Ein Modell der Netzwerkeffekte in der Software-Industrie

Gröhn, Andreas - Institut für Weltwirtschaft (IfW) - 1997

Computer-owners combine complementary goods to a computer-system. They exchange data with others and between different applications. These interdependencies lead to three different network effects, which are explained in the framework of Hotelling models. In the framework of a one-dimensional...

An Examination of the Efficiency, Foreclosure, and Collusion Rationales for Vertical Takeovers

Shenoy, Jaideep - In: Management Science 58 (2012) 8, pp. 1482-1501

We investigate the efficiency, foreclosure, and collusion rationales for vertical integration in a large sample of … vertically related takeovers. The efficiency rationale, as discussed under the transaction cost economics and property rights … with an efficiency enhancing rationale. <i>This paper was accepted by Brad Barber, finance.</i> …

Who Integrates?

Bühler, Stefan; Schmutzler, Armin - C.E.P.R. Discussion Papers - 2003

We examine vertical backward integration in oligopoly. Analysing a standard linear Cournot model, we find that for wide parameter ranges (i) some firms integrate, while others remain separated, and (ii) efficient firms are more likely to integrate vertically. Adopting a reduced-form approach, we...

Asymmetric Vertical Integration

Buehler, Stefan; Schmutzler, Armin - In: Advances in Theoretical Economics 5 (2005) 1, pp. 1164-1164

We examine vertical backward integration in a reduced-form model of successive oligopolies. Our key findings are: (i) There may be asymmetric equilibria where some firms integrate and others remain separated, even if firms are symmetric initially; (ii) Efficient firms are more likely to...
