We ask under what conditions transmission contracts increase or mitigate market power. We show that the allocation process of transmission rights is crucial. In an efficiently arbitraged uniform price auction generators will only obtain contracts that mitigate their market power. However, if...

Eine formale Analyse der Firmen- und Branchenentwicklung muß nicht auf so stark vereinfachenden und damit unrealistischen Annahmen zurückgreifen, wie dies in neoklassischen Modellen geschieht. Evolutorische Simulationsmodelle bieten sich hier als eine Alternative an. Sie gestatten eine...

Quite often, a firm has to decide between investing in a safe project (``small'') where rewards and losses remain moderate and a risky alternative (``big'') where the rewards and the losses are larger. We study such a choice in a context where the probability of success depends both on the...

This paper evaluates the effectiveness of several pricing rules intended to promote entry into a network industry dominated by an incumbent carrier. Drawing on the work of Cournot and Hotelling, we develop a model of competition between two interconnected networks. In a symmetric equilibrium,...

We discuss the effects of strategic commitments and of network size in the process of setting interconnection fees across competing networks. We also discuss the importance of the principles of reciprocity and imputation of interconnection charges on market equilibria. Reciprocity means that...

This study reports experimental market power and efficiency outcomes for a computational wholesale electricity market operating in the short run under systematically varied concentration and capacity conditions. The pricing of electricity is determined by means of a clearinghouse double auction...

The health care industry is being transformed. Large firms are merging and acquiring other firms. Alliances and contractual relations between players in this market are shifting rapidly. Within the next few years, many markets are predicted to be dominated by a few large firms. Antitrust...

The paper sheds light on two questions, using transaction cost theory: 1) Why do management consultants exist, and 2) why do they organize in independent firms. The paper also contains a history of the management consulting industry.

Este trabajo analiza la entrada y la competencia en servicios de telecomunicaciones, en los que las empresas se diferencian por sus costes hundidos y por la valoración que reciben de los consumidores. En este marco de análisis desaparece el problema de coordinación presente en la literatura...

We consider innovation incentives in markets where final goods comprise two strictly complementary components, one of which is monopolized. We focus on the case in which the complementary component is competitively supplied, and in which innovation is important. We explore ways in which the...
