The Depression Represents an Adjustment Process; This Process Can, BUT NEED NOT, Be Accompanied by Deflation

Just at the time when Hayek had entered the scene as an economic theorist in Great Britain, the economies of the major industrial countries found themselves in the midst of what came to be known as the Great Depression, characterised by a slump in production, high rates of unemployment, and a all in prices accompanied by a shrinking circulation of money. As soon as the fall in prices made itself felt, a debate on the proper reaction in terms of monetary policy evolved, in particular on whether the authorities should respond with expansionist policies and relation. Indeed, policies for preventing and counteracting deflation appeared to follow from Hayek’s stance, too, as neutral money to a first approximation corresponded to a policy of stabilising monetary circulation. Yet, as is well known, Hayek—like most of the economists close to the Austrian school—refrained from any such proposals and was extremely cautious with regard to expansionist monetary policies. Therefore a crucial question to be addressed is how Hayek conceived of the phenomenon of deflation and why he remained so hostile to anti-deflation policies.

In order to answer this question it is necessary to reconstruct Hayek’s approach to deflation. To recapitulate, according to Hayek’s theory the crisis is caused by a maladjustment in the structure of production typically initiated by a credit boom, such that the period of production (representing the capitalistic structure of production) is lengthened beyond what can be sustained by the rate of voluntary savings. The necessary reallocation of resources and its consequences give rise to crisis and depression. Thus, the ‘primary’ cause of the crisis is a kind of ‘capital scarcity’ while the depression represents an adjustment process by which the capital structure is adapted. This process can, but need not, be accompanied by deflation. It is in this specific meaning that Hayek speaks of deflation as being ‘secondary’, for example, when referring to “these (in a methodological sense) secondary complications which arise during the depression”, or maintains that “the process of deflation represents only a secondary phenomenon”. It should also be clear that Hayek was propounding the definition of deflation then prevailing in Austrian circles, that is, deflation as a decrease in (the circulation of) money as opposed to the more common meaning of a decrease in prices (or the price level).
