In dynamic stochastic welfare comparisons, a failure clearly to distinguish between risk aversion and intertemporal substitutability can result in misleading assessments of the impact of risk aversion on the welfare costs of consumption-risk changes. The problem arises in any setting in which...

The exchange-rate regime is often seen as constrained by the monetary policy trilemma, which imposes a stark tradeoff among exchange stability, monetary independence, and capital market openness. Yet the trilemma has not gone without challenge. Some (e.g., Calvo and Reinhart 2001, 2002) argue...

The central claim in this paper is that by explicitly introducing costs of international trade (narrowly, transport costs but more broadly, tariffs, nontariff barriers and other trade costs), one can go far toward explaining a great number of the main empirical puzzles that international...

Despite an abundance of cross-sectional, panel, and event studies, there is strikingly little convincing documentation of direct positive impacts of financial opening on the economic welfare levels or growth rates of developing countries. The econometric difficulties are similar to those that...

This paper explores the connection between the much-debated global current account imbalances of the past decade and the U.S. financial collapse. It argues that the connection is an intimate one, although nothing so simple as cause and effect. Instead, the imbalances were a primary symptom of...

This paper presents a simple diagrammatic analysis of an open economy's external adjustment process under habit-forming individual preferences. The exposition focuses on the consumption side and aims to make transparent the linkage among wealth, past consumption experience, and current...
