We consider a bilateral monopoly with a supplier and a buyer. Their trading terms are determined through negotiations, but affected by the buyer's efforts to search for outside suppliers. We find surprisingly that a market expansion may harm the supplier.

This study constructs a model of anticompetitive exclusive contracts in the presence of complementary inputs. A downstream firm transforms multiple complementary inputs into final products. When complementary input suppliers have market power, upstream competition within a given input market...

This study constructs a model of anticompetitive exclusive-offer competition between two existing upstream firms. Under exclusive-offer competition, the upstream firm's profit depends on the rival's exclusive offer. If the rival makes an exclusive offer acceptable for the downstream firm, the...
