Die Erhöhung der Benzinpreise findet in der Öffentlichkeit viel Beachtung. Das Bundeskartellamt geht in Deutschland von einem marktbeherrschenden Oligopol der Mineralölgesellschaften aus. Wettbewerbsrechtliche Maßnahmen greifen jedoch nicht, weil der Markt sehr volatil ist und direkte...

We investigate the welfare effect of union activity in a relatively new oligopoly model, the Cournot-Bertrand model, where one firm competes in output (a la Cournot) and the other firm competes in price (a la Bertrand). The Nash equilibrium prices, outputs, and profits are quite diverse in this...

This study derives pure strategy Bertrand equilibria in a duopoly in which two firms produce a homogeneous good with convex cost functions and seek to maximize the weighted sum of their absolute and relative profits. The study shows that there exists a range of equilibrium prices in duopolistic...

Trotz schrittweiser Erfolge bei der Liberalisierung der europäischen Elektrizitätsmärkte lässt die Wettbewerbsintensität auf den Großhandelsmärkten in vielen Ländern noch zu wünschen übrig. Dementsprechend sind die Preise im Verhältnis zum wettbewerblichen Referenzmaßstab zu hoch....

This paper tests the hypothesis that a (partial) reason why cartels - collective but costly and non-binding price agreements - lead to higher prices in a Bertrand oligopoly could be because of a selection effect: decision-makers who are willing to form price agreements are more likely to be less...

In a domestic market, a duopoly produces a homogeneous final good, pollution, pollution abatement, and R&D, which reduces abatement cost. One of the firms (foreign) has superior technology. The government regulates the duopoly by levying a pollution tax to maximize domestic welfare. We consider...

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...

In this article, we consider technology leaders (which are innovators) and technology followers (which are non-innovators) to provide a new theoretical explanation for the well-cited empirical evidence of an inverted-U relationship between competition and aggregate innovation. We consider a...

The standard approach to nominal illusion in Economics sees it as a transitory phenomenon, as economic agents eventually see through the nominal veil, making the right choices. Recent empirical studies suggest that money illusion may persist, distorting real prices in a variety of economic...
