Neutrality and Non-Neutrality of Money In A Classical-Type Model

This paper modifies the simple classical model by introducing capacity utilization that varies across the course of the business cycle. By making the capacity usage a choice variable that turns out to be sensitive to changes in the price level, we show that the classical model loses its fundamental feature, namely the neutrality of money. In our generalized framework, a rise in money supply improves upon all the real variables if the economy suffers from excess capacity, as in recessions and depressions. We demonstrate that our model describes the various economic cross-currents during the Great Depression extremely well. Thus, monetary policy emerges with an activist role even in a generally classical setting.
