This paper investigates the effects of U.S. AD actions on DCs. It first considers administrative actions by the U.S. Department of Commerce, which decides AD margins for countries. It then considers decision making by the U.S. International Trade Commission, which determines injury to domestic industry. The econometric results show that USDOC actions lead to significantly higher AD margins for NMEs (all DCs) than for MOEs. Among countries that suffer from U.S. AD actions DCs have a significantly higher ratio of dumped imports to total imports (relative dumped imports) compared with middle income countries. However, the results also show that relative dumped imports of high income countries are also greater than middle income countries.
