption that must be filled by investment to retain its stability. Whenever investment does not so rise, full employment cannot be maintained.
This "psychological law" is the key to the problem. The greater the volume of
employment, "the greater will be the gap" between aggregate income and aggregate
consumption that must be filled by investment to retain its stability. Whenever investmentdoes not so rise, full employment cannot be maintained.
"The propensity to consume and the rate of new investment determine between them the
volume of employment, and the volume of employment is uniquely related to a given
level of real wage -- not the other way around. If the propensity to consume and the rate
of new investment result in a deficient effective demand, the actual level of employmentwill fall short of the supply of labour potentially available at the existing real wage, and
the equilibrium real wage will be greater than the marginal disutility of the equilibriumlevel of employment."
8/14/2019 Keynes theories
http://slidepdf.com/reader/full/keynes-theories 15/34
"The insufficiency of effective demand will inhibit the process of production in spite of the fact that the marginal product of labour still exceeds in value the marginal disutility of
employment."
"The richer the community, the wider will tend to be the gap between its actual and its
potential production; and therefore the more obvious and outrageous the defects of theeconomic system."
Thus, Keynes derives his overall reason for economic dislocations. It has definiteMarxian overtones - that he acknowledges in a footnote.
"This analysis supplies us with an explanation of the paradox of poverty in the midst of
plenty. For the mere existence of an insufficiency of effective demand may, and often
will, bring the increase of employment to a standstill before a level of full employment
has been reached. The insufficiency of effective demand will inhibit the process of production in spite of the fact that the marginal product of labour still exceeds in value
the marginal disutility of employment.
"Moreover the richer the community, the wider will tend to be the gap between its actual
and its potential production; and therefore the more obvious and outrageous the defects of the economic system. For a poor community will be prone to consume by far the greater
part of its output, so that a very modest measure of investment will be sufficient to
provide full employment; whereas a wealthy community will have to discover muchampler opportunities for investment if the saving propensities of its wealthier members
are to be compatible with the employment of its poorer members. If in a potentially
wealthy community the inducement to invest is weak, then in spite of its potential wealth,the working of the principle of effective demand will compel it to reduce its actual
output, until, in spite of its potential wealth, it has become so poor that its surplus over its
consumption is sufficiently diminished to correspond to the weakness of the inducement
to invest.
"But worse still. Not only is the marginal propensity to consume weaker in a wealthy
community, but, owing to its accumulation of capital being already larger, theopportunities for further investment are less attractive unless the rate of interest falls at a
sufficiently rapid rate; which brings us to the theory of the rate of interest and to the
reasons why it does not automatically fall to the appropriate level, which [is covered later
in the book]."
Marx himself could not have written a more bleak picture of the fate of "mature"
capitalist economic systems. However, why, then, is there observably more
unemployment - and more intractable conditions of unemployment - in so many poor countries?
And how convenient this theory is. It relieves the Keynesians - again like the Marxists -
8/14/2019 Keynes theories
http://slidepdf.com/reader/full/keynes-theories 16/34
of the chore of analyzing the particular causes of particular periods of economic decline.
It is all, after all, just a function of mature capitalist systems - a weakness inherent in
capitalism - just as Marx said.
Keynes then acidly criticizes Ricardo and subsequent classical economic theorists for
insisting on a theory that observably doesn't explain the facts of the business cycle -resulting at last in the hopelessness of the Great Depression.
In this Keynes is clearly correct. Classical theory indeed doesn't explain the business
cycle. It doesn't deal with the factors of private and government excess and inappropriate policy that can temporarily or permanently undermine competitive markets. However,
Adam Smith wrote of several such factors that were thus recognized a century and a half
before Keynes was writing his General Theory. See, HYPERLINK

Income, Savings, and Investment
Income:
Keynes defines the "income" of an entrepreneur as total revenue minus use of
inventory, wear and tear of productive assets - including productive equipment andfacilities - and also minus sums paid to other entrepreneurs. Calculations for discreet
periods include appropriate adjustments for inventory and productive assets at the
beginning and end of the period.
Wages and salaries paid are income to their recipients, but are balanced by theresulting changes in the value of inventories and other assets for the entrepreneur.
