Resumen de La théorie autrichienne des cycles: une théorie de la récurrence des erreurs collectives d' anticipation
This paper offers an account of the recent development of Austrian Trade Cycle Theory. It focus on the theoretical contributions and argues that the Austrian's explanation of Trade Cycle is a theory of collective errors of expectations and of their recurrences. Austrian economists agree to explain the errors of individuals by the nationalization of money because it leads to an excess of money supply. Nevertheless, they disagree about the cause of this excess. Two explanations have been suggested. The first one measures the excess in relation with the demand of money. The second one evaluates the excess in relation with monetary saving. They agree, on the contrary, on the reasons of the recurrence of expectation errors and their uniformity. The theory of property rights explains the recurrence of expectation errors by the socialization of risk. The expectation theory explains the collective errors by the centralisation of expectations (big player hypothesis) on the central bank decisions. Therefore, the centralization of expectations explains the instability of market process.
