The Mengerian Vision

The Mengerian Vision
The Austrian school is best known for its microeconomics and, in particular,
for its role in the marginalist revolution. In the early 1870s, Carl Menger,
along with French economist Léon Walras and English economist William
Stanley Jevons, reoriented value theory by calling attention to the marginal
unit of a good as key to our understanding the determination of the good’s
market price. With marginality central to the analysis, microeconomics was
forever changed. It is less widely recognized, however, that a viable macroeconomic
construction also arises quite naturally out of the marginalist
revolution in the context of Menger’s vision of a capital-using market economy.
Modern macroeconomics makes a distinction between factor markets (inputs)
and product markets (outputs). Intermediate inputs and outputs are
rarely in play. By contrast, the economics of the Austrian school features a
production process – a sequence of activities in which the outputs associated
with some activities feed in as inputs to subsequent activities. The eventual
yield of consumable output constitutes the end of the sequence. Menger
(1981 [1871]) set out the theory in terms of ‘orders of goods’, the first, or
lowest, order constituting consumer goods and second, third and higher orders
constituting producers’ goods increasingly remote in time from goods of
the lowest order. Eugen von Böhm-Bawerk (1959 [1889]) introduced the
similar notion of ‘maturity classes’ to capture this temporal element in the
economy’s production process. He stressed the point that an increase in the
economy’s growth rate must entail an increase in activity in the earlier maturity
classes relative to (concurrent) activity in the later maturity classes.

Böhm-Bawerk was possibly the first economist to insist that propositions
about the macroeconomy have firm microeconomic foundations. In an 1895
essay, he wrote that ‘One cannot eschew studying the microcosm if one
wants to understand properly the macrocosm of a developed economy’
(Hennings, 1997, p. 74). Ludwig von Mises (1953 [1912]), who is generally
credited for using marginal utility analysis to account for the value of money,
was also the first to recognize the significance of credit creation in the context
of a decentralized, time-consuming production process. The capital theory
originated by Menger and the theory of money and credit set out by Mises
were developed by Friedrich Hayek (1967 [1935]) into the Austrian theory of
the business cycle. Lionel Robbins (1971 [1934]) and Murray Rothbard
(1963) applied the theory to the interwar episode of boom and bust. Eventually,
the insights of these and other Austrians gave rise to a full-fledged
capital-based macroeconomics (Horwitz, 2000 and Garrison, 2001; see also
Littlechild, 1990).
