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...

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...

Recent evidence on the effect of government spending shocks on consumption cannot be easily reconciled with existing optimizing business cycle models. We extend the standard New Keynesian model to allow for the presence of rule-of-thumb (non-Ricardian) consumers. We show how the interaction of...

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...

Galí (2014) showed that a monetary policy rule that raises interest rates in response to bubbles can paradoxically lead to larger bubbles. This comment shows that a central bank that wants to dampen bubbles can always do so by raising interest rates aggressively enough. This result is different...

This paper develops a welfare-based model of monetary policy in an open economy. We focus on the extent to which monetary policy should be employed in maintaining the exchange rate. The traditional approach maintains that exchange rate flexibility is desirable in the presence of real...

This paper studies monetary policy games in a two-period Mundell-Fleming model, under a regime of managed exchange rates. A regime of managed exchange rates is defined as one where exchange rates are pegged but bilateral parities can be changed from time to time. The paper argues that such a...

This paper considers the effects of monetary and fiscal policies in an optimizing model with capital accumulation and finite lives. An increase in monetary growth is no longer superneutral in a money-capital economy, but leads to a reduction in the real interest rate and increases in the capital...

This paper analyses the costs and benefits of European monetary unification. The benefits take the form of the reduction in exchange risk, equalization of interest rates, decline in relative price variability and general increase in economic efficiency likely to accompany unification. The costs...

This paper analyses and compares the effects of common demand and supply shocks on the setting of optimal monetary policies under a clean float, a managed exchange rate system (such as the EMS) and a monetary union, when welfare depends on unemployment and the cost of living. The results suggest...
