Mundell (1973) argues that a common currency area provides benefits for its members by offering insurance against region-specific shocks. We develop a simple model to analyse the nature of risksharing benefits of a single currency area for emerging market economies, based on Mundell's...

This paper develops an analytical model to evaluate the costs and benefits of a single currency area within a unified framework, inspired by the separate arguments of Mundell (1961) and (1973). The more familiar argument is that, in the presence of country-specific shocks, a single currency area...

The paper evaluates the costs and benefits of a single currency area within a unified framework. Conventionally, it is argued that a single currency area carries a welfare loss owing to the sacrifice of exchange rate adjustment in the presence of country-specific shocks. But in 1973 Mundell...

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...

Monetary rules may have a large effect on the outcome of trade wars if central banks target the CPI inflation rate or more generally changes in the relative price of traded goods. We lay out a two-country open-economy model with sticky prices where countries engage in trade wars. In the presence...

This paper studies the interaction between foreign exchange reserves and the currency composition of sovereign debt in emerging countries. Focusing on inflation targeting countries, we find that holdings of foreign reserves are associated with higher local currency sovereign debt, an exchange...

This paper explores the implications of the European single currency within a simple sticky price intertemporal model. The main issue we focus on is how the euro may alter the responsiveness of consumer prices to exchange rate changes. Our central conjectures is that the acceptance of the euro...

This article explores the implications of the European single currency within a simple sticky price intertemporal model. We focus on the question of how the euro may change the sensitivity of consumer prices in Europe to exchange-rate changes. Our central conjecture is that the acceptance of the...
