This paper estimates the impact of antidumping protection on export behavior of French firms covered by antidumping cases. Traditional models suggest that all domestic firms covered by antidumping protection should benefit from
protection. However, in an environment of globally fragmented supply chains, firms may be damaged by protection if duties increase input costs for firms covered by the protection. Results from this paper indicate that while non-exporting firms benefit from protection, domestic sales of export-oriented firms and exports in general, are
depressed due to protection. This effect is more severe for multinational firms.
