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 studies a simple, tractable model of labor adjustment in a trade model that allows researchers to analyze the economy's dynamic response to trade liberalization. Since it is a neoclassical market-clearing model, duality techniques can be employed to study the equilibrium and, despite...

This paper analyzes Zambian export patterns using a new transaction-level trade data set for the period 1999-2011. The data show that, in international comparison, Zambian exports are exceptionally concentrated (on mining products). This reliance has been increasing in recent years. Zambia's...

This paper examines the effects of robotization on trade patterns, wages and welfare. It develops a Ricardian model with two-stage production and trade in intermediate and final goods in which robots can take over some tasks previously performed by humans in a subset of industries. An increase...

The Middle East and North Africa (MENA) region's trade performance over the past two decades has been disappointing. Efforts to boost trade through a plethora of regional trade agreements (RTAs) are underway. This study examines the potential contribution of regional trade agreements, as well as...

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...

Would improvements in port performance increase trade in countries on the Indian and Western Pacific Oceans? Previous studies attempted to answer this question using ad hoc measures of port efficiency that do not control for the actual use of port assets or measures that can be very noisy. To...

This paper studies the effects of trade policy uncertainty on the extensive and intensive margins of trade for a sample of 65 exporters at the Harmonized System six-digit level. The paper measures trade policy uncertainty as the gap between binding tariff commitments under trade agreements...

This paper characterizes the trade-off between the income gains and the inequality costs of trade using survey data for 54 developing countries. Tariff data on agricultural and manufacturing goods are combined with household survey data on detailed income and expenditure patterns to estimate the...
