Built on the location model, this paper studies the rivalry of two firms in an industry through two-part tariffs. It is found that kinky profit functions are responsible for the coincidence of imperfectly competitive equilibrium and cartelization outcome. A duopoly likely results in higher entry...

We discuss network neutrality regulation of the Internet in the context of a two-sided market model. Platforms sell broadband Internet access services to residential consumers and may set fees to content and application providers on the Internet. When access is monopolized, cross-group...

Investments in Generating Capacities between a monopolist and two competing firms are compared where the firms invest in their capacity and fix the retail price while electricity demand is uncertain. A unit price auction determines the wholesale electricity price when the firms compete. They...

We discuss the benefits of net neutrality regulation in the context of a two-sided market model in which platforms sell Internet access services to consumers and may set fees to content and applications providers on the other side of the Internet. When access is monopolized, we find that...

The so-called excess-entry theorem (Mankiw and Whinston 1986, Suzumura and Kiyono, 1987) establishes conditions guaranteeing that more firms enter a homogeneous Cournotoligopoly in equilibrium than a benevolent government prefers. We generalise the approach and analyse the behaviour of a...

To study the coexistence of two different ownership forms within anindustry, I develop a simple model of competition between one for-profit and one nonprofit firm. The two firms have different objectives and face different constraints due to their choice of ownership status. Assuming...
