Traditional weighted-average measures of trade distortions are widely used in analyzing global and regional reforms, despite well-known deficiencies. This paper develops and applies optimal aggregators for the real-world case of multiple countries and commodities with much more detailed...

This paper analyzes the impacts of selected trade facilitation measures on international trade flows. A gravity model is used to estimate four equations: a pooled cross-section model; a fixed-effects model; a random effects model; and a Poisson maximum likelihood estimator. The contribution of...

This paper examines the relationship between openness and within-country regional inequality across 28 countries over the period 1975-2005, paying special attention to whether increases in global trade affect the developed and developing world differently. Using a combination of static and...

The spread of global value chains (GVCs) has given rise to new statistical tools, the Inter-Country Input-Output tables and new analytical frameworks aimed at properly identifying production linkages between and within economies. However, several important questions remain unaddressed. This...

This paper provides up-to-date characterization of the association between trade and GDP comovement -- also called the trade comovement slope -- for 150 countries from 1962 to 2011. The paper shows that trade is significantly linked to more GDP correlation, either directly through bilateral...

Services play a role in global value chains in many ways, similar to goods. But services deserve special attention because of how they are transacted, how they affect downstream sectors, how they are regulated, and how international cooperation can contribute to integrating national markets....

Preferential trade agreements have become deeper over time, often encompassing policy areas that go beyond traditional trade policy, such as investment, competition, and intellectual property rights protection. In the literature, a prominent argument why countries sign "deep" agreements is to...

This paper uses data on directional trade flows and Regional Trade Agreements (RTA) to i) estimate the effects of RTA on trade flows and ii) assess the importance of Global Value Chains for these effects. Based on a Difference-in-Difference identification strategy, we find that RTAs are...

Is the variation in bilateral trade flows across countries primarily due to differences in the number of exporting firms (the extensive margin) or in the average size of an exporter (the intensive margin)? And how does this affect the estimation and quantitative implications of the Melitz (2003)...

Using an empirical model, this study provides some insights into the functioning of the oilseed-biodiesel-diesel market complex in a large country that determines the biodiesel price, reflecting market equilibrium changes resulting from volatility in the crude oil price. Oilseed crushing...
