Median voter theory applied to trade policy predicts positive tariffs in capital-abundant countries and negative tariffs in labor-abundant countries. Negative tariffs are rare, and this paper reconciles the median voter theory with observed protectionism across countries. By considering large...

The theoretical result that there are welfare gains from trade is a central tenet of international economics. In a class of trade models that satisfy a "gravity equation," the welfare gains from trade can be computed using only the open economy domestic trade share and the elasticity of trade...

This paper derives a micro-founded gravity equation in general equilibrium based on a translog demand system that allows for endogenous markups and substitution patterns across goods. In contrast to standard CES-based gravity equations, trade is more sensitive to trade costs if the exporting...

Although economists have long been aware of Jensen's inequality, many econometric applications have neglected an important implication of it: the standard practice of interpreting the parameters of log-linearized models estimated by ordinary least squares as elasticities can be highly misleading...

The paper explores the determinants of industry location across interwar Poland. After more than 120 years ofpolitical and economic separation, Poland was reunified at the end of 1918. In consequence, its industry facedmassive structural changes: the removal of internal tariff barriers and...

This paper shows that the WTO's Article XXIV increases the likelihood of free trade, but may worsen world welfare when free trade is not reached and customs unions (CUs) form. We consider a model of many countries. Article XXIV prevents a CU from raising its common external tariff, which makes...

Labor market consequences are at the forefront of most debates on the merits of trade liberalization. Preferential trade agreements (PTAs) have become the primary form of trade liberalization in most countries, and several studies have shown that discriminatory and nondiscriminatory trade...

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...

This paper reviews the theoretical and the empirical literature on regionalism. The formation of regional trade agreements has been, by far, the most popular form of reciprocal trade liberalization in the last fifteen years. The discriminatory character of these agreements has raised three main...

We examine the qualitative and quantitative predictions of a heterogeneous firm model à la Melitz (2003) in the context of the Canada - US Free Trade Agreement (CUSFTA) of 1989. We calibrate our model to the pre-trade liberalization stage, simulate the trade liberalization, and compute the...
