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 analyze an equilibrium choice of a product quality within a supply chain consisting of a manufacturer and a supplier. A quality of an intermediate good is private information of the supplier and determines the quality of a final product. The manufacturer holds all bargaining power and...

Suppliers often make proactive investments in capacity to strategically position themselves to win a contract with a monopolist buyer. Such investments reduce the suppliers' variable costs of serving the buyer's demand. We show that an auction mechanism does not always benefit the...

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....

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...

In systems industries, combinations of components are consumed together to generate user benefits. Arrangements among component providers sometimes limit consumers’ ability to mix and match components, and such exclusive arrangements have been highly controversial. We examine the competitive...

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...

This article presents a stochastic dynamic Generalized Nash-Cournot model to describe the evolution of the natural gas markets. The major gas chain players are depicted including: producers, consumers, storage, and pipeline operators, as well as intermediate local traders. Our economic structure...

We analyze price competition between two brands. Buyers consist of switchers and two segments of customers with limited brand loyalty. We identify a unique symmetric mixed-strategy price equilibrium and find that competition is most relaxed when there exists some switchers.

The spectrum for third generation (3G) mobile communications for the German market was alloted to operators by means of an auction. This resulted in a highly competitive outcome: six operators were given rights to provide 3G services. Government revenues from this auction were a staggering EUR...
