In this paper I quantify the welfare gains of the 2004 EU enlargement as a result of the abolition of border controls, both for incumbents and for new members. I build a multi-sector Ricardian model, allowing for linkages across sectors, similar to the one in Caliendro and Parro (2011). As with...

This paper studies the non-parametric identification of the discount factor and utility function in the class of dynamic discrete-continuous choice (DDCC) models. In contrast to the discrete-only model we show the discount factor is identified. Our results further highlight why Euler equation...

An intertemporal general equilibrium model of the United States and MERCOSUR is created to analyze the dynamic adjustments in both regions' commodity and capital markets after trade liberalization. Simulation results show that tariff reductions initiated by MERCOSUR have small positive effects...

This paper shows that bilateral currency crises reduce bilateral trade up to 50% after controlling for the depreciation rate. Using a trade model, these reductions are connected to the welfare costs of currency crises. The results show that a single currency crisis can result in welfare...

Using varieties of a rich model that considers sectoral heterogeneity and input-output linkages, this paper shows that the overall welfare gains of a region within a country can be decomposed into domestic versus international welfare gains from trade. Empirical results based on state-level data...

Using daily price and quantity data on imported and domestic agricultural products, this paper estimates the elasticity of substitution between home and foreign goods (i.e., the Armington elasticity), the elasticity of substitution across goods, and the elasticity of substitution across...

With non-homothetic preferences, a monopolistic competition equilibrium is inefficient in the way inputs are allocated towards production. This paper quantifies a gains from trade component that is present only when reallocation is properly measured in a setting with heterogeneous firms that...

We discuss how the welfare ranking of fixed and flexible exchange rate regimes in a New Open Economy Macroeconomics model depends on the interplay between the degree of exchange rate pass-through and the elasticity of substitution between home and foreign goods. We identify combinations of these...
