Inflation in the U.S. rose in the 1970s and fell in the 1980s and 1990s. The conventional story attributes this pattern to changes in monetary policy. Policymakers made errors and learned from them. This article presents the story and existing alternatives that emphasize instead changes beyond...

This article characterizes the change in the nature of the money growth-inflation and unemployment-inflation relationships between the first and second halves of the twentieth century. The changes are substantial, and the authors discuss some of the implications for modeling inflation dynamics,...

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...

Central banks analyze a wide range of data to obtain better measures of underlying inflationary pressures. Factor models have widely been used to formalize this procedure. Using a dynamic factor model this paper develops a measure of underlying inflation (UIG) at time horizons of relevance for...

The author proposes an alternative measure of inflation that captures the intuition behind the use of "core" measures. Inflation is modeled as an unobserved factor affecting the components of an aggregate price index (including food and energy). The common component, estimated using Kalman...

This paper addresses whether the Friedman rule can be optimal in an economy in which the Tobin effect is operative. We present an overlapping generations economy with capital in which limited communication and stochastic relocation create an endogenous transaction role for fiat money. We assume...
