Estimating the Impact of Anti-dumping and Anti-cartel Actions Using Intervention Analysis.

Intervention analysis is proposed as a method for estimating the effects of antidumping actions in the presence of a domestic cartel. Data requirements and modeling effort compare favorably with traditional structural model approaches. The method is applied to an antidumping action brought to the European Commission and in which the European producers of the product were fined after an anticartel action by the Commission covering an overlapping period. Intervention analysis is applied to distinguish the effects of the antidumping action from those of changes in cartel behavior.
