Optimal Policy under Commitment and Price Level Stationarity

Abstract

This paper proposes a simple analytical method to determine the stationarity of an unnormalized variable from the solution to a normalized model i.e. a model whose variables must be expressed in relative terms or must be differenced for a solution to exist. The paper then applies the method to answer a question of interest to policy-makers: does optimal policy under commitment lead to stationarity in the price level? Unlike Gaspar, Smets, and Vestin (2007), the paper finds that optimal policy under commitment does not lead to price level stationarity in the Smets and Wouters (2003) model.