Inventory values are based on market exchange values - making this a much broader and
defensible application of the labor theory of value than that of Marx.
The determination of equipment and facilities costs is one of the key problems faced
by Keynes. He here applies his "user cost" concept - deducting the value of the facilities

with maintenance and improvements reasonable under the economic circumstances. He
provides a simplistic econometric formula for the calculation to "measure the sacrifice of
value involved in production" of output.
This is clearly an indeterminate figure. Moreover, except for things with very low
carrying costs - like land and precious substances - it is probably a negative figure. Highreal interest rates will tend to make the figure for even land and precious substances a
negative figure. Keynes later recognizes the impact of carrying costs. Use it or lose it!
A - U, revenues minus user costs, is the aggregate income of the economy.
Payments to other entrepreneurs for all other purposes are "factor costs." Both
factor and user costs are income to others. User costs plus factor costs equal the "primecost of output," which is deducted from revenues to determine "income."
"Income" is thus "gross profit." This is what the entrepreneur "endeavors to maximize -
- - [a concept] which agrees with common sense."
With this convenient simplification, Keynes can boil down the entire income of thenation to the "value" of production minus total user costs. Value is measured by revenues
- exchange values - rather than by the indeterminate industrial labor use-values of Marx.
A - U, revenues minus user costs, is the aggregate income of the economy.
"Income, thus defined, is a completely unambiguous quantity." (Keynes here overlooksthe ambiguities inherent in the inexact arts of the accountant, including such inherent
ambiguities as calculations of wear and tear and depreciation, and the value of private businesses as going concerns, and the value of sweat equity and human know-how.)
Since the entrepreneur "endeavors to maximize" his income - which is his gross profit -his expectation of such income determines "how much employment to give to other
factors of production." "[It] is the quantity which is causally significant for employment."
• Aggregate consumption is thus the exchange value of aggregate production
minus factor costs: Σ(A -A1).
• Aggregate investment is thus aggregate factor costs minus user costs: Σ(A1 -U).
• User costs are "the individual entrepreneur's disinvestment" - and the sums paid
to cover user costs are his investment - "in respect of his own equipmentexclusive of what he buys from other entrepreneurs."
• Consumption - in a completely integrated system - without international
commerce - thus equals the exchange value of output, and investment equals user costs.

Thus, since income is equal to aggregate sales minus aggregate user costs - and
aggregate consumption is equal to aggregate sales minus aggregate transactions between
entrepreneurs, savings must be equal to aggregate transactions between entrepreneurs
minus aggregate user costs; or Σ
(A1 -U). For "net savings," aggregate supplemental costshave to also be deducted; or Σ( A1 -U -V).
Aggregate income that people decide not to consume or invest is "savings."
Current investment - "the current addition to the value of the capital equipment which
has resulted from the productive activity of the period" - is equal to savings as defined
above. Omitting the Σ for convenience, Keynes summarizes aggregative elements as
follows:
"We have seen above that as the result of the production of any period entrepreneurs endup with having sold finished output having a value A and with a capital equipment which
has suffered a deterioration measured by U - or an improvement measured by -U where U
is negative - as a result of having produced and parted with A, after allowing for purchases A1 from other entrepreneurs. During the same period finished output having a
value A -A1 will have passed into consumption. The excess of A -U over A -A1, namely A1
-U, is the addition to capital equipment as a result of the productive activities of the
period and is, therefore, the investment of the period. Similarly A1 -U -V, which is the net
addition to capital equipment, after allowing for normal impairment in the value of
capital apart from its being used and apart from windfall changes in the value of the
equipment chargeable to capital account, is the net investment of the period."
Those "windfall changes," of course, are happening all the time in the markets, and canhave dramatic impacts on purchasing power and on all economic activities. Failure is a
substantial factor that Keynes does not include. There are always investments that fail
with substantial losses, and capital destroyed by the continuing processes of creativedestruction. On the other hand, the value of going concerns is generally greater than the
value of their physical assets.
Thus:
"Income = value of output = consumption +investment.Saving = income -consumption.
Therefore, saving = investment."
Aggregate income that people decide not to consume or invest is "savings."

