Antidumping tariff : the case of certain frozen fish fillets from Vietnam.

In 2003, certain catfish fillets from Vietnam were claimed as having been dumped into the United States market, causing material injuries to domestic producers, and were assessed antidumping duties in the range of 37 to 64 percent. This study analyzes the effect of antidumping duties on imports of catfish from Vietnam in terms of volume, value and price at country and firm level. Data is compiled from the Vietnam Association of Seafood Exporters and Producers, the United States Department of Agriculture, and the United States International Trade Commission. Difference-in-Difference estimation is employed and made robust to different group/time variances. The result of estimation is statistically significant in largely decreasing prices of Vietnamese catfish and volume/value of exports at firm level, but not statistically significant at country level.
