Carl Menger
and His Followers - The Major Contributions of the Austrian School
What are the major cornerstones of the Austrian School?
Subjectivism,
Individualism, Uncertainty (emphasis on knowledge), Processes vs. End States
(change)
Because of the emphasis on these cornerstones: METHODOLOGY: Why
are they "radical" - not in the mainstream?
1. Methodological
individualism:
Only individuals act -- and we study human action as economists.
Only individuals have purposes.
Purposeful human action -- individuals act
purposefully. They act to remove a "felt uneasiness" (von Mises).
2. Methodological subjectivism:
Individual's values, knowledge and understanding of history, of the physical
world and the way it works, expectations, plans of action, etc. are the
individual's own and may be and often are different from those of others.
Individuals respond to incentives based upon their
own subjective values, tastes, knowledge, etc.
Individual value, therefore, cannot be measured!
Not only is value subjective to the individual, what an individual values today,
he or she might not value tomorrow.
So people basically value something because it can
meet an end for that individual. One does not value a piece of bread for
its own sake, a person values it because the bread can fulfill an end (such as
"remove hunger" ).
So market prices reflect the values that people have
relative to the scarcity (or availability) of a good. As we have seen,
this is what Carl Menger added in the 1870s -- market prices were finally
understood.
3. Emphasis on Uncertainty (as the world
really is):
And individuals act in the world of uncertainty. That is why institutions that
decrease uncertainty are so important.
So what is relevant to an
individual's action and to another individual's understanding of that action is
not the physical reality surrounding the actor and the action, but the
subjective perceptions of that reality.
So human beings act purposefully -
they wish to attain ends or goals. Since they wish
to attain these goals, they must be valuable to them; accordingly they must have
values that govern choices. And again, these values are subjective to the individual.
Therefore, Austrian economists do not "assume away"
uncertainty and instead assume perfect knowledge (as many mainstream models do).
4. Processes vs. End States
All action in the real world, furthermore, must take
place through time; all action takes place in some present and is directed
toward the future (immediate or remote) attainment of an end. If all of a
person's desires could be instantaneously realized, there would be no reason for
him to act at all - and all action would stop.
But this is not the case -- action continues -
change takes place.
The emphasis on these cornerstones is why
Austrian economist not limit themselves to mathematics
in trying to understand social phenomena.
Math cannot capture a) subjectivism, b) change, c)
uncertainty as it is demonstrated through purposeful human action of
individuals.
As political scientist Bruno
Leoni and mathematician Eugenio Frola pointed out,
But the lack of
mathematical precision in ordinary language reflects
precisely the behavior of individual human beings in the
real world…. We might suspect that translation into
mathematical language by itself implies a suggested
transformation of human economic operators into virtual
robots.

It is hard to pull out just a few of the major
contributions (commentary) - but let's start with capital theory.
1. Austrian Capital Theory:
Here we have to start with
Eugen
von Boehm-Bawerk (1851-1914):
Boehm-Bawerk read Menger's Principles as a
student, and though he never studied under Menger, he quickly became an adherent
of his theories.
His main contributions:
1.
Time Preferences: In
this work, Natural Value, Boehm-Bawerk built upon the
time-preference ideas of Carl Menger, insisting that there is always a
difference in value between present goods and future goods of equal quality,
quantity, and form. Furthermore, the value of future goods diminishes as the
length of time necessary for their completion increases.
So people prefer something today vs. tomorrow generally speaking.
Boehm-Bawerk cited
three reasons for this difference in value.
a.
First of all, in a growing economy, the supply of goods will always be
larger in the future than it is in the present.
b.
Secondly, people have a tendency to underestimate their future needs due
to carelessness and shortsightedness.
c.
Finally, entrepreneurs would rather initiate production with goods
presently available, instead of waiting for future goods and delaying
production.
2.
Diminishing Marginal Utility and Time Preferences: related
to the time preferences issue, in Capital and Interest Bohm-Bawerk
discusses the famous example of the pioneer farmer faced with decisions about
the allocation of his sacks of grain among the various uses-as basic feed for
himself, his chickens and his parrots, and as an ingredient for making brandy.
The essence of Austrian (Menger’s) marginalism is conveyed with his telling
the story of what would happen if the farmer were to suffer the loss of one sack
of grain (poor parrots). Time preferences will also play a role in forming
the marginal utility (what people will choose to do without as something becomes
more scarce). This story and many variations on it, told many times
by textbook writers over the decades since, stand in contrast to the
twice-differentiable total-utility functions that evolved from William Stanley
Jevons' marginalism and the general-equilibrium equations that dominate in Leon
Walras'.
