In a standard New Keynesian model, a myopic central bank concerned with stabilizing inflation and changes in the output gap will implement a policy under discretion that replicates the optimal, timeless perspective, precommitment policy. By stabilizing output gap changes, the central bank...

This paper shows that the credibility gain from permanently committing to a fixed exchange rate by joining the European Monetary Union can outweigh the loss from giving up independent monetary policy. When the central bank enjoys only limited credibility a pegged exchange rate regime yields a...

We study the rejection of the expectations hypothesis within a New Keynesian business cycle model.Earlier research has shown that the Lucas general equilibrium asset pricing model can account for neither sign nor magnitude of average risk premia in forward prices, and is unable to explain...

Within a New Keynesian business cycle model, we study variables that are normally unobservable but are very important for the conduct of monetary policy, namely expected inflation and inflation risk premia. We solve the model using a third-order approximation that allows us to study time-varying...

In this paper, I evaluate the performance deterioration that occurs when the central bank employs an optimal targeting rule that is based on incorrect parameter values. I focus on two parameters — the degree of inflation inertia and the degree of price stickiness. I explicitly account for the...

In this paper, I revisit an old question in the analysis of monetary policy that was first studied by Rogoff (1985) - should central banks pursue objectives that differ systematically from social welfare? I investigate how the answer to this question is affected by the degree of transparency...

This text presents a comprehensive treatment of the most important topics in monetary economics, focusing on the primary models monetary economists have employed to address topics in theory and policy. It covers the basic theoretical approaches, shows how to do simulation work with the models,...
