How do global supply chain linkages modify countries' incentives to impose import protection? Are these linkages empirically important determinants of trade policy? To address these questions, this paper introduces supply chain linkages into a workhorse terms-of-trade model of trade policy with...

There is not yet consensus in the trade agreements literature as to whether preferential liberalization leads to more or less multilateral liberalization. However, research thus far has focused mostly on tariff measures of import protection. This paper develops more comprehensive measures of...

This paper surveys empirically the broad features of trade policy in goods for 31 major economies that collectively represented 83 percent of the world's population and 91 percent of the world's GDP in 2013. It addresses the following five questions: Do some countries have more liberal trading...

Suppose that when addressing the question of ?what?s left for the WTO?,? tariff negotiators relied not on the agenda established in 2001 but instead on the terms-of-trade theory of trade agreements to identify negotiating priorities. This paper uses the lens of the terms-of-trade theory to...

The WTO has delivered policy outcomes that are very different from those likely to emerge out of the recent wave of preferential trade agreements (PTAs). Should economists see this as an efficient institutional hand-off, where the WTO has carried trade liberalization as far as it can manage, and...

This paper examines the implications of the terms-of-trade theory for the determinants of outcomes arising under the enforcement provisions of international agreements. Like original trade agreement negotiations, the paper models formal trade dispute negotiations as potentially addressing the...

This paper introduces a new data set and establishes a set of basic facts and patterns regarding the trade that countries fight about under World Trade Organization (WTO) dispute settlement. The paper characterizes the scope of products, as well as the levels of and changes to the trade values,...

Two of the most important trade policy developments to take place since the 1980s are the expansion of preferential trade agreements and temporary trade barriers, such as antidumping, safeguards, and countervailing duties. Despite the empirical importance of preferential trade agreements and...

This paper surveys political-economic research on the variety of instruments that governments use to conduct international trade policy. It presents key insights on the relationships between instruments such as tariffs, quotas, voluntary export restraints, and other nontariff barriers, as well...
