We study the effects of model uncertainty in a simple New-Keynesian model using robust control techniques. Due to the simple model structure, we are able to find closed-form solutions for the robust control problem, analysing both instrument rules and targeting rules under different timing...

This paper studies how a central bank’s preference for robustness against model misspecification affects the design of monetary policy in a New-Keynesian model of a small open economy. Due to the simple model structure, we are able to solve analytically solve the optimal robust policy rule,...

The emergence of the New Consensus in monetary policy has been followed by a renewal of interest in central banks’ operating procedures, and specifically in the role of open market operations. There is a general view that overnight interest rates are most effectively controlled by standing or...

Monetary policy transmission lags create credibility problems for the inflation-targeting policy maker who acts under discretion. We show that if prices react to monetary policy with a longer lag than output, the welfare maximizing inflationtargeting policy implies no policy stabilization of...

In this paper, we examine the incentives for central bank activism and caution in a two-country open-economy model with uncertainty and learning. We find that the presence of a strategic interaction between the home and foreign central banks creates an additional motivation for caution in...

We examine global dynamics under infinite-horizon learning in New Keynesian models where monetary policy practices either pricelevel or nominal GDP targeting and compare these regimes to inflation targeting. These interest-rate rules are subject to the zero lower bound. Robustness of the three...

We examine global dynamics under infinite-horizon learning in New Keynesian models where the interest-rate rule is subject to the zero lower bound. As in Evans, Guse and Honkapohja (2008), the intended steady state is locally but not globally stable. Unstable deflationary paths emerge after...

We use the ten years of experience in inflation-targeting in New Zealand since 1989 to test whether monetary policy appears to conform to the simple rules that have been recommended for it in the literature. Of the inflation targeting central banks, the Reserve Bank of New Zealand has both the...

This paper investigates the consequences of introducing endogenous price stickiness into a standard monetary policy model. We find that the modification reduces the optimal degree of inflation stabilization to which the central bank should commit. The reason is that less inflation stabilization...

We examine global economic dynamics under infinite-horizon learning in a New Keynesian model in which the interest-rate rule is subject to the zero lower bound. As in Evans, Guse and Honkapohja, European Economic Review (2008), we find that under normal monetary and fiscal policy the intended...
