We model transitional dynamics that emerge after the adoption of a new monetary policy rule. We assume that private agents learn about the new policy via Bayesian updating, and we study how learning affects the nature of the transition and the choice of a new rule. Temporarily explosive dynamics...

This paper proposes a new measure of core inflation and compares it with several existing measures. The new measure is adaptive and is designed to track sudden and persistent movements inflation, such as those arising from changes in monetary policy regimes. the adaptive measure is a superior...

The New Keynesian Phillips curve (NKPC) asserts that inflation depends on expectations of real marginal costs, but empirical research has shown that purely forward-looking versions of the model generate too little inflation persistence. In this paper, we offer a resolution of the persistence...

The foundation of the New Keynesian Phillips curve (NKPC) is a model of price setting with nominal rigidities that implies that the dynamics of inflation are well explained by the evolution of real marginal costs. In this paper, we analyze whether this is a structurally invariant relationship....

For a VAR with drifting coefficients and stochastic volatilities, the authors present posterior densities for several objects that are of interest for designing and evaluating monetary policy. These include measures of inflation persistence, the natural rate of unemployment, a core rate of...

This paper investigates the relation between inflation uncertainty and excess returns on stocks and bonds. It quantifies the effect of inflation uncertainty by comparing actual excess returns with those expected by a hypothetical naive investor who treats inflation forecasts as if they were...
