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...

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...

Kocherlakota and Pistaferri (EJ, 2007) [KP] develop a model of a world economy with private-information Pareto optimal (PIPO) risk sharing; in that model, the real exchange rate tracks relative domestic/foreign cross-sectional distributions of consumption. KP claim that the PIPO model fits the...

In the data country portfolios are heavily biased toward domestic assets. Standard one-good international macro models predict that, due to the presence of non-diversifiable labor income risk, country portfolios should be heavily biased toward foreign assets; this discrepancy constitute the...