Psychological Propensities and Inducements
Factors affecting consumption levels:
Aggregate consumption levels depend on certain objective and certain subjective
factors.
The accumulation of government surpluses as "sinking funds" to pay debts - or for anyother reason - can result in "severe contractions" of effective demand, according to
Keynes. Deficit spending by governments can result in "marked expansion" of effective
demand.
• Real wages - wages adjusted for price inflation or deflation - determine
consumption levels more than money-wages. Like Adam Smith, Keynes
determines purchasing power by the amount of labor - measured by Keynes in basic "wage-units" - obtainable in the market. If these wage-units change,
consumption will change in the same direction, but to a somewhat less extent
relative to given levels of employment. This may be altered somewhat by changesin income distribution between entrepreneurs, rentiers and labor.
• It is net income that affects consumption. Changes in income not reflected in net
income won't impact consumption.• Windfall changes in capital values - like securities and real estate price
fluctuations - will impact the propensity to consume.
"The consumption of the wealth-owning class may be extremely susceptible to
unforeseen changes in the money-value of its wealth. This should be classified amongst
the major factors capable of causing short-period changes in the propensity to consume."
Yet another similarity with the views of Karl Marx. Wealth and the consumption of
"luxury" goods increases instability in capitalist systems, according to both Marx and
Keynes. However, this is not evident in the historic record. The greatest periods of 20thcentury instability - the 1930s and 1970s - were clearly caused by colossal stupidity in
government policies, not by factors inherent in the private sector of wealthy nations. See,
HYPERLINK "http://www.futurecasts.com/Depression_mythology-I.html" \t "_top"

µUnderstanding Inflation§."
• Changes in real interest rates and perceived economic and financial risk levels
will impact the propensity to consume. This is more important for longer term
tendencies rather than short term tendencies unless the changes are fairly sharp.
Short term fluctuations are likely to be overlooked by most people. However,
capital asset values do respond more sensitively and immediately to changes inthese factors and thus provide a more immediate indirect influence on
consumption tendencies.
8/14/2019 Keynes theories
http://slidepdf.com/reader/full/keynes-theories 21/34
• Changes in "fiscal policy" - in taxation and government spending - have an
obvious impact. The accumulation of government surpluses as "sinking funds" to
pay debts - or for any other reason - can result in "severe contractions" of effective demand, according to Keynes. Deficit spending by governments can
result in "marked expansion" of effective demand.
Somehow, this has never been demonstrated in actual practice. The WW-II experience -
widely cited as proof - is seriously flawed. For some reason, economic history is litteredwith instances of economic crises caused or worsened by government indebtedness.
• Expectations of future earnings growth or decline may also impact
consumption levels. However, this is probably more important for individual
consumption than aggregate consumption, since changes will probably averageout, with aggregate changes occurring only slowly over extended periods.
This is probably in error. Even when wage levels remain stationary, individuals
generally expect future income to be greater than current income. The onset of arecession can have a dramatic impact, here, as can the onset of recovery.
As long as the wage-unit in terms of money remains fairly stable, Keynes points out,
the propensity to consume will likely remain fairly stable.
"Windfall changes in capital-values will be capable of changing the propensity to
consume, and substantial changes in the rate of interest and in fiscal policy may make
some difference; but the other objective factors which might affect it, whilst they must
not be overlooked, are not likely to be important in ordinary circumstances."
It is changes in the volume of output and employment that most impact aggregate
consumption tendencies.
The savings gap:
Consumption tendencies adjust to income fluctuations but to lesser degrees and with
some delay.
Wealthy societies will save more than poor societies since immediate needs of the poor will require greater proportionate levels of spending. "These reasons will lead, as a rule,
to a greater proportion of income being saved as real income increases."
8/14/2019 Keynes theories
http://slidepdf.com/reader/full/keynes-theories 22/34
"For since consumers will spend less than the increase in aggregate supply price whenemployment is increased, the increased employment will prove unprofitable unless there
is an increase in investment to fill the gap."
Thus, savings will fluctuate with income fluctuations, but more in the short term than
in the long term. Cyclical fluctuations thus have a marked impact on savings rates.
"Thus, a rising income will often be accompanied by increased saving, and a falling
income by decreased saving, on a greater scale at first than subsequently."
