This paper introduces the Exporter Dynamics Database. The database includes exporter characteristics and measures of exporter growth based on firm-level customs information from 38 developing and seven developed countries, primarily for the period between 2003 and 2010. The measures are...

This paper shows that the top 1 percent of exporters critically shape trade patterns, using firm-level data from 32 countries. In particular, variation in average firm size (the intensive margin) explains over two thirds of the variation in the sector distribution of exports across countries,...

This paper uses highly disaggregated trade data to investigate geographic and product diversification patterns across a group of developing nations for the period from 1990 to 2005. The econometric investigation shows that the gravity equation fits the observed differences in diversification...

The volume of world trade has grown more than twice as fast as real world income since 1980. Surprisingly, the effect of distance on trade has increased during this period. It could be that countries are trading greater volumes of goods that are highly sensitive to distance. An alternative...

The authors determine how time delays affect international trade using newly collected World Bank data on the days it takes to move standard cargo from the factory gate to the ship in 126 countries. They estimate a modified gravity equation, controlling for endogeneity and remoteness. On...

This paper examines the effect of regionalism on unilateral trade liberalization using industry-level data on applied most-favored nation tariffs and bilateral preferences for ten Latin American countries from 1990 to 2001. The findings show that preferential tariff reduction in a given sector...

This paper examines the effects of transit, documentation, and ports and customs delays on Africa’s exports. The authors find that transit delays have the most economically and statically significant effect on exports. A one-day reduction in inland travel times leads to a 7 percent increase in...

The author examines the impact of historical global downturns on trade flows. The results provide insight into why trade has dropped so dramatically in the current crisis, what is likely to happen in the coming years, how global imbalances are affected, and which regions and industries suffer...

The authors study the effects of trade barriers and the persistence of past linkages on trade flows in the former Soviet Union. Estimating a gravity equation on trade among and between nine Russian regions and 14 former Soviet republics, they find that Russian regions traded 60 percent more with...

The author uses detailed trade, tariff, and income data for countries involved in 91 trade agreements negotiated since 1980 to test for reciprocity in free trade agreements. The results offer strong evidence of reciprocity in North-North and South-South free trade agreements, but there is little...
