This paper considers the optimal degree of discretion in monetary policy when the central bank conducts policy based on its private information about the state of the economy and is unable to commit. Society seeks to maximize social welfare by imposing restrictions on the central bank's actions...

Time-inconsistency is an essential feature of many policy problems (Kydland and Prescott, 1977). This paper presents and compares three methods for computing Markov-perfect opti- mal policies in stochastic nonlinear business cycle models. The methods considered include value function iteration,...

Discretionary policymakers cannot manage private-sector expectations and cannot coordinate the actions of future policymakers. As a consequence, expectations traps and coordination failures can occur and multiple equilibria can arise. To utilize the explanatory power of models with multiple...

This paper studies the behavior of a central bank that seeks to conduct policy optimally while having imperfect credibility and harboring doubts about its model. Taking the Smets-Wouters model as the central banks approximating model, the papers main fi…ndings are as follows. First, a central...

Ball (1997) shows using a small closed economy model that nominal GDP targeting can lead to instability. This paper extends Ball's model to uncover the role inflation expectations play in generating this instability. By changing the process by which inflation expectations are formed in the...

We study the effects of optimized monetary policy in a semi-structural, estimated small open economy in situations where the policymaker has either complete or less than complete confidence in the model being free from misspecification errors. We use the robust control techniques developed by...

This Economic Letter summarizes the papers presented at a conference on "Fiscal and Monetary Policy" held at the Federal Reserve Bank of San Francisco on March 4 and 5, 2005.

This Economic Letter looks at the problems with the NKPC and discusses some alternatives that are increasingly being used to think about inflation and the monetary policy transmission mechanism.

Inflation targeting has been adopted by many central banks, but not by the U.S. Federal Reserve. Using an estimated New Keynesian business cycle model, I perform counterfactual simulations to consider how history might have unfolded if the Federal Reserve had adopted a form of flexible inflation...

Consumption-habits have become an integral component in new Keynesian models. However, consumption-habits can be modeled in a host of different ways and this diversity is reflected in the literature. I examine whether different approaches to modeling consumption habits have important...
