Abstract
The competitive effect of international market integration in industries with imperfect com-
petition is of great policy interest. This paper focuses on the link between monopolization and
market segmentation. It presents a model of multi-market entry deterrence with or without
market commitments. We derive sufficient conditions for entry deterrence with productive ca-
pacity in the multi-market game. It is shown that to deter entry in the multi-market game, the
first-mover installs productions capacity which is strictly larger than the capacity needed to de-
ter entry, if it is possible to assign parts of the capacity to specific markets. Market integration
for production capacity may, thus, have a pro-competitive effect in international markets.
