This study constructs a simplest model to examine anticompetitive exclusive contracts that prevent a downstream buyer from buying input from a new up-stream supplier. Incorporating Nash bargaining into the standard one-buyer-one-supplier framework in the Chicago School critique, we show a...

Although outsourcing input production has long been considered as an important approach to help downstream manufacturers enhance structural efficiency, we provide a theoretical explanation for why outsourcing may negatively affect downstream firms' profitability. We consider a duopoly model...

We consider a downstream oligopoly model with one dominant and several fringe retailers, who purchase a manufacturing product from a monopoly supplier. We then examine how the supplier's outside option influences the relation between the dominant retailer's bargaining power and the equilibrium...

We examine a game of competition with access provision in which service quality is endogenously determined through infrastructure upgrades with spillovers. There are two types of equilibria in the free competition regime. In particular, voluntary access provision with an access charge higher...

We extend the well-known spatial competition model (d'Aspremont et al., 1979) to a continuous time model in which two firms compete in each instance. Our focus is on the entry timing decisions of firms and their optimal locations. We demonstrate that the leader has an incentive to locate closer...

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...
