This paper discusses the optimal use of inflation forecasts in an inflation targeting setting with reaction and implementation lags. It distinguishes between the optimality of history-dependence versus forward-lookingness in monetary policymaking. It is shown that monetary policy strategy is...

We estimate the interdependence between US monetary policy and the S&P 500 using structural VAR methodology. A solution is proposed to the simultaneity problem of identifying monetary and stock price shocks by using a combination of short-run and long-run restrictions that maintains the...

We argue that the correct identification of monetary policy shocks in a vector autoregression requires that the identification scheme distinguishes between permanent and transitory monetary policy shocks. The permanent shocks reflect changes in the inflation target while the transitory shocks...

We use robust control techniques to study the effects of model uncertainty on monetary policy in an estimated, semi-structural, small-open-economy model of the U.K. Compared to the closed economy, the presence of an exchange rate channel for monetary policy not only produces new trade-offs for...

We analyze the performance and robustness of some common simple rules for monetary policy in a New-Keynesian open economy model under different assumptions about the exchange rate model. Adding the exchange rate to an optimized Taylor rule gives only small improvements in terms of economic...

The performance of a simple monetary policy rule, which does not rely on explicit information about the output gap but instead uses the change in the rate of inflation as a proxy for the output gap, is explored in a simple model of the US economy. The rule is found to outperform an optimised...

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...

Robust control allows policymakers to formulate policies that guard against model misspecification. The principal tools used to solve robust control problems are state-space methods (see Hansen and Sargent, 2006, and Giordani and Söderlind, 2004). In this paper we show that the structural-form...

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 for the optimal robust policy rule, and...
