Small fish–big issues: the effect of trade policy on the global shrimp market

It is a well-established theoretical result that the trade policy of a large country can directly affect its own and other countries' welfares by affecting international goods' prices. However, there exist very few empirical studies that analyze the effect of trade policy on international prices. With detailed data on unit values and tariffs, I show how policy actions in Europe disrupted the global shrimp market in a non-negligible way and set the stage for the anti-dumping case in the United States. The loss of Thailand's preferential trade status in Europe and the international differences in food-safety standards during the antibiotics crisis shifted especially Thai, Vietnamese, and Chinese shrimp exports away from Europe toward the United States in the late 1990s and early 2000s. I document how those shifting markets have decreased US prices for shrimp significantly compared to those in Europe.
