In a Ricardian model with CES preferences and general distributions of industry efficiencies, the sources of the welfare gains from trade can be precisely decomposed into a selection and a reallocation effect. The former is the change in average efficiency due to the selection of industries that...

We analyze the foundations of the relationship between trade and average productivity in the Ricardian model. Under broad assumptions about the autarky distributions of industry productivities, trade openness raises average productivity. This is due to the selection effect of international...

We analyze the foundations of the relationship between trade and TFP in the Ricardian model. Under general assumptions about the autarky distributions of industry productivities, trade openness raises TFP. This is due to the selection effect of international competition --- driven by comparative...

We introduce a novel methodology to measure the relative TFP of the tradeable sector across countries, based on the relationship between trade and TFP in the model of Eaton and Kortum (2002). The logic of our approach is to measure TFP not from its "primitive" (the production function) but from...

This paper extends some theoretical results of Morris and Shin (1998) concerning the role of uncertainty about fundamentals in currency crises and tests their empirical relevance using a novel approach based on the distribution of survey expectations. Econometric evidence from the Asian crisis...
