Macro effects of interest-sensitive aggregate supply

This paper investigates the implications of the negative effect of the real interest rate on aggregate supply. The micro foundations of this effect are first explained. The effect is then incorporated into a dynamic macro model with inflation and rational expectations. If the wealth effect on consumption is large, an increased interest sensitivity of aggregate supply enhances stability. If the wealth effect is small, increased interest sensitivity of supply is stabilizing up to a point, and destabilizing beyond that. Furthermore, an increased interest sensitivity of aggregate supply enhances the positive effect of the monetary growth rate upon steady-state output, and it enhances the negative effect of government spending upon steady-state output.