3.
Exploitation Theory Critiqued: Most significant in this early
work, and also related to his emphasis on time, is his devastating critique
of the exploitation theory, as espoused by Karl Marx and the Socialists we
talked about earlier. According to
Bohm-Bawerk, capitalists do not exploit workers; they accommodate workers-by
providing them with income well in advance of the revenue from the output they
helped to produce. He asked: "Is
there any justification for the payment of interest to the owners of
capital?" The justification, in his view, rests on his time preference
theory – a simple fact of reality to him: people value present goods more
highly than future goods of the same quantity and quality. Future goods trade at
a discount, or alternatively, present goods trade at a premium. The payment
of interest is a direct reflection of this intertemporal (through time) value
differential. This interest,
paid to capitalists, allows workers to receive income on a more timely basis
than would otherwise be possible. In
other words, workers get paid a defined wage today, whereas the capitalist must
wait until the product is sold, and also must bear the uncertainty of what it sells for
in order to earn anything.
4.
The Time Structure of Production:
Also related to 1-3, Böhm-Bawerk introduced his bull's-eye figure-a
pattern of concentric rings intended to depict the time-structure of production.
Production begins in the center with the use of the original means (land and
labor); the process emanates outward over time; and the final product emerges at
the outermost ring to satisfy the consumers' ultimate ends. Two bull's eye
figures appearing on consecutive pages are used to contrast a well-developed
economy with a less-well-developed one. This depiction can be seen as a
forerunner of the more straightforward representation of the means-ends
framework introduced by F. A. Hayek. The
Hayekian triangle, which is divided along the time axis into "stages of
production," corresponds closely with the bull's eye figure, which is
divided along the radius into "maturity classes."
Maturity reflecting different stages in the production process – each entering
the picture at different times.
The
question is: how do we coordinate these stages through time?
Though static by its
very construction, the bull's-eye figure, as well as the better known Hayekian
triangle, is intended to facilitate the analysis of change.
Hayek used this to
form the Hayekian triangle:
Lengthening of the
Capital Structure or "Roundaboutness": (Higher and Lower order goods):
The message is clear: An
expansion of the capital structure is not to be viewed as a simultaneous and
equiproportional increase in capital in each of the maturity classes; it is
to be viewed as a reallocation of capital among the maturity classes.
Overlooked by his predecessors and largely ignored by the modern mainstream,
this is the market mechanism that keeps the economy's intertemporal
production plans in line with the intertemporal preferences of consumers.
The significance of this market mechanism was at issue in his debate with John
B. Clark, who held that once capital is in place, the maintenance of capital is
automatic and that production and consumption are, in effect, simultaneous.
So for Austrian
economists:
Capital is a structure
(capital must "fit" together -- through time and with the representation of
consumer preferences). This all relates to interest rates and time
preferences.
Hayek, of course also added the element how
the rules of the game change or create the capital structure. These rules
include laws - but also culture. Therefore, capital from one economy is
not necessarily going to work in another country. And in fact, can do more
harm than good.
2. Economic Calculation: Most especially
Mises -- then followed up by Hayek.
Is Socialism Possible?
Remember first the definition
of socialism (which is why this term is used quite frequently in this
discussion):
Prior to Mises raising the
calculation problem in 1920, the critics of socialism concentrated on the
incentive problem:
According to many socialists –
the problem was due to the fact that man’s nature had been formed and could be
changed:
Although Mises talked about the
incentive issue – that was not his main point.
What Mises did
was to say, OK, assume there is no incentive problem (we have all become the
“socialism man”) – if that is the case, then will socialism be a successful
economic system. His answer was “no.”
Let’s look at his famous
writing, “Economic Calculation in the Socialist
Commonwealth” (1920):
Mises first talked about:
People usually talk about the
distribution of consumption goods in the Socialist Commonwealth.
Who
is to do the consuming and what is to be consumed by each? Socialists emphasize
equality in terms of consumer goods – we all have the same “equal” distribution.
But,
Mises said, this is of secondary importance. Can have exchange among
consumption goods under socialism within the narrow limits permitted.
But the major problem is that no production goods will ever be
exchanged and therefore it will be impossible to determine their monetary
value.
