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...

Trade policy commitments to lower import tariffs and to maintain tariffs at low levels entail short and long-run political-economic costs and benefits. Empirical work examining the relationship between such commitments and the exercise of trade policy flexibilities is still relatively nascent,...

For a representative sample of manufacturing firms in 26 countries, this paper shows that changes in the cost of importing over time are significantly and negatively correlated with changes in the percentage of firms' material inputs that are of foreign origin. Furthermore, the paper shows that...

Food prices in international markets spiked upward in 2008, doubling or more in a matter of months. Evidence is still being compiled on policy responses over the following two years, but lessons can be learned from the price spike in 1973, the magnitude and speed of which were similar to those...

The objective of this paper is to provide indicators of trade restrictiveness that include both measures of tariff and nontariff barriers for 91 developing and industrial countries. For each country, the authors estimate three trade restrictiveness indices. The first one summarizes the degree of...

This study examines recent effective rates of protection across the Egyptian economy, using an ad valorem price wedge introduced by nontariff barriers and energy subsidies, and compares today's effective rates of protection with those of a decade ago. The study uses 23 aggregated sectors from...

The authors create a standards restrictiveness index using newly available data on maximum residue levels of pesticides for 61 importing countries. The paper analyzes the impact that food safety standards have on international trade of agricultural products. The findings suggest that more...

The use of computable general equilibrium (CGE) simulation models for policy analysis has become widespread. However, such techniques are not well suited to economywide analysis in developing countries. Instead, simulation models relying on "borrowed" parameter estimates have been used for a...

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...
