We investigate the differentiated duopoly and triopoly markets in which firms can choose to strategically delegate when the biased managers hold about the market demand incorrectly under Bertrand competition. Contrast to previous studies under duopoly, one firm chooses delegate, while the other...

We reconsider the endogenous choice of delegation to a manager by two down-stream firms in both a Cournot and a Bertrand vertical market with network effects. An upstream monopolist charges a two-part tariff for a crucial input. By applying the Nash solution in a centralized bargaining, we show...

We consider a model of price competition in a duopoly with product differentiation and network effects. The value of a good for a consumer is the sum of a common and an idiosyncratic component. The first captures the vertical dimension of quality, the second captures horizontal differentiation....

Online platforms, such as Google, Facebook, or Amazon, are constantly expanding their activities, while increasing the overlap in their service offering. In this paper, we study the scope and overlap of online platforms' activities, when they are endogenously determined. We model an expansion...

We study the effects of group identity on cooperation in experimental two-person strategic games. Our results show that in games of strategic complements, group identity only matters initially when a participant interacts with another participant of the same group by delivering more cooperative...

The seminal paper by Salant, Switzer and Reynolds (1983) showed that merger in a standard Cournot framework with linear demand and linear costs is not profitable unless a large majority of the firms are involved in the merger. However, many strategic aspects matter for firm competition such as...

This paper discusses a simultaneous market entry game between two firms with different fixed costs. This case is a typical application of mixed strategy equilibria. Conventional wisdom would suggest that the low-cost firm is more likely to enter the market. This presumption is wrong. Instead,...

This paper demonstrates that the Bertrand paradox does not hold if cost functions are strictly convex. Instead, multiple equilibria exist which can be Pareto-ranked. The paper shows that the Pareto-dominant equilibrium may imply profus higher than in Cournot competition or may even sustain...

Dieser Beitrag erweitert die Standardmodellierung der Literatur über Informationsaustausch zwischen Unternehmen bei Nachfrageunsicherheit und läßt sich vor allem auf Unternehmen in neuen Branchen oder in unsicheren Märkten anwenden ...

We analyze a market game where firms choose capacities under uncertainty about future market conditions and make output choices after uncertainty has unraveled. We show existence and uniqueness of equilibrium under imperfect competition and establish that capacity choices by strategic firms are...