Wealthy societies will save more than poor societies since immediate needs of the poor
will require greater proportionate levels of spending. "These reasons will lead, as a rule,
to a greater proportion of income being saved as real income increases."
Except for economic systems that cannot get above subsistence levels, this has not beenthe case. In fact, savings rates in the wealthiest nations - like the U.S. - have been in
notorious decline for decades, while savings rates remain high in nations still only
marginally beyond subsistence levels.
A major factor in the business cycle, according to Keynes, is thus the tendency of consumption increases and decreases to be proportionately less than corresponding
income increases and decreases. Thus, Keynes focuses on this mythological savings
"gap."
"For since consumers will spend less than the increase in aggregate supply price when
employment is increased, the increased employment will prove unprofitable unless thereis an increase in investment to fill the gap."
Somehow, the statistics generally fail to support this fundamental Keynesian conclusion.
Not only have savings rates been in notorious decline in recent U.S. history, they evendeclined substantially in the last full year before the Great Depression - during the great
surge of prosperity between mid 1928 and mid 1929. This savings decline was
accompanied by a substantial decline in the number of savings accounts. These were thefirst declines since WW-I. Keynes is clearly writing in response to Great Depression
phenomena - but fails to acknowledge, much less explain, this inconvenient fact.
By accumulating funds for future investments or emergencies, the dreaded savings "gap"
is expanded and the investments that might fill the "gap" are delayed.
Like Marx, Keynes points an accusing finger at financial reserves. By accumulating
funds for future investments or emergencies, the dreaded savings "gap" is expanded and
the investments that might fill the "gap" are delayed. Such reserves constitute "a drag on
8/14/2019 Keynes theories
http://slidepdf.com/reader/full/keynes-theories 23/34
employment" during periods of accumulation - "suddenly made good in a lump" when
the reserves are expended for the intended investment or emergency. (This stupidity could
have been lifted straight out of Das Kapital.)
"Thus sinking funds, etc., are apt to withdraw spending power from the consumer long
before the demand for expenditure on replacements - which such provisions areanticipating - comes into play; i.e. they diminish the current effective demand and only
increase it in the year in which the replacement is actually made. If the effect of this isaggravated by 'financial prudence,' i.e. by its being thought advisable to 'write off' the
initial cost more rapidly than the equipment actually wears out, the cumulative result may
be very serious indeed."
Then, Keynes provides these remarkably inaccurate sentences:
"In the United States, for example, by 1929 the rapid capital expansion of the previous
five years had led cumulatively to the setting up of sinking funds and depreciation
allowances, in respect of plant which did not need replacement, on so huge a scale that anenormous volume of entirely new investment was required merely to absorb these
financial provisions; and it became almost hopeless to find still more new investment on
a sufficient scale to provide for such new saving as a wealthy community in full
employment would be disposed to set aside. This factor alone was probably sufficient tocause a slump."
If there were so much excess savings, why were interest rates so high in 1929?
Investment demand was expanding exuberantly - clearly outrunning available savings
and pushing interest rates high enough to draw substantial funds from as far away asEurope. All types of debt - consumer as well as investment - expanded sharply well into
October, 1929.
While interest rates declined rapidly AFTER economic contraction began in August of
1929, the decline was from extraordinarily high levels and did not reach nearly normal
levels until economic decline became obvious in October, 1929. Indeed, they did notreach levels indicating a lack of investment demand for all available funds until many
months thereafter.
On a more logically firm footing, Keynes points to the problems of excess savings in1935 - in the midst of the Great Depression, when there was little profit inducement to
borrow the accumulated savings. He belabors government "prudence" in accumulating
sinking funds for future needs. The data Keynes relies on for this point - admittedly less than precise - also shows that
"net capital formation" remained high through 1929, and did not decline until thereafter -
after the Great Depression had already begun. The decline thus was the result of theslump - not its cause.
8/14/2019 Keynes theories
http://slidepdf.com/reader/full/keynes-theories 24/34
Keynes remarkably views the increase in capital in wealthy states as a problem rather
than as a strength.
"Each time we secure to-day's equilibrium by increased investment we are aggravating
the difficulty of securing equilibrium to-morrow."
