Weak enforcement of international contracts can substantially reduce international trade. We develop a model where agents build reputations to overcome the difficulties that this institutional failure causes in a context of incomplete information. The model describes the interplay between...

Under a customs union, countries can exchange preferential market access by coordinating external tariffs to shift profits from excluded countries. I show that the exporting rents resulting from this coordination can offset trade diversion losses produced by the union, even if its members are...

Firms need to incur substantial sunk costs to break in foreign markets, yet many give up exporting shortly after their first experience, which typically involves very small sales. Conversely, other new exporters shoot up their foreign sales and expand to new destinations. We investigate a simple...

Special and Differential Treatment for Developing Countries (SDT) constitutes a central feature of the GATT/WTO system. Its formal goal is to foster export-led growth in developing countries. Its theoretical foundations and empirical support are, however, weak at best. In particular, SDT...

Countries worldwide have implemented lockdown measures to contain the covid-19 pandemic. After more than three months of restrictions to economic activities in many countries, the question has turned to the best ways to lift lockdowns while keeping the epidemic in check. Here I use basic...

We show that the Brazilian trade liberalization in the early 1990s led to a permanent relative decline in the vote share of left-wing presidential candidates in the regions more affected by the tariff cuts. This happened even though the shock, implemented by a right-wing party, induced a...

We study, theoretically and empirically, how countries choose intra-bloc tariffs and preferential margins when they form Preferential Trade Agreements (PTAs). Our model indicates that countries should set systematically lower preferential margins when the bloc takes the form of a free trade area...

We study the relationship between participation in free trade agreements (FTAs) and the sustainability of democracy. Our model shows that FTAs can critically reduce the incentive of authoritarian groups to seek power by destroying protectionist rents, thus making democracies last longer. This...
