We show that the entry of private profit-maximising firms makes the consumers worse off compared to having a nationalised monopoly. Such entry increases the nationalised firm’s profit, industry profit, and social welfare, at the expense of the consumers. Our result is important for competition...

This paper investigates the endogenous choice of the strategic variable, price or quantity, taken in a mixed duopoly by a public and a private firm prior to market competition. While Matsumura and Ogawa (2012) in a standard mixed duopoly find that price is the unique equilibrium, we show that,...

This note shows that the argument of Beladi and Chao (2006) [Beladi, H., Chao, C., 2006. Does privatization improve the environment? Economics Letters 93, 343–347] that privatization can harm the environment by inducing lower pollution tax is incorrect. It then modifies the model to restore...

We analyze a mixed oligopoly with free entry by private firms, assuming that a public firm maximizes an increasing function of output, subject to a break-even constraint. We establish an irrelevance result: whenever a mixed oligopoly is viable, then aggregate output, aggregate costs and welfare...

We analyse the relative welfare effects of an R&D and an output subsidy in a mixed duopoly. We show that an R&D subsidy is beneficial for society as a whole, and socially superior to an output subsidy, when spillovers are sufficiently high. Otherwise, an output subsidy is socially superior.

This paper analyzes the unilateral choices of application compatibility by platforms and the endogenous affiliations of two different groups (content providers and users). We find a novel result that for both platforms to unilaterally choose application compatibility is not an equilibrium unless...

This paper extends a discrete-choice model of differentiated product demand to consider consumer heterogeneity in dynamic games. Our approach applies to games involving both multi-product firms and static price competition.

This paper examines the effects of obtaining a strategic advantage of becoming the leader in the market on insiders’ incentives to merge and consumer welfare. We show that being the market leader is privately profitable for the merging insiders. We also show that the leading merger would...

This paper investigates the impacts of competition structures on firms’ incentives for adopting strategic environmental corporate social responsibility (ECSR) certified by a Non-Governmental Organization. We show that, to induce firms to adopt certified ECSR, the certifier will set a standard...

This paper examines the welfare implication of banning price discrimination in the intermediate goods market in which a monopolistic supplier contracts with asymmetric downstream retailers. We demonstrate that the supplier has a strong incentive to manipulate the interdependent demand structure...
