Non-Austrian Views of the Business Cycle View a Booming Economy as a Healthy One

Rothbard (1963), taking an Austrian school approach, describes the cause of the Great Depression as the result of malinvestment that occurred during the 1920s. Monetary expansion during the 1920s led to the boom period described by Mises and Hayek. The Keynesian explanation for the Depression is that aggregate demand declined, largely due to the volatility of investment demand that suffered a substantial reduction after the stock market crash of 1929. The monetarist explanation was that because of problems with the banking system, the money supply declined precipitously following the 1929 stock market crash, and that monetary contraction turned what would have been a much less severe recession into the Great Depression. 

The Austrian explanation distinguishes itself by tracing the causal factors back to malinvestment during the upturn in the cycle. The problems leading to the business cycle occur during the upturn, and the downturn is the recovery phase, during which dislocations occur as people reallocate their resources away from unsustainable uses, as Horwitz (2000) notes. The significance of malinvestment as a cause of the downturn naturally focuses attention on the importance of recognizing the heterogeneity of capital. The Keynesian, monetarist and more recent general equilibrium models of the business cycle do not see the causes as being created by malinvestment prior to the downturn because those models do not account for the heterogeneity of capital. Non-Austrian views of the business cycle view a booming economy as a healthy one, whereas the Austrian school sees the downturn as the inevitable consequence of malinvestment during the boom phase.
