Three years ago, very few economists would have imagined that one of the newest and fastest growing research areas in international trade is the use of quantitative trade models to estimate the economic welfare losses from dissolutions of major countries' economic integration agreements (EIAs)....

This paper reviews the most significant recent developments in the theory of trade agreements. The paper offers an integrated approach to evaluating trade agreements, and uses the approach to present results on preferential and multilateral trade agreements. The paper identifies also several...

This paper assesses for the first time the effect of regional trade openness on agglomeration within regions, using regional data on the trade of Colombia. The results of the panel model show that the effect of trade is sufficiently strong to shape the spatial configuration, a structure that...

We nest an extended two-way fixed effect (ETWFE) estimator for staggered difference-in-differences within the structural gravity model. To test the ETWFE, we estimate the effects of regional trade agreements (RTAs). The results suggest that RTA estimates in the current gravity literature may be...

We study the implications of trade aggregation in an infinite-horizon economy with multiple countries. Specifically, we ask whether there is a role for alternatives to the Armington aggregator in the workhorse open-economy macroeconomics model. We show analytically that the first-order dynamics...

This paper proposes a model of international trade with capital accumulation and financial intermediation. This is achieved by embedding the Melitz (2003) model into an incomplete-markets neoclassical framework with an endogenous credit market. The model preserves the analytical tractability of...
