Recent data show substantial increases in the size of gross external asset and liability positions. The implications of these developments for optimal conduct of monetary policy are analyzed in a standard open economy model which is augmented to allow for endogenous portfolio choice. The model...

This paper examines demand spillovers in a two country open economy model to a demand shock newline (emanating from a single, source country) sufficiently large to push one or both countries into a liquidity trap. The zero lower bound on nominal interest rates keeps the central bank in the...

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...

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...

Historically, the world payments system has been dominated by a single currency accepted in the exchange of goods and assets among countries. In recent decades, the US dollar has played this role. The dollar acts as a 'vehicle currency' in the sense that agents in non-dollar economies will...

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 stabilising the exchange rate. The traditional approach maintains that exchange rate flexibility is desirable in the presence of real...

What does financial globalization imply for the design of monetary policy? Does the case for price stability change in an environment of large cross country gross asset holdings? This paper is concerned with the effects of monetary policy under endogenous international portfolio choice and...
