The United Kingdom has opted to leave the European Union. The trade and welfare consequences of this decision are large; most studies predict a trade and welfare loss for both the UK and the EU. The UK parliament has indicated that it aims for new and ambitious trade agreements following Brexit,...

We use an empirical gravity equation approach to study how nonreciprocal trade preferences (NRTPs), enacted mainly through the Generalized System of Preferences, affect the exports of the beneficiary nations. In line with existing studies, the average trade effect stemming from nonreciprocal...

We study how a preferential trade agreement (PTA) affects international sourcing decisions, aggregate productivity and welfare under incomplete contracting and endogenous matching. Contract incompleteness implies underinvestment. That inefficiency is mitigated by a PTA, because the agreement...

In explaining the uneven spatial distribution of economic activity, urban economics and new economic geography (NEG) dominate recent research in economics. A main difference between these two approaches is that NEG stresses the role of spatial linkages whereas urban economics does not do so. We...

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...

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...

The withdrawal of the United Kingdom from the European Union has had disruptive effects on international trade. As part of its 'Global Britain' strategy, in the wake of Brexit, the UK is pursuing a series of Free Trade Agreements with countries around the world, including Canada, Japan, Korea,...

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 the welfare impact of rules of origin in free trade agreements where final-good producers source customized inputs from suppliers within the trading bloc. We employ a property-rights framework that features hold-up problems in suppliers' decisions to invest, and where underinvestment is...

In a seminal paper, Rose (2004) found that the assumed positive impact of the WTO on international trade was questionable. This finding has been scrutinized and modified in subsequent research, using different datasets, econometric methods and separating the WTO from other forms of trade...