If
we can’t determine that – then the consumer goods to be distributed will be few
(there is no way of “economizing” on the use of resources and determined
haphazardly by planners – have nothing to do with the wants of the people.)
Money could never fill in a socialist
state the role it fills in a competitive society in determining the value of
production goods. Calculation in terms of money will be
impossible.
Hence—it then becomes “impossible in any socialist state to posit a connection
between the significance to the community of any type of labor and the
apportionment of the yield of the communal process of production.”
So
remember – labor is included here! What should people do? What should they
train to become? There are no answers in socialism.
The Limits of Monetary Calculations
1.
Money is no yard-stick of value!
Value is not measured in money, nor is price. They merely consist in
money.
Money
as an economic good is not a stable value – its value is determined by S
& D like any other commodity and subject to diminishing marginal utility.
But
these fluctuations are comparatively trivial in regard to its exchange
–relations.
(with “good” money)
2.
Monetary value does not include value
outside of exchange relations.
Money is the common denominator
that makes valuation comparisons possible –
For example: A resource is
“worth” this much (say $100,000) in market A and this much (say $200,000) in
market B – it is comparable. But these prices only arise out of exchange.
The human mind cannot orientate
itself properly among the bewildering mass of intermediate products and
potentialities of production. We must have some “aid to the human mind” for
deciding where resources should go.
And in order to gain this “aid”
– we need exchange – which means we need private property rights in the means of
production!
With private property everybody
is a consumer and everybody a producer … and thereby resources flow in
economically “correct” directions. Correct meaning – towards more highly valued
uses, not wasted.
A socialist economy will have
to be a static economy.
There is only groping in the dark! There is no
trial and error. There is no entrepreneurial discovery!
Conclusion
So Mises concludes that in
order to have a successful economy (where the basic necessities of life are
met), we must have:
Economic Calculation:
“the decision-making ability to allocate scarce capital resources among
competing uses.”
My friend Pete Boettke sums in up this way
(quote):
1.
Without private property rights in the
means of production, there will be no market for the means of production.
2.
Without a market for a means of
production, there will be no monetary prices established for the means of
production.
3.
Without monetary prices, reflecting
the relative scarcity of capital goods, economic decision makers will be unable
to rationally calculate the alternative uses of capital goods.
Mises (from Human Action):
“Every single step of entrepreneurial activities is subject to scrutiny by
monetary calculation. The premeditation of planned action becomes commercial
precalculation of expected costs and expected proceeds. The retrospective
establishment of the outcome of past action becomes accounting profits and
losses.”
So market prices in capital
goods (which we have already learned reflect the subjective value of individual
consumers) – determine the potential costs of production – which then determine
if a profit will be made or not.
Example: Under socialism –
imagine this scenario: the government owns all means of production. So it owns
a plant that makes hamburger patties. It also owns the ranches that produce the
cows, the truck company that transports the meat, etc.
The “planners” are trying to
decide if this is the best use of this plant - the best use of the trucks, of
the land that houses the cow ranch. All they can do is guess. So therefore,
they make hamburgers that nobody wants, and they don’t make hot dogs that a lot
of people want. They use these capital goods in unproductive ways – ways that
waste resources. Even to the point of not being able to meet the basic
necessities of life.
So this argument by Mises lead
to The Economic Calculation Debate
F. A. Hayek (1899-1992) vs. J.
M. Keynes (1883-1946)

"When the definitive
history of economic analysis during the 1930s comes to be
written, a leading character in the drama (it was quite a drama)
will be Professor Hayek. . . . It is hardly remembered that
there was a time when the new theories of Hayek were the
principal rival of the new theories of Keynes" (Sir John Hicks,
1967).
The First
Debate
Point: Hayek - the
fundamental problem with Keynes's economics was his failure to
understand the role that interest rates and capital structure
play in a market economy. Because of Keynes's use of
aggregate (collective) concepts, he failed to address
these issues adequately in A Treatise on Money (1930). Hayek
pointed out that Keynes's aggregation tended to redirect the
analytical focus of the economist away from examining how the
industrial structure of the economy emerged from the
economic choices of individuals.
Counter Point:
Keynes did not take kindly to Hayek's criticism. He responded at
first by attacking Hayek's book Prices and Production (1931).
Then Keynes claimed that he no longer believed what he had
written in A Treatise on Money, and turned his attention
to writing another book, The General Theory of Employment,
Interest, and Money (1936), which in time became the most
influential book on economic policy in the 20th century.
