More on Prices in the Real World

One can see many ways in which prices are set in the real world, from volatile prices on speculative, secondary financial asset markets and primary commodity markets, to auction markets, and to the haggling that can occur in bazaars and street markets, especially for second hand goods.

But a fundamental empirical observation about many markets for newly produced goods and services, especially in industrial markets, is that prices are administered or set by corporations and businesses, according to normal production costs plus a profit markup.

Some observations on this follow:
(1) often business leave their prices unchanged for significant periods of time, from three months to a year, despite changes in demand (Gu and Lee 2012: 462). When prices are adjusted this is the result of changes in factor input costs, including raw materials and labour. Changes in the profit markup result from competition and need for profit.

(2) The profit markup is itself often stable as well, which leads to some degree of stability of profits that results from price administration (Gu and Lee 2012: 461). Stable profits in turn allow stable margins for internal financing of investment (Melmiès 2012).

(3) the advantages of price setting to businesses include the reduction of the occurrence of price wars, goodwill relationships with customers, and stable selling costs (Gu and Lee 2012: 461).

(4) empirical studies show that, outside given limits, businesses find that variations in their set prices produce no significant change in sales volume, and, above all, when prices are cut, this does not necessarily lead to changes in short term market sales (Gu and Lee 2012: 462). And experiments with prices adjusted downwards to a significant extent show that this causes a severe blow to profits, so severe indeed that enterprises quickly abandon all such experiments (Gu and Lee 2012: 461).

Is This What Vulgar Austrians Mean by “Economic Calculation”?

In a talk on April 9, 1975 that Hayek gave to the American Enterprise Institute in Washington DC, he made the following comment on the nature of the business cycle:
“These discrepancies of demand and supply in different industries, discrepancies between the distribution of demand and the allocation of the factors of production, are in the last analysis due to some distortion in the price system that has directed resources to false uses. It can be corrected only by making sure, first, that prices achieve what, somewhat misleadingly, we call an equilibrium structure, and second, that labor is reallocated according to these new prices.

Lacking such price readjustment and resource reallocation, the original unemployment may then spread by means of the mechanism I have discussed before, the “secondary contraction,” as I used to call it. In this way, unemployment may eventually become general.

The primary cause of the appearance of extensive unemployment, however, is a deviation of the actual structure of prices and wages from its equilibrium structure. Remember, please: that is the crucial concept. The point I want to make is that this equilibrium structure of prices is something which we cannot know beforehand because the only way to discover it is to give the market free play; by definition, therefore, the divergence of actual prices from the equilibrium structure is something that can never be statistically measured.” (Hayek 1975: 6–7).
This passage is recycled ad nauseum by certain Rothbardians such as “Bob Roddis,” with the astonishing comment that it contains “simple basic [sc. Austrian] concepts that … all the other anti-Austrians refuse to comprehend.” Speaking of this very quotation, that same Rothbardian declares:
“Like every other non-Austrian, you guys just do not understand the essential concept of economic calculation or the concept of the equilibrium price structure that does not yet exist.”

“[t]here is no essential dispute between Hayek, Mises, Rothbard, Lew Rockwell or me regarding the following which states the basic Austrian understanding of the economic galaxy” [my emphasis – LK].
But, on reading the Hayek quotation, one is struck by the fact that the central concept is the notion of a tendency to a price vector that will clear all markets (with flexible wages clearing the labour market). This is not an “Austrian” idea at all: it is a Walrasian or neo-Walrasian neoclassical idea, straight from general equilibrium theory. The Austrians did not invent this, but simply borrowed it from Walrasian neoclassicals.

A fundamental theoretical point of Post Keynesian economics – and indeed much heterodox economics in general – is the rejection of the notion of a market tendency to general equilibrium, with extensive arguments why there is no such tendency, owing to the presence of fundamental uncertainty, subjective expectations, the failure of Say’s law, the non-neutrality of money, and the falsity of the gross substitution axiom.

Here we have the most astonishing sight of vulgar internet Austrians complaining that the critics do not understand “basic Austrian” concepts, yet these same Austrians are unaware that the very concepts in question they invoke are nothing but mainstream neoclassical equilibrium fictions, which are held by all orthodox economists such as New Classicals, monetarists and (to some extent) even the New Keynesians.

And, more seriously, certain Austrians such as the radical subjectivists do even accept that idea of market tendency to general equilibrium. Other Austrians such as Rizzo and O’Driscoll have substituted the notion of “pattern coordination” for general equilibrium theory.

If this does not prove how absurd and ignorant is this type of internet Austrian, with their endless carping about “not understanding basic Austrian concepts,” then frankly nothing will.
