Market share, cost-based dumping, and anti-dumping policy

This paper studies the occurrence of dumping and the implications of anti-dumping duties in a deterministic price-setting two-period duopoly model for differentiated products. When current market shares matter for future demand, cost-based dumping can be profitable. Dumping thus arises as a form of investment in market shares. This might trigger the application of anti-dumping law. We further show that correctly anticipated duties do not necessarily hinder firms from selling below costs. The mere existence of anti-dumping law, however, significantly changes the structure of the game, leading to higher first-period prices for both firms. JEL Classification: F12, F13.
