We study the conduct of monetary policy in a continuum of small open economies and obtain a novel closed-form solution that does not restrict the elasticity of substitution between home and foreign goods to one. We give an exact characterization of optimal monetary policy and welfare with and...

There is growing empirical evidence that the strength of the cost channel of monetary policy differs across countries. Using a New Keynesian model of a two-country monetary union, we show how the introduction of a cost channel (differential) alters the optimal monetary responses to union-wide...

This paper develops a two-country multi-frictional model where the freeze on liquidity access to commercial banks in one country raises unemployment rates via credit rationing in both countries. The expenditure-switching channel, whereby asymmetric monetary shocks traditionally lead to negative...

This study examines the feasibility of international monetary policy coordination among the ASEAN-5 + 3 countries using the two-production-factor dynamic stochastic general equilibrium (DGSE) model. It explores three types of interaction regimes among these countries: "no coordination,"...

Over the last decade a new consensus model has emerged in monetary macroeconomics, labelled New Keynesian macroeconomics (Clarida et al., 1999). It consists of three simple building blocs: a forward-looking IS-equation that is derived from the optimization problem of a representative household,...

This paper evaluates the welfare implications of policy rules when international financial markets are incomplete. Using a two-country dynamic general equilibrium model with incomplete markets, price stickiness and monopolistic competition, one finds that an allocation in which the producer...

This paper examines the policy challenges a country faces when it wants to both reduce inflation and maintain a sustainable external position. Mundell's (1962) policy assignment framework suggests that these two goals may be mutually incompatible unless monetary and fiscal policies are properly...

A positive and normative evaluation of alternative monetary policy regimes is addressed in a simple two-country general equilibrium model. The behavior of the exchange rate, as well as of the other macroeconomic variables, depends crucially on the monetary regime chosen, though not necessarily...

We establish the share of exports in production as a sufficient statistic for optimal non-cooperative monetary policy. Under financial autarky, markups positively co-move with the export share. For complete markets, markups should be procyclical if the export share is procyclical. When central...

We study international monetary policy spillovers and spillbacks in a tractable two-country Heterogeneous Agent New Keynesian model. Relative to Representative Agent (RANK) models, our framework introduces a precautionary-savings channel, as households in both countries face uninsurable income...
