This paper analyzes the market diffusion of a new product whose quality is uncertain. Consumers learn the product quality by observing the history of market outcomes. Firms cannot observe how consumers evaluate the product quality and learn it in response to consumerfs behavior. As a result of...

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 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...

When we speak of Japanese overseas expansion, we are concerned with the expansion of Japanese businesses into Asia and with the emigration of the Japanese into this region for economic reasons. But any discussion of this subject must go beyond merely examining problems of business or uhomo...

This paper analyses market capacity expansion in the presence of inter-temporal consumption externalities such as consumer learning, networks and bandwagon effects. An externality leads to an endogenous shift of market demand that responds to past market capacity. Whereas market capacity grows...

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...

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 dealing in the presence of multiple entrants. Unlike the single-entrant model in previous literature, an entrant competes not only with the incumbent to deal with buyers but also with other entrants. The competition among entrants then...
