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 assesses the impact of the North American Free Trade Agreement on Mexican manufacturing plants’ prices and markups. We distinguish between Mexican goods that are exported and those sold domestically, and decompose their prices separately into markups and marginal costs. We then...

We study how NAFTA changed the geography of violence in Mexico. We propose that this open border policy increased trafficking profits of Mexican cartels, resulting in violent competition among them. We test this hypothesis by comparing changes in drug-related homicides after NAFTA’s...

The Conference of the Parties (COP) has proven a valuable outlet to advance the climate agenda. The combination of high media coverage, extremely high expectations set by influential environmentalists, and unanimity rules has, however, started to limit its effectiveness. Technical issues can...

We study the role of firms in the political economy of trade agreements. Using detailed information from lobbying reports filed under the Lobbying Disclosure Act, we find that virtually all firms that lobby on free trade agreements (FTAs) support their ratification. Moreover, relative to...

We challenge the common practice of estimating gravity equations with time-interval data in order to capture dynamic-adjustment effects to trade-policy changes. Instead, we point to a series of advantages of using consecutive-year data recognizing dynamic-adjustment effects. Our analysis reveals...

How do firms of different sizes react to trade liberalization? Leading theories suggest that, amongst continuing exporters, lower trade costs should boost exports of smaller firms by the same or a greater rate than those of larger firms. However, studying the entry into force of the ambitious...

We use a unique case study to estimate the effect of withdrawing from a free trade agreement on international trade. Lately, the political opposition to international economic cooperation has been on the rise, but little is known about how the withdrawal from a trade agreement affects trade. We...

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...

Model uncertainty is inherent in the design of optimal environmental policy. We investigate the consequences in a simple linear model, where the aim of the policymaker is to stabilize the carbon content of the atmosphere. We study how decision-makers' concerns about robustness alter policy using...
