This paper provides a complete characterization of equilibria in a game-theoretic version of Rothschild and Stiglitz's (1976) model of competitive insurance. I allow for stochastic contract offers by insurance firms and show that a unique symmetric equilibrium always exists. Exact conditions...

The trade-off between the costs and benefits of disclosing a firm's private information has been the object of a vast literature. The absence of incentives to share information on a common market demand prior to competition has been advocated to interpret information sharing as evidence of...

The paper presents an economic model of interaction between cricket boards, players and international club-line games sponsors like ICL or IPL. It attempts to capture the inherent conflict between such games and country-line games traditionally organized by cricket boards. It identifies the...

Seitdem sich im Lauf des letzten Jahres die Rohölpreise nahezu halbiert haben, wird viel darüber spekuliert, wie deren zukünftiger Verlauf sein könnte. In seinem Kommentar befasst sich Georg Erber, European Productivity Research Center, mit dem Einfluss der OPEC und der USA auf die Erdölpreise.

Taking as a reference a model in which there are a public firm, a national private firm and a foreign private one, it is analyzed both mergers sustainability and their relative effects on welfare. It is proved that the merger between the public firm and either the national or the international...

Eine wichtige Ursache für den Anstieg des Ölpreises seit Mitte der 90er Jahre ist die stetig steigende Ölnachfrage. Dazu hat in letzter Zeit das starke Wirtschaftswachstum in den Schwellenländern wesentlich beigetragen. Aktuell dürften die Unruhen in Nordafrika den Ölpreis weiter nach oben...

Random utility models are widely used to study consumer choice. The vast majority of applications assume utility is linear in consumption of the outside good, which imposes that total expenditure on the subset of goods of interest does not affect demand for inside goods and restricts demand...

This article presents a new approach to analyze the equilibrium set of symmetric, differentiable games by separating multiple symmetric equilibria and asymmetric equilibria. This separation allows the investigation of, for example, how various parameter constellations affect the scope for...
