Expectational and Portfolio-Demand Shifts in a Keynesian Model of Monetary Growth Fluctuations

Abstract

We develop a pair of models to show how non-ad-hoc shifts to expectational variables can be used to model tendencies toward crisis. In the Shackle model, as developed in the book Keynesian Kaleidics (1974), uncertainty can lead to a collapse in the marginal efficiency of investment and a jump in liquidity preference. In the Minsky version of the model, excessive private debt can lead to a financial collapse–again an endogenous breakdown in forces supporting growth. We extend the models to indicate how the dynamics of inflation and distribution affect the dynamics.