Only if interest rates are managed so as to maintain levels of full employment do the
classical models hold and savings retain their status as virtues.
Prudence and savings thus come under sharp attack by Keynes.
"We cannot, as a community, provide for future consumption by financial expedients but
only by current physical output."
The terminology is different, but the fallacy is the same as that of Karl Marx.
Keynes remarkably views the increase in capital in wealthy states as a problem rather than as a strength.
True, the business cycle naturally involves tendencies to periodically over-expand
capital assets and inventories during prosperous periods. Periods of irrational exuberance
during prosperous times is a general factor in the business cycle properly recognized byall economists - including Marx and Keynes. Working these excesses off during periods
of economic decline poses obvious difficulties. Nevertheless, this is a short term problem
that is routinely dealt with during the ordinary business cycle - involving periods of decline of about three years or less. It is not the long term problem that Keynes is talking
about.
According to Keynes - and Marx - as savings increase for wealthy states, investment
must also consistently increase to circulate those savings and avoid secular economicdecline - a task that gets increasingly difficult in the face of a growing abundance of
capital assets.
"Thus the problem of providing that new capital-investment shall always outrun capital-
disinvestment sufficiently to fill the gap between net income and consumption, presents a problem which is increasingly difficult as capital increases. New capital-investment can
only take place in excess of current capital-disinvestment if future expenditure on
consumption is expected to increase. Each time we secure to-day's equilibrium byincreased investment we are aggravating the difficulty of securing equilibrium to-
8/14/2019 Keynes theories
http://slidepdf.com/reader/full/keynes-theories 25/34
morrow. A diminished propensity to consume to-day can only be accommodated to the
public advantage if an increased propensity to consume is expected to exist some day."
Keynes - writing during the Great Depression - clearly views the nation's livingstandards as ultimately static. His mind - thus little better than that of Marx - is incapable
of contemplating the constantly increasing standards of living of the 20th century, oncethe trade wars and financial obstacles of the Great Depression were removed.
Keynes fails to understand that widely accumulated assets - especially private homes -
would DECREASE the need for private savings. Businesses, too, would be able to rely
on the equity values of assets and businesses as going concerns as a substitute for savings. Thus, wealthy states with well developed and secure financial systems would
have far less need for high savings rates than less developed nations.
The propensity to save itself declines with the accumulation of capital and durable
assets. Anyone who has bought and furnished homes knows there are no natural limits to
the propensity to consume.
Fluctuations in income are the greatest influence on short-period changes inconsumption. Thus, substantial increases in interest rates actually reduce savings because
of the extent that they reduce economic activity, investment and incomes. Thus, "a rise in
the rate of interest must have the effect of reducing incomes to a level at which saving isdecreased in the same measure as investment." The more we try to save under such
circumstances, the worse it gets.
"The more virtuous we are, the more determinedly thrifty, the more obstinately orthodox
in our national and personal finance, the more our incomes will have to fall when interest
rises relatively to the marginal efficiency of capital. Obstinacy can bring only a penalty,not a reward. For the result is inevitable."
Only if interest rates are managed so as to maintain levels of full employment do the
classical models hold and savings retain their status as virtues.
The multiplier:
A rise in the rate of investment tends to increase employment by more than the sumsinvested, and a fall tends to similarly decrease employment.
In the normal case, "small fluctuations in investment will lead to wide fluctuations in
employment."
8/14/2019 Keynes theories
http://slidepdf.com/reader/full/keynes-theories 26/34
Inflation need be of no concern, since true inflation occurs only with full employment.
The existing propensity to consume changes only slowly in normal circumstances.
Given the existing propensity to consume, a given level of investment will not only resultin the obvious amount of employment - called "primary employment" - but will also
result in additional employment as a result of the consumption activities of those
primarily employed.
This is a "multiplier" factor that can be precisely calculated depending on the existing
"marginal propensity to consume" (which cannot be precisely calculated). Keynes provides a simple mathematical formula for determining the extent to which increases in
employment with a given level of capital equipment will result in further consumption
and employment. This same calculation can explain the further growth of employmentthat will flow from a given level of investment - the "investment multiplier."
