Abstract

This paper tests “Bad Policy” Hypothesis which refers to the Great Moderation in the US. We examine this hypothesis by simulating model based impulse response functions for the both pre-Volcker period and post 1982 period. Deriving and simulating standard New Keynesian DSGE Model explicitly, we find that while post 1982 policy i.e. active policy, is consistent with the unique stable equilibrium characteristics; pre-Volcker or passive monetary policy generates equilibrium indeterminacy. Moreover, our simulated-impulse response functions show that the response of inflation and the output gap in post 82 period is weaker than the macroeconomic responses of the pre-Volcker period.
