We show that multilateral tariff binding liberalization substantially impacts the nature and extent of Preferential Trade Agreement (PTA) formation. First, it shapes the nature of forces constraining expansion of Free Trade Agreements (FTAs). The constraining force is a free riding incentive of...

We study how domestic content requirements in Free Trade Areas (FTAs) affect market power and market structure in concentrated intermediate goods markets. We show that content requirements increase oligopolistic markups beyond the level that would obtain under an equivalent import tariff, and we...

Geography, economic size, or common history, help predicting signed regional trade agreements (RTAs). However, not all signed RTAs are "natural" according to economic determinants. En-dogeneity and general equilibrium effects of RTAS are the two mechanisms addressed in this paper. We estimate...

Regional trade agreements have proliferated in the past two decades while multilateral trade negotiations have stalled. Both these agreements are governed by the WTO and have to abide by the non-discriminatory (Most-Favored Nation, MFN) clause to varying degrees-regional agreements to a lesser...

This paper argues that the large reduction in corporate tax rates and only gradual widening of tax bases in many countries over the last decades are consistent with tougher international competition for foreign direct investment (FDI). To make this point we develop a model in which governments...

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, 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 number of preferential trade agreements has greatly increased over the past two decades, yet most existing bilateral arrangements take the form of free trade areas, and less than ten percent can be considered to be fully fledged customs unions. This paper develops a political economy model...
