In 2003, after claims of dumping, the United States imposed heavy tariffs on Vietnamese catfish, which led to a collapse of imports. We use panel data to explore household responses in the catfish-producing Mekong delta between 2002 and 2004 and find that income growth was significantly slower among households relatively more involved in catfish farming in 2002. This is explained by a relative decline in both catfish income and revenues from other miscellaneous farm activities. Labor supply did not adjust, most likely because of off-farm employment limitations. Households more exposed to the shock reduced the share of investment assigned to catfish while substituting into agriculture.

This paper explores the links between exports, export destinations, and skill utilization. We identify two mechanisms behind these links: differences across destinations in quality valuation and in exporting required services, activities that are intensive in skilled labor. Depending on the characteristics of the source country (income, language), the theories suggest a skill-bias in export destinations. We test the theory using a panel of Argentine manufacturing firms. We find that Argentine firms exporting to high-income countries hired more skilled workers than other exporters and domestic firms. Instead, we cannot identify any causal effect of exporting per se on skill utilization. (JEL F14, F16, J24, L60, O14, O19)