No Counter Point from Hayek:
Rather than attempting to criticize directly what Keynes
presented in his General Theory, Hayek turned his talents to
refining capital theory. Hayek said that part of the reason he
didn't respond to Keyne's General Theory was because Keynes was
always changing his mind -- so why take the time to write a
response when Keynes will probably change his mind later anyway.
Some historians of thought think that if Hayek had responded
to the General Theory -- history would have been very different?
By the end of the 1930s, Keynes's
brand of economics was on the rise. In the eyes of the public
Keynes had defeated Hayek. Hayek lost standing in the profession
and with students.
During this time, Hayek was also
involved in another grand debate in economic policy-the
socialist calculation debate, triggered by a 1920 article by
Mises which stated that socialism was technically impossible
because it would lack market prices (cited above).
The Economic Calculation
Debate - Main Question: To what extent can the economy be
successfully planned and manipulated by government planners?
Hayek: In a way, this was a continuation
of Hayek's arguments against Keynes for his "aggregates" -- but
also against his call for economic planning.
Again, the economics profession
and the intellectual community in general did not appreciate
Hayek's criticism.
"What is the problem we wish to solve when we try to
construct a rational economic order? On certain familiar
assumptions the answer is simple enough. If we possess all the
relevant information, if we can start out from a given system of
preferences, and if we command complete knowledge of available
means, the problem which remains is purely one of logic." F.
A. Hayek - The Use of Knowledge in Society.
Focus is on coordination -
how do coordination and economic order emerge from the
unintended consequences of millions of economic actors?
Emphasis on knowledge -
Dispersed economic agents have knowledge of time and
circumstances which cannot be fully aggregated or understood by
central planners. Government planners have a knowledge
problem.
". . . the knowledge of the
particular circumstances of time and place. It is with
respect to this that practically every individual has some
advantage over all others because he possesses unique
information of which beneficial use might be made, but of which
use can be made only if the decisions depending on it are left
to him or are made with his active cooperation." (The Use of
Knowledge in Society)
Two Kinds of
Knowledge in Society:
Scientific:
Individual knowledge of time and circumstances (dispersed
throughout society):
Can planners
possess the knowledge necessary to move resources to where they
are useful to people? Even move resources such that the
basic necessities of life are met? Is economic calculation
possible without market prices, profits and losses?
Emphasis on prices:
Informational role of prices - prices serve as a learning
mechanism which allows economic agents to economize on the
quantity of information they must process in making choices.
Emphasis on change: "If
we can agree that the economic problem of society is mainly one
of rapid adaptation to changes in the particular circumstances
of time and place, it would seem to follow that the ultimate
decisions must be left to the people who are familiar with these
circumstances, who know directly of the relevant changes and of
the resources immediately available to meet them." (The Use
of Knowledge in Society)
Incentive Issues:
Hayek pointed out that political agents will often face perverse
incentives -- in the absence of private ownership, political
agents will lack the incentive to allocate resources in an
economically efficient manner (where people can use them).
This is true even if they had the knowledge to do so - which
they do not.
Keynes:
Main work was The General Theory of
Employment, Interest and Money (1936) - Response to the
Great Depression and the "failure" of Classical economics.
Emphasis on demand - and the
psychological reasons to consume or to invest:
"When employment
increases, D1 [consumption] will increase, but not by so much as
D [change in income]; since when our income increases our
consumption increases also, but not by so much. The key to
our practical problem is to be found in this psychological law."
(The General Theory)
Emphasis on aggregates:
Looking at
aggregate demand - and how this demand can be manipulated by
government.
Was emphasis on uncertainty:
But the uncertainty was one of the decision makers. Should
they invest or not? Depends upon the expected rate of
profit -- which is uncertain, for example. There was not
an emphasis on the uncertainty of economic planners!
Really an entirely different way of
looking at the economy and what was important to our
understanding of it.
Summing Up: Keynes vs.
Hayek
The original question:
To what
extent can the economy be successfully planned and
manipulated by government planners?
Keynes:
Government planners can effectively manipulate the
economy as desired in order to overcome the "failures of
the market" due to inadequate demand - "psychological
law". Planners should be able to use
discretionary policy (at their discretion).
Hayek: Due to
the knowledge problem and incentive issues, government
planners will be ineffective when attempting to plan an
economy. Interventions will generate unintended
(bad) consequences.
