While models of mixed oligopoly have been analyzed within a rapidly growing literature, little is known about the mechanism of efficiency improvement relating to partial privatization. In this paper, we endogenize efficiency improvement in relation to the level of privatization. We show that in...

The aim of this paper is to investigate the welfare effect of privatization in oligopoly when the government takes into account the distortionary effect of raising funds by taxation (shadow cost of public funds). We analyze the impact of the change in ownership not only on the objective function...

We develop a model of endogenous network formation in order to examine the incentives for R&D collaboration in a mixed oligopoly. Our analysis reveals that the complete network, where each firm collaborates with all others, is uniquely stable, industry-profit maximizing and efficient. This...

We allow a general (non-uniform) consumer distribution in a mixed duopoly Hotelling model. We characterize respective conditions under which socially optimal pricing location are achieved. We find that, while the condition for socially optimal pricing is fairly general, that for a socially...

This paper analyzes the interaction between two political economy decisions by a government: whether to privatize a public firm and what environmental policy to choose (an environmental tax or an emission standard). We find that when market competition is weak the government does not privatize...

Several studies on mixed oligopoly indicate that the ownership pattern of firms does not affect the equilibrium price. This idea often suggests that ownership is irrelevant. In a mixed duopoly under price competition, firm ownership is irrelevant. This study reveals that ownership is irrelevant...

We develop a model of a mixed oligopoly to examine the role of R&D subsidies and evaluate the welfare effects of privatization. In solving the (n 1)-firms oligopoly model we make use of aggregative games techniques. Our analysis reveals that privatization reduces the optimal R&D subsidy, but...

We analyze a mixed duopoly where the government runs the public firm partly with the objective of maximizing the profits of the private firm. The incumbent does so to secure funding for its political party. We find that it results in lower (higher) overall output goods are substitutes...

This paper analyzes the interaction between two political economy decisions by a government: whether to privatize a public firm and what environmental policy to choose (an environmental tax or an emission standard). We find that when market competition is weak the government does not privatize...

Within a simple model of differentiated oligopoly, we show that tacit collusion may be prevented by the threat of nationalising a private firm coupled with the appropriate choice of the weight given to private profits in the maximand of the nationalised company. We characterise the properties of...
