DEPARTMENT OF ECONOMICS WORKING PAPER SERIES Spying in Multi-market Oligopolies
We consider a multimarket framework where a set of firms compete on two interrelated oligopolistic markets. Prior to competing in these markets, firms can spy on others in order to increase the quality of their product. We characterize the equilibrium espionage networks and networks that maximize social welfare under the most interesting scenario of diseconomies of scope. We find that in some s...
متن کاملExtending Networks of Collaboration to Multi-market Oligopolies
In this article, we extend the Goyal and Joshi's model (2003) of network of collaboration in oligopoly to multi-market situations. We examine the incentive of firms to form links and the architectures of the resulting networks in this setting. We also present some results on efficient networks.
متن کاملStrategic Interactions in Two-Sided Market Oligopolies
Strategic interactions between two-sided platforms depend not only on whether their decision variables are strategic complements or substitutes as for one-sided firms, but also -and crucially soon whether or not the platforms subsidize one side of the market in equilibrium. For example, with prices being strategic complements across platforms, we show that a cost-reducing investment by one firm...
متن کاملMultimarket Oligopolies with Restricted Market Access
We study the existence of Cournot equilibria in multimarket oligopolies under the additional restriction that every firm may sell its product only to a limited number of markets simultaneously. This situation naturally arises if market entry is subject to a valid license and each firm holds a fixed number of licenses only, or, equivalently, if the firms’ short-term assets only suffice to serve ...
متن کاملA Stable Market Structure as the Solution for Cournot Oligopolies
A stable market structure is a partition of the firms in an industry such that there is no incentive for any breakups or mergers. Characterizing such stability requires an endogenization of both the core and Cournot equilibrium as well as all hybrid equilibria. This paper solves for the stable partitions in a general oligopoly by providing a tractable condition: a partition is stable if and onl...
