With integrated trade and financial markets, a collapse in aggregate demand in a large country can cause 'natural real interest rates' to fall below zero in all countries, giving rise to a global 'liquidity trap'. This paper explores the policy choices that maximize the joint welfare of all...

The 'International Policy Trilemma' refers to the constraint on independent monetary policy that is forced on a country which remains open to international financial markets and simultaneously pursues an exchange rate target. This paper shows that, in a global economy with open financial...

Open economy macro theory says that when a country is subject to idiosyncratic macro shocks, it should have its own currency and a flexible exchange rate. But recently in many countries policy rates have been pushed down close to the lower bound, limiting the ability of policy-makers to...

This paper develops an analytical framework for the analysis of targeting rules for monetary policy. We derive the optimal money supply rule and analyze the implications of other monetary rules including rules that target nominal GNP, the price level, the monetary growth rate and the...

This paper deals with the design of optimal monetary policy and with the interaction between the optimal degrees of wage indexation and foreign exchange intervention. The model is governed by the characteristics of the stochastic shocks which affect the economy and by the information set that...

In this paper we examine how monetary policy should respond to nominal exchange rates in a New Keynesian open economy model that allows for a non-trivial role for sterilised intervention. The paper develops the argument against the backdrop of the evolving policy-making environment of Asian...

The purpose of this paper is to determine whether a two-tier exchange rate regime is more effective than a fixed rate regime in increasing acountry's ability to pursue an independent monetary policy in the short run.The analysis compares adjustment to a monetary policy and to a devaluation in...

This paper develops a welfare-based model of monetary policy in an open economy. We focus on the extent to which monetary policy should be employed in maintaining the exchange rate. The traditional approach maintains that exchange rate flexibility is desirable in the presence of real...

This paper develops a unified framework for the analysis of wage indexation and monetary policy in the presence of supply shocks. We first present simple formulae for the optimal wage indexation rule and for the optimal money supply rule. In order to set the stage for an evaluation of departures...
