Abstract

This essay reviews the arguments made for a New Austrian theory of business cycles by Tyler Cowen, based on risk analysis and assuming rational expectations. This contrasts with the Old Austrian view that questions measurable risk in economic analysis. The way risk is applied to analyze business cycles suffers from serious inconsistencies. The use of rational expectations is mistaken in the face of economic complexity as understood by the traditional Austrians. However, Cowen is commended for his open-mindedness, even as this leads him away from a strictly Austrian perspective.
