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...

In a financial system where balance sheets are continuously marked to market, asset price changes show up immediately in changes in net worth, and elicit responses from financial intermediaries, who adjust the size of their balance sheets. We document evidence that marked to market leverage is...

The unfolding financial turmoil in mature economies has prompted the official and private sectors to reconsider policies, business models and risk management practices. Regardless of its future evolution, it already threatens to become one of the defining economic moments of the 21st century....

Caplin & Leahy (1996) show that, when central bankers learn about theeconomy by observing its response to policy shock, cautious monetary policymay be ineffectual as private agents correctly anticipate that today's interestrate cuts are likely to be followed by future cuts. The central banker...

Recent theoretical work shows that changes in the volatility of inflation and/or unem-ployment affect equilibrium in°ation outcomes when the central banker's loss functionis asymmetric. We show that previous evidence offered in support of the propositionthat the volatility of unemployment helps...

Using a standard dynamic general equilibrium model, we show that the interaction of staggered nominal contracts with hyperbolic discounting leads to inflation having significant long-run effects on real variables...

This paper explores the influence of wage and price staggering on monetary persistence. Weshow that, for plausible parameter values, wage and price staggering are complementary ingenerating monetary persistence. We do so by proposing the new measure of "quantitativeinertia," after discussing...
