The recent developments in information technology (IT) have enabled firms to employ personalized pricing. Should all firms employ personalized pricing even though the adaptation costs of such pricing strategies are not high? This paper theoretically demonstrates a situation in which all firms do...

This paper formulates a duopoly model of firms concerned with relative profits as well as their own profits and investigates the relationship between the degree of competitiveness in a market and R&D expenditure. We find a non-monotone relationship between the two variables. When the duopoly...

We investigate a mixed duopoly, where a state-owned welfare-maximizing public firm competes against a profit-maximizing private firm. We use a Hotelling-type spatial model which represents product differentiation. We endogenize production costs by introducing cost-reducing activities. We show...

Using a standard linear city model with two firms, we consider how their licensing activities following their R&D investments affect the locations of the firms and the effort levels of the R&D investments. Although recent studies show that R&D investments that may cause a large cost differential...

We investigate a mixed market in which a state-owned, welfare-maximizing public firm competes against profit-maximizing n domestic private firms and m foreign private firms. A circular city model with quantity-setting competition is employed. We find that the equilibrium location pattern depends...

We investigate the manner in which vertical separation affects lobbying activities as well as the access charges for essential facilities. We find that vertical separation either increases or decreases the access charge, and this depends on the relative efficiency between the incumbent and new...
