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...

Here we investigate the selection of an optimal horizon for inflation targeting in the United Kingdom. We examine each of several ways for interpreting optimal horizons. To assess robustness against model uncertainty, we derive results for a set of models „ rather than just one „ having...

This paper uses a DSGE model to study the potential benefits and costs of joining a monetary union. We show that the potential benefits arise from two sources. First, it reduces the magnitude of shocks by eliminating shocks to the nominal exchange rate, which have been found to be very...

We build a small open-economy model with partial financial dollarization--households hold wealth in domestic currency and a foreign currency; firms also have a balance sheet mismatch as in Gertler, Gilchrist and Natalucci (2001). The degree of dollarization is endogenous to the extent of...

The most popular simple rules, due to Taylor (1993) and McCallum (1995), are both meant to inform monetary policy in economies that are closed. On the other hand, their main open economy alternative, the Monetary Conditions Index (MCI) rule of Ball (1999) is flawed for a number or reasons, not...

Abstract: The literature on the New Phillips Curve (NPC) started off with an analysis of pricing behaviour in economies that are closed and with price and wage contracts that are either of the Calvo or Taylor-style. In the spirit of the Batini, Jackson and Nickell (2000) here we focus on the...
