This paper develops a general model of anticommons fragmentation in property. Using several related examples, we consider the equilibria obtained under different scenarios. The various illustrations are later utilized to develop a model of fragmented property. The model reveals that the private...

[fre] On analyse dans ce papier les choix de localisation, les offres de salaires et les demandes d'inputs de deux entreprises qui échangent des inputs intermédiaires et se concurrencent sur un marché spatial du travail. Le concept de sous-jeu parfait dans un jeu à plusieurs étapes de...

Proponents of RPM argue that RPM helps to sustain a high level of service at the point of sale and that such a high level is efficient. This paper provides a simple model which leads to the following conclusions: 1) RPM may increase or decrease the level of service. 2) Whether the service level...

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...

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...

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...