Thus, if the community tends to consume - say - nine-tenths of any income increment,
the multiplier will be 10 - and that will hold as good for public works as for privateinvestment as long as the former doesn't displace the latter. (If it does, real wages will
decline due to the significantly lower productivity levels in the government sector.)
Thus, in the normal case, "small fluctuations in investment will lead to wide fluctuations
in employment." The amount of additional investment that will produce full employment
is thus small or large depending on the marginal propensity to consume the additionalincome flowing from increased rates of investment. Inflation need be of no concern, since
true inflation occurs only with full employment.
This is a common Keynesian assertion refuted by centuries of economic history as well
as subsequent experience with Keynesian policies during the stagflation period of the1970s.
Offsets:
Applied to public policy - to changes in expenditures for public works - various offsets
must be taken into account.
• Increased borrowing that pushes up interest rates, or increases in taxation, will
reduce the multiplier impacts of an increase in public works. Any rise in the costof capital goods due to the additional demand will reduce their marginal
efficiency for private investors. Thus, interest rates must not only be kept steady,
8/14/2019 Keynes theories
http://slidepdf.com/reader/full/keynes-theories 27/34
they must be pushed down, if increases in public works are to have their full
multiplier impact.
Deficit spending thus doesn't increase employment when the financial system is in tact.It is the monetization of debt to keep interest rates down that normally provides all the
actual stimulus.
• "Confused psychology" that causes loss of confidence in the private sector as a
result of increases in government works financed by deficits and the expansion of the money supply may produce negative impacts. This may increase savings -
"liquidity preference" - for contingency reserves, or diminish the marginal
efficiency of capital and thus private investment.
It may ultimately also cause capital flight and decapitalization as assets are milkedrather than maintained.
•
Foreign trade reduces the multiplier for domestic employment. The artificialconsumption and investment of Keynesian policies will increase imports - only a
minor fraction of which will be recouped as foreign economic systems respond.
This obvious negative impact on the balance of trade and international payments would be determinedly ignored by Keynesians, who would express amazement at the collapse of
the dollar in the 1970s after a decade of Keynesian policy implementation. Today, again,
Keynesian policies are accompanied by chronic currency devaluation.
• As full employment is thus maintained, the marginal propensity to consume
will tend to decline as real incomes increase.
Yet again, Keynes repeats that ridiculous Marxian notion of the weaknesses of "mature"
wealthy economic systems.
• To the extent that public works increase entrepreneurial profits rather than
labor wages, the multiplier will be reduced due to the lower propensity toconsume of the former.
But won't higher profits increase the inducement to invest, with even a higher multiplier
impact?
•The reduction in "negative savings" as the newly employed stop consumingtheir own savings or those of others will increase aggregate savings rates and
reduce the multiplier.
But won't this decrease - or limit the increase - of interest rates?
8/14/2019 Keynes theories
http://slidepdf.com/reader/full/keynes-theories 28/34
Closed economic systems are thus more amenable to Keynesian manipulation. Keynes
estimates that modern communities tend to consume about 80% of additional income,
providing a multiplier of about 5. However, if foreign trade "accounts for, say, 20% of consumption and where the unemployed receive out of loans or their equivalent up to,
say, 50% of their normal consumption when in work, the multiplier may fall as low as 2
or 3 times" the primary employment.
This, according to Keynes, is why employment fluctuated so much more in the U.S.
than in Great Britain during the first years of the Great Depression.
Foreign trade in the U.S. - artificially restrained by trade war protectionism andnaturally limited by the greater extent of the U.S. market - was proportionally much
smaller than in England.
Even unwise public works will more than pay for themselves during periods of severeunemployment.
The multiplier is not instantaneous. Its impacts are gradual. If the change in
investment rates is large and abrupt, various immediate impacts will cloud the picture
until the multiplier has its logical results.
When unemployment is high, the multiplier for increased investment or public works is
highest due to the higher propensity to consume. Thus, even unwise public works willmore than pay for themselves during periods of severe unemployment.
"Pyramid-building, earthquakes, even wars may serve to increase wealth, if theeducation of our statesmen on the principles of the classical economics stands in the way
of anything better."
