As the nominal interest rate cannot fall below zero, a central bank with imperfect credibility faces a significant challenge to stabilize the economy in a New Keynesian model during a large recession. We characterize the optimal monetary policy at the zero lower bound for the nominal interest...

When the nominal interest rate reaches its zero lower bound, credibility is crucial for conducting forward guidance. We determine optimal policy in a New Keynesian model when the central bank has imperfect credibility and cannot set the nominal interest rate below zero. In our model, an...

The considerable amount of research in recent years on New Keynesian, open-economy models -- models with nominal price rigidities and intertemporally maximizing agents -- has yielded fresh insights for what Alan Blinder has called the "dark art" of making monetary policy. The literature has made...

Early in 2000, after a decade of economic expansion, growth began to slow simultaneously in the large, advanced economies known as the Group of Seven (G-7)--Canada, France, Germany, Italy, Japan, the United Kingdom, and the United States. The general slide in GDP growth fueled speculation that a...

This paper investigates breaks in the variability and comovement of output, consumption, and investment in the G-7 economies. In contrast with most other papers on comovement, we test for changes in comovement, allowing for breaks in mean and variance. Despite claims that rising integration...

This paper examines periods of pronounced rises and falls of real house prices since 1970 in eighteen major industrial countries, with particular focus on the lessons for monetary policy. We find that real house prices are pro-cyclical—comoving with real GDP, consumption, investment, CPI...

In measuring the percentage of foreign-held U.S., German, and Swiss currencies for the period of the 1960s through the 1990s, I obtain estimates much different from those of others. Using currency demand equations implied by cointegrating vectors for Canada, the Netherlands, and Austria, I...

This paper investigates breaks in the variability and co-movement of output, consumption, and investment in the G-7 economies. In contrast with most other papers on co-movement, we test for changes in co-movement allowing for breaks in mean and variance. Despite claims that rising integration...

In this paper we provide two building blocks for an analysis of international policy coordination: (1) a survey of models of policy coordination, and (2) an account of experience with policy coordination among the G-7 countries and within Europe since the breakdown of the Bretton Woods System....
