This article investigates the effect of macroeconomic variable fluctuations on antidumping (AD) filing. Using a selected group of "new" users, we measure the relationship between macroeconomic variables and AD filing during 1994-2002 using a nominal binomial regression. Our results for exchange rate and domestic gross domes tic product (GDP) are similar, though more pronounced, to the results found in other studies on antidumping filing. However, unlike other papers we find a direct relationship between foreign GDP fluctuations and anti-dumping filing and, more importantly, the relationship for our selected countries is counter-intuitive. We provide some analysis for this anomaly.