Bush (II) could have used Keynes for a speech writer. Somehow, the major increases in
public works during the 1930s failed to end the Great Depression. Somehow, vast deficits
failed to end Japan's economic malaise during the 1990s. Somehow, numerous nationshave suffered financial collapse despite all the benefits of their vast deficits. Somehow,
the U.S. is rewarded with a chronically devaluing currency and the corresponding adverse
shift in its terms of trade as a result of all the "benefits" of its current vast deficits and
rapidly expanding money supply.
The inducement to invest:
Expected yields and current interest rates determine investment rates. Keynes
properly emphasizes expected yields rather than just current yields in drawing his
8/14/2019 Keynes theories
http://slidepdf.com/reader/full/keynes-theories 29/34
8/14/2019 Keynes theories
http://slidepdf.com/reader/full/keynes-theories 30/34
However, real interest rates at or near zero in the 1970s did not prevent the onset of
stagflation in the U.S. - with double digit levels of inflation and nearly double digit levels
of unemployment at the same time.
Keynes explains the business cycle in terms of a broad theory, "the fluctuations of
the marginal efficiency of capital relative to the rate of interest." Although the theories aresomewhat different, this is quite similar to the approach of Karl Marx. It enables them
both to ignore all the particular factors that contribute to particular periods of economic
distress.
These sorts of games are quite common in economics. There are always infinite chains
of cause and effect in operation, and anything can be "proved" to be a substantive cause
by merely choosing where along the chain to begin the examination. Keynes candidly
admits that his choices of independent variables are not based just on their merits, but onthe basis of whether he believes that they can be conveniently manipulated.
The risk-reward ratio is properly brought into the picture at this point. Keynesdiscusses perceptions of risks both for borrowers and lenders, and the tendency of such
perceptions to decline to "unusually and imprudently low" levels during periods of
prosperity.
Prospective yield:
The state of confidence is a key factor in the evaluation of long term prospects,Keynes properly emphasizes. It is one of the "major factors" determining the investment
demand-schedule. Unfortunately, unlike other major factors - like the rate of interest - it
is very uncertain and nebulous.
Unless investors believed in - or strongly hoped for - success, they would not risk what
they have on the uncertain future.
Businessmen and investors are inherently optimistic, Keynes wisely recognizes.
Unless they believed in - or strongly hoped for - success, they would not risk what they
have on the uncertain future. Nor is this only a matter of profit.
"If human nature felt no temptation to take a chance, no satisfaction - profit apart - inconstructing a factory, a railway, a mine or a farm, there might not be much investment
merely as a result of cold calculation. - - - The actual results of an investment over a long
8/14/2019 Keynes theories
http://slidepdf.com/reader/full/keynes-theories 31/34
term of years very seldom agree with the initial expectation." (Yet another viewpoint
twisted by the experience of the Great Depression!)
The liquidity of the market provides support for investor confidence by reducing the great uncertainties of a long period into the much lesser uncertainties of a continuous succession of short periods. Liquidity thus facilitates the raising of capital.
Stock exchanges make investments liquid - facilitating the raising of capital, as wellas directing the allocation of capital. However, this liquidity also increases the volatility
of capital asset values.
Market valuation provides vital guidance on the basis of an implicit assumption that it is"uniquely correct in relation to the existing knowledge of the facts which will influence
the yield of the investment, and that it will only change in proportion to changes in this
knowledge." However, this is an obvious fiction. Such knowledge is neither precise nor unmitigated by many other operative factors. However, the liquidity of the market
provides support for investor confidence by reducing the great uncertainties of a long
period into the much lesser uncertainties of a continuous succession of short periods.Liquidity thus facilitates the raising of capital.
Keynes points out several factors that serve to undermine investor confidence.
• Stock market investors lack the insiders knowledge of how a business is actually
doing.
• Short term fluctuations in profits can have extraordinary impacts on stock
valuations.• Lack of knowledge renders market investors prey to substantial fluctuations in
mass psychology that may be totally unrelated to prospective yield.
• Professional market traders make matters worse by concentrating on unstable
factors of short term valuation.• Conditions in either the stock markets or the financial sector may cause a collapse
of investment demand - but confidence must recover in both sectors for recovery
of investment demand.
