This paper analyzes the value of communication in the implementation of monetary policy. The central bank is uncertain about the current state of the economy. Households and firms are uncertain about the statistical properties of aggregate variables, including nominal interest rates, and must...

Modern theory has delivered both the conservative central banker and the principal-agent approaches as rationales for the independence of the central bank. The principal-agent approach directs attention to the importance of both clearly defining the goals of the central bank and its command in...

The exchange rate has by 1984 become as central to United States economic policy discussions as it has long been in the rest of the world. In this paper we show how the standard closed-economy macroeconomic model -- the Phillips curve augmented IS-LM analysis -- has to be modified for the United...

A country that decides to fix its exchange rate thereby gives up control over its own inflation rate and the determination of the revenue received from seigniorage. If the country goes further and uses a foreign money, it loses all seigniorage. This paper uses an optimal inflation tax approach...

The paper examines the case for activist monetary policy. It accepts the view that expectations are formed rationally, but not the implication of flexible price, equilibrium, rational expectations models, that monetary policy cannot and should not be used to affect real magnitudes. The paper...

Monetary DSGE models are widely used because they fit the data well and they can be used to address important monetary policy questions. We provide a selective review of these developments. Policy analysis with DSGE models requires using data to assign numerical values to model parameters. The...

This paper analyzes the constraints imposed on monetary and fiscal policy design by expectations formation. Households and firms learn about the policy regime using historical data. Regime uncertainty substantially narrows, relative to a rational expectations analysis of the model, the menu of...

In the wake of the 1997-98 financial crises, interest rates in Asia were raised immediately, and then reduced sharply. We describe an environment in which this is the optimal monetary policy. The optimality of the immediate rise in the interest rate is an example of the theory of the second...

We evaluate the Friedman-Schwartz hypothesis that a more accommodative monetary policy could have greatly reduced the severity of the Great Depression. To do this, we first estimate a dynamic, general equilibrium model using data from the 1920s and 1930s. Although the model includes eight...
