This paper analyzes a simple, repeated game of simultaneous entry and pricing. We report a surprising property of the symmetric equilibrium solution: If the number of potential competitors is increased above two, the market breaks down with higher probability, and the competitive outcome becomes...

This paper shows that vertical foreign direct investment will reduce prices but the aggregate welfare effect is unambiguously positive only under free market entry. Using a standard model of imperfect competition, we develop this result by considering two different cases. In the first case, the...

The central purpose of this paper is to examine firms' vertical integration decisions as a consequence of strategic choices within an explicit market environment. I show that a unique equilibrium number of unintegrated downstream firms exists when the intermediate-good market is imperfectly...

Die Arbeit untersucht den von der ?Arbeitgruppe Netznutzung Strom der Kartellbehörden des Bundes und der Länder? vorgeschlagenen Subtraktionstest, mit dessen Hilfe missbräuchlich überhöhte Netznutzungsentgelte für die Durchleitung von Strom identifiziert werden sollen. Dabei kommen wir zu...

According to Stigler (1951), vertical disintegration should be the typical development in growing industries, vertical integration in declining industries. The basic argument is that firms will spin off production stages subject to increasing returns to scale in response to market growth. This...

The paper examines the welfare effects of the development of an intermediate market. For this purpose I develop a model where such a market may arise endogenously. If integrated and unintegrated firms coexist in equilibrium, consumers do not benefit from the emergence of an intermediate market....
