We model demand for quality differentiated goods to derive a relationship between trade costs and the quality composition of trade. Detailed data on traded goods' prices, quantities and shipping costs for many importers and exporters are used to test these predictions. These data provide a...

This is the first paper to provide a theoretical model that connects the quality of product-level bilateral trade flows with the geographic position of the exporter. We show that, in addition to commonly used importer characteristics, quality increases (i) in trade-weighted specific...

Developing countries pay substantially higher transportation costs than developed nations, which leads to less trade and perhaps lower incomes. This paper investigates price discrimination in the shipping industry and the role it plays in determining transportation costs. In the presence of...

Cocaine trafficking has a significant but understudied influence on Central American economies. The economic implications of this trade have repercussions for both regional development and drug control policy debates, and therefore deserve greater attention. Towards that end, in this paper we...

The authors argue that endogeneity of transportation costs needs to be taken into account when estimating the effect of distance on trade. Otherwise, the estimates of the distance effect may be biased and inconsistent. Endogenous transportation can introduce slope heterogeneity and spatial...
