Gravity equations have been used for more than 50 years to estimate ex post the partial effects of trade costs on international trade flows, and the well-known -- and traditionally presumed exogenous -- “trade-cost elasticity” plays a central role in computing general equilibrium trade-flow...

We build a model of tacit collusion between firms that operate in multiple markets to study the effects of trade costs. A key feature of the model is that cartel discipline is endogenous. Thus, markets that appear segmented are strategically linked via the incentive compatibility constraint....

When two countries conclude a free trade agreement (FTA), they define rules of origin (RoOs) to determine whether a product is eligible for preferential treatment. RoOs exist to avoid that exports from third countries enter the FTA through the member with the lowest tariff (trade deflection)....

This paper reviews the most significant recent developments in the theory of trade agreements. The paper offers an integrated approach to evaluating trade agreements, and uses the approach to present results on preferential and multilateral trade agreements. The paper identifies also several...

If a free trade agreement (FTA) is characterized by the exchange of market access with a large and competitive trading partner, the agreement can cause a leakage of protectionist benefits to domestic industry from lobbying against external tariff cuts. This rent destruction effect of an FTA can...

Bilateral investment treaties (BITs) have proliferated over the past 50 years such that the number of pairs of countries with BITs is roughly as large as the number of country-pairs that belong to bilateral or regional preferential trade agreements (PTAs). The purpose of this study is to provide...

What has been the overall global welfare impact of the accession to the World Trade Organization of a large country like China, or the global welfare impact of the completion of the Uruguay round of GATT negotiations? Can we come up with a simple user-friendly formula to calculate the global...

Natural resources account for 20% of world trade, and dominate the exports of many countries. Policy is used to manipulate both international and domestic prices of resources, yet this policy is largely outside the disciplines of the WTO. The instruments used include export taxes, price...

We examine the gains from Chinese accession to the WTO. Using Arkolakis, Costinot, and Rodríguez-Clare (2012) we provide a new quantitative welfare measure by dividing the manufacturing sector into import and export sub-sectors. We then evaluate how the increased openness caused by China's...
