A Dynamic Equilibrium Model of Inflation and Unemployment

A stochastic general equilibrium model is constructed which is capable of examining the covariance properties between inflation and unemployment, both conditioned and unconditioned upon the state of exogenous real and monetary factors. Indivisibilities introduced into agents' labor choice decisions produce unemployment in equilibrium. It is shown that indigenous forces in a competitive economy can result in the traditional negative relationship between inflation and unemployment. The policymaker, while perhaps observing a negatively sloped Phillips curve, actually faces Fdedman's positively sloped one.
