After liberalizing international transactions of financial assets, many countries experience large swings in asset prices, capital flows, and aggregate production. This paper studies how the adjustment to capital account liberalization depends upon the degree of development of a domestic...

In this article I provide a perspective on the current state of modern business cycle theory. This theory has developed from an application of the Arrow-Debreu general equilibrium framework to the neoclassical growth model. On the positive side, this approach is able to accommodate various...

In this paper we present a simple, theory-based measure of the variations in aggregate economic efficiency associated with business fluctuations. We decompose this indicator, which we refer to as the gap, into two constituent parts: a price markup and a wage markup, and show that the latter...

This paper reviews the recent literature on monetary policy rules. We exposit the monetary policy design problem within a simple baseline theoretical framework. We then consider the implications of adding various real world complications. Among other things, we show that the optimal policy...

We construct a measure of Euro area cyclical efficiency, following the approach developed in Galí, Gertler and López-Salido (2002). Our measure –which we call "the gap"– corresponds to the inverse of price over social marginal cost. Here we present a time series of this gap for the Euro...

This paper reports estimates of monetary policy reaction functions for two sets of countries: the G3 (Germany, Japan and the United States) and the E3 (France, Italy and the United Kingdom). It finds that since 1979 each of the G3 central banks has pursued an implicit form of inflation...

We develop a model in which innovations in an economy's growth potential are an important driving force of the business cycle. The frame- work shares the emphasis of the recent “new shock” literature on revisions of beliefs about the future as a source of fluctuations, but differs by tieing...
