This paper proposes an n-firm homogeneous-good Bertrand model with private information about costs. The model allows …

A finite number of sellers (n) compete in schedules to supply an elastic demand. The costs of the sellers have … with more noise in the private signals or more correlation among the costs parameters. In fact, for large values of noise …

Recovery of stranded costs is perhaps the most litigious issue encountering regulators in promoting competition in … particular regulatory mechanism regularly employed in United States and also in Spain for settling stranded costs payments, the … competition and stranded costs recovery are not necessarily incompatible. Mechanism design is the key element in welfare analysis …

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 …

In a framework with an upstream monopoly and a downstream duopoly, we analyze the impact of convex costs on the … downstream level. In contrast to the case of constant marginal costs, vertical integration does not imply complete market …