The volatility in stock markets is entirely appropriate, since the capital traded in these
markets - equity capital - is the risk capital of the economy. It is flexible and thus able to
absorb the winds of change.
If there is a substantial base of equity capital, it will suitably shield the vast mass of debtcapital, which can thus be comparatively stable. This is vital, since debt capital is
inflexible and will suffer total failure under strain.
Even more stable is the human capital of the nation. Human capital will survive for
8/14/2019 Keynes theories
http://slidepdf.com/reader/full/keynes-theories 32/34
decades, even during catastrophic conflicts. It took seven decades of autocratic socialism
to thoroughly destroy the human capital in the Soviet Union.
"[There] is no such thing as liquidity of investment for the community as a whole."
Keynes views Wall Street as dominated by speculative interests - rather than investment interests. The markets seem to him as acting like casinos. The culprit is market liquidity.
Keynes thus launches into a famous rant against market speculation and "the fetish of liquidity." (Marx, too, liked to invoke the concept of "fetish" to demean economic factors
that he wished to disregard.)
"[There] is no such thing as liquidity of investment for the community as a whole. The
social object of skilled investment should be to defeat the dark forces of time andignorance which envelop the future."
Who should society turn to to challenge these "dark forces" in the market? In fact, there
are very few investors or investment advisers who prove themselves capable of beating
the market averages over the long haul.
Writing from the despair of the depths of the Great Depression, Keynes laments that
long term investors face greater difficulties due to the greater risks inherent in long term
prospects. A large measure of the investment that does exist is due to the "animal spirits"- the impulse towards action - of entrepreneurs and investors, since nobody can truly
calculate the long term risks and prospects of enterprise.
"There is no clear evidence from experience that the investment policy which is socially
advantageous coincides with that which is most profitable."
Once free of the government policy stupidities that caused the Great Depression duringthe 1930s - the trade wars and vast defaulted debts from WW-I and thereafter - such
evidence of the superiority of long term investments would become abundant. Those long
term risks would be dispelled by acknowledgement of the long term vigor and productivity of the U.S. economic system which would increasingly prosper whenever
not too encumbered by government policies of gross stupidity. In nations like the U.S.
that enjoy the marvelous benefits of capitalism, only optimism pays.
Of course, Marxists and Keynesians would be too mired in despair over the
mythological difficulties of "mature" economic systems to notice. The imminent return of
the Great Depression would be a persistent element of their economic expectations.
8/14/2019 Keynes theories
http://slidepdf.com/reader/full/keynes-theories 33/34
Nevertheless, Keynes does score some valid points, here. Institutional investors must
justify their performance for each year and even for each quarter, glorifying short term
results over long term results. Fund managers adopt the conventional wisdom of their peers rather than risk error on the basis of personal analysis.
With the recent experience of the 1929 boom and bust, Keynes views Wall Street asdominated by speculative interests - rather than investment interests. The markets seem to
him as acting like casinos. The culprit is market liquidity.
"This is the dilemma," Keynes laments. Only the liquidity of the equity markets attract the
vast sums of equity capital on which the financial stability of the economy rests.
Keynes advises an increase in transaction costs by means of a stock transfer tax to
reduce this liquidity and speculation. That this would increase the costs of raising equitycapital does not escape Keynes' notice. "This is the dilemma," he laments. Only the
liquidity of the equity markets attract the vast sums of equity capital on which the
financial stability of the economy rests.
Keynes is probably unaware that all the speculative excess of 1929 was concentrated in
about 50 speculative leaders on the NYSE. As for the rest, there were as many losers as
gainers in the year prior to October, 1929. Such speculation is certainly a problem, but
not of such extent as could justify the limitation of liquidity for the vast bulk of themarket.
The crisis of confidence the afflicts the Great Depression world can only be cured by theradical idea of forcing people to either consume or invest their funds.
Keynes is thus driven to a remarkable radical conclusion. The crisis of confidencethat afflicts the Great Depression world can only be cured by forcing people to either
consume or invest their funds. The "hoarding" of funds that Keynes believed to be the
cause of the crisis might then be ended.
Again, this Marxian stupidity afflicts Keynes.
Idle savings were a result of the Great Depression, not its cause.
