Standard macro models cannot explain why real exchange rates are volatile and disconnected from macro aggregates. Recent research argues that models with persistent growth rate shocks and recursive preferences can solve that puzzle. I show that this result is highly sensitive to the structure of...

This paper is structured in three parts. The first part outlines the methodological steps, involving both theoretical and empirical work, for assessing whether an observed allocation of resources across countries is efficient. The second part applies the methodology to the long-run allocation of...

During the last two decades, the degree of openness of national financial systems has increased substantially. At the same time, asymmetries in information and other financial market frictions have remain prevalent. We study both empirically and theoretically the implications of the opening up...

Conventional wisdom suggests that financial liberalization can help countries insure against idiosyncratic risk. There is little evidence, however, that countries have increased risk sharing despite recent widespread financial liberalization. This work shows that the key to understanding this...

An often heard view is that exchange rate variability will decrease for a country that joins the EMU. This is not necessarily true. Both real and nominal exchange rate variability increase under certain circumstances when asymmetric demand shocks occur inside or outside the union. These results...

This paper presents an eclectic model that systematizes the dynamics of self-fulfilling crises, using the main aspects of the three typologies of third generation models, to describe the stylized facts that hasten the withdrawal of a pegged exchange rate system. The most striking contributions...

This paper develops a NATREX (NATural Real EXchange rate) model for two large economies, the Eurozone and the United States. The NATREX approach has already been adopted to explain the medium-long term dynamics of the real exchange rate in a number of industrial countries. So far, however, it...
