We argue that inflation-targeting strategy in practice can be approximated with the interest rate responding to the unchanged-interest-rate forecast of inflation. We develop a method to derive unchanged-interest-rate forecasts in forward-looking models and evaluate the performance of the policy...

In this paper, I consider a simple model in which agents learn about the inflation target of a central bank over time by observing the policy instrument or inflation outcomes. Measuring credibility as the distance between the perceived target and the actual target, an increase in credibility is...

Uncertainty about the persistence of periods characterized by large price shocks is an important aspect of monetary policy. This type of uncertainty posed some difficulties for central banks in 2004. This paper formalizes the treatment of this type of uncertainty by solving an optimal control...

Monetary policy is sometimes formulated in terms of a target level of inflation, a fixed time horizon and a constant interest rate that is anticipated to achieve the target at the specified horizon. These requirements lead to constant interest rate (CIR) instrument rules. Using the standard New...

This paper studies the impact of monetary policy transparency on economic stability, when economic agents are boundedly rational. I first consider a simple class of microfunded general equilibrium models with nominal rigidities and learning. Under a transparent monetary regime, market...

In this paper we present an algorithm for continuous minimax problem where a quasi--Newton direction conditional on appropriate maximizers is used. The direction involves a quadratic subproblem to compute the minimum norm subgradient. An application of the algorithm to a monetary policy design...

We address robustness of inflation targeting rules in a New Keynesian model using two approaches. Firstly we use the Hansen-Sargent method, borrowed from the control theory literature, to design robust rules on the basis of the policymaker playing a game against malign nature. This welfare-based...
