We investigate the possibility of using public firms to regulate polluting emissions in a Cournot oligopoly where production takes place at constant returns to scale and entails a negative environmental externality. We model the problem as a differential game and investigate (i) the Cournot-Nash...

This paper discusses an oligopoly where firms exert negative externalities upon each other. A theoretical model is developed for a market where these externalities are particularly relevant: the intra-day credit market, which is crucial for the operation of an efficient payments system. A...

Africa: A continent is waking up. Not through aid or wealth from the exploitation of natural resources, but through a technological revolution. The access to affordable mobile telecommunication. Inspired by deregulation and pioneered by local champions who have taken a lead in what is today's...

This paper studies the transition from monopoly by a public firm to mixed duopoly, in which public firm and private firm have heterogeneous objective functions. With different constant marginal costs, my theoretical model shows that the market prices and outputs do not change after entry by the...

A city establishes a garbage collection company in order to generate revenue, but destroys the business of an existing private garbage collection company in the process by supplanting the private company's customer base. As a general proposition, the private company has no right to complain...

I study the endogenous choice of a price or quantity contract in a mixed duopoly with a socially concerned firm which maximizes a combination of profit and consumer welfare. Contrasting the literature, I find that equilibria where firms adopt price contracts and quantity contracts might coexist....

We investigate the possibility of using public firms to regulate polluting emissions in a Cournot oligopoly where production generates pollution and public firms are less efficient than private ones. In a differential game we compare (i) the Markov-Perfect Nash equilibrium under social planning;...

In this paper we extend the results of Kreps and Scheinkman (1983) to mixedduopolies. We show that quantity precommitment and Bertrand competition yield Cournot outcomes not only in the case of private firms but also when a public firm is involved.
