We analyze the effect of price caps on equilibrium production and welfare in oligopoly under demand uncertainty. We find that high price caps always increase production and welfare as compared to the situation without price cap. Price caps close to marginal cost may lead to zero production,...

This paper establishes sufficient conditions for the existence of a stable coalition structure in the "coalition unanimity" game of coalition formation, first defined by Hart and Kurz (1983) and more recently studied by Yi (1997, 2000). Our conditions are defined on the strategic form game used...

A Cournot-Nash oligopoly model is used to study self-regulation of industrial pollution emissions. Consumers have environmental preferences such that demand is decreasing in their knowledge of industrial emissions. Symmetric firms choose output and emission control input levels. Under...

Zusammenfassung Dieser Aufsatz beschäftigt sich mit dem Beitrag von Seitz und Stackelberg zur Oligopoltheorie. Stackelbergs Theorie der Preisführerschaft hat Seitz in seiner Dissertation aus dem Jahre 1965 aufgenommen. Der Autor gibt eine Zusammenfassung der Debatte in Deutschland zu Beginn...

Zusammenfassung Der Preisanpassungsprozess im Oligopol wird untersucht. Unter recht allgemeinen Voraussetzungen an die (lineare) Preis-Nachfrage-Funktionen der Akteure werden verschiedene Strategien diskutiert, wie z. B. die klassische Cournot-Nash-Lösung, die Launhardt-Hotelling-Strategie, die...

We show that if limit orders are required to vary smoothly, then strategic (Nash) equilibria of the double auction mechanism yield competitive (Walras) allocations. It is not necessary to have competitors on any side of any market: smooth trading is a substitute for price wars. In particular,...

This thesis develops an equilibrium framework for strategic exercise of geographical market entry option. The theoretical model analyses the impact of asymmetries of the competing firms such as follower entry barrier and asymmetric profitability on the optimal market entry timing and firm...

The purpose of this article is to analyze how the presence of a competitive fringe, composed by price taker firms, can affect the sustainability of collusive equilibria. Our starting point is that there exists a diffused misunderstanding about its strategical role as collusive minus factor. We...

We examine the interplay of endogenous vertical integration and costreducing downstream investment in successive oligopoly. We start from a linear Cournot model to motivate our more general reducedform framework. For this general framework, we establish the following main results: First,...

We present the results of an experiment on learning in a continuous-time low-information setting. For a Cournot oligopoly with differentiated products, a dominance solvable game, we find little evidence of convergence to the Nash equilibrium. In an asynchronous setting, play tends toward the...
