In this paper a discrete choice model is suggested which generates unambiguously lower prices, if oligopolists discriminate by price. In a setting of two groups of consumers and two firms this is due to a different ranking of the elasticity of demand of the two groups by the two firms. Here,...

Using a model with switching costs it is shown that firms may have an incentive to set up a new firm supplying to the same market under quite general conditions. The new firm attracts some market share of the founding firm. The start up firm is thus an act of cannibalization. Moreover, entry of...

In an oligopoly model with switching costs firms have no incentive to discriminate by price (third degree), if the environment is symmetric. This is partly due to the fact that prices decrease unambiguously with price discrimination. In an asymmetric environment a firm enjoying some advantage...

Commons and Anticommons problems are the consequence of symmetric structural departures from a unified conception of property. In this paper, we endeavor to provide a dual model of property, where commons and anticommons problems are the consequence of a lack of conformity between use and...

This paper develops a general model of anticommons fragmentation in property. To this end, we differentiate between different forms of property fragmentation. With the use of several functionally related examples, we consider the equilibria obtained under different scenarios. The various...

Diese Arbeit quantifiziert Verzerrungen, die sich bei der Verwendung von Daten aus der IAB-Beschäftigtenstatistik in Analysen von Betriebsgründungen und -schließungen ergeben können. Wir zeigen, daß bisherige Studien von Gründungs- und Schließungsdaten ausgegangen sind, die im Mittel...

Both M&A and innovation are instruments for growth and competitive advantage.Therefore they are fundamental to each firm’s competitive strategy. Usually, both instrumentshave been studied separately, but much less in conjunction. This is unfortunate as bothprocesses - the process of innovation...
