The Spread of Antidumping Regimes and the Role of Retaliation in Filings

Over the past decade, the worldwide use of antidumping has become very widespread—41 WTO‐member countries initiated antidumping cases over the 1995‐2003 period. From another perspective, U.S. exporters were subjected to 139 antidumping cases during this period, by enforcement agencies representing 20 countries. In this context, it is natural to consider whether antidumping filings may be motivated as retaliation against similar measures imposed on a country's exporters. This is the focus of our study, though we also control for the bilateral export flows involved and nonretaliatory impacts of past cases, with other motivations—macroeconomic, industry‐specific, and political considerations—dealt with through fixed effects. Applying probit analysis to a WTO database on reported filings, we find strong evidence that retaliation was a significant motive in explaining the rise of antidumping filings over the past decade, though interesting differences emerge in the reactions to traditional and new users of antidumping.
