This paper analyzes market diffusion in the presence of oligopolistic interaction among firms. Market demand is positively related to past market size because of consumer learning, networks, and bandwagon effects. Firms enter the market freely in each period with fixed costs and compete in...

In this paper, we construct an interregional trade model that has en- dogenous fertility rates in the manner of Helpman and Krugman (1985). The presented model shows that fertility rates in a large region become lower than those in a small region because of the agglomeration of man- ufacturing...

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 paper constructs a model of anticompetitive exclusive dealings with potential downstream competition. Unlike in previous studies, the incumbent can establish a direct retailer with some fixed payment and can offer an exclusive contract to a downstream buyer twice. We show that the existence...

This study constructs a model for examining anticompetitive exclusive supply contracts that prevent an upstream supplier from selling input to a new downstream firm. With regard to the technology to transform the input produced by the supplier, as an entrant becomes increasingly efficient, its...

This study considers a Cournot duopoly market in which a clean firm can transfer its less polluting technology to a dirty firm through a fixed-fee licensing contract. We analyze the impacts of emissions taxes on the incentives of firms to transfer technology as well as on the total pollution...
