This paper analyzes the cost of disinflations under real wage rigidities in a micro-foundedNew Keynesian model. The consensus is that real wage rigidities can be a useful mechanismto induce the inflation persistence that is absent in the standard Calvo model...

What are liquidity crises? And what can be done to address them? This short paper brings together some personal reflections on this issue, largely based on previous work. In the process, it questions a number of commonly held beliefs that have become part of the conventional wisdom. The paper is...

The recent global financial crisis has led central banks to rely heavily on "unconventional" monetary policies. This alternative approach to policy has generated much discussion and a heated and at times confusing debate. The debate has been complicated by the use of different definitions and...

Over the past 15 years there has been remarkable progress in the specification and estimation of dynamic stochastic general equilibrium (DSGE) models. Central banks in developed and emerging market economies have become increasingly interested in their usefulness for policy analysis and...

This paper develops a theoretical model of dynamic decision-making of a monetarypolicy committee with heterogeneous members. It investigates the optimal transparency,and the optimal way of transmitting information of committees, by analysing the effectsdifferent communication strategies have on...

Existing work on wage bargaining (as exemplified by Cukierman and Lippi, 2001) typicallypredicts more aggressive wage setting under monetary union. This insight has not beenconfirmed by the EMU experience, which has been characterised by wage moderation,thereby eliciting criticism from Posen and...

This paper studies a overlapping generations economy with capital where limitedcommunication and stochastic relocation create an endogenous transactions role for…at money. We assume a production function with a knowledge-externality (Romer-style) that nests economies with endogenous growth (AK...

The Friedman rule, a widely studied prescription for monetary policy, is optimal inTownsend’s turnpike model of money; it is not so in the overlapping generations versionof his stochastic relocation model of money. We investigate these monetary models inthe light of this disparity. To that...

In this paper, we explore the connection between optimal monetary policy and heterogeneityamong agents. We study a standard monetary economy with two types of agents inwhich the stationary distribution of money holdings is non-degenerate. Sans type-specific fiscalpolicy, we show that the...

Inflation rates in a number of OECD follow a common trend over the past four decades: inflation starts out low in the 1960s, rises for a time before peaking in the 1970s or early 1980s, and then falls back to initial levels. This similarity in the behavior of trend inflation suggests that any...
