The paper investigates both quantity and price oligopoly games in markets with a variable number of managerial and entrepreneurial firms which defines market structure. Following Vickers (Economic Journal, 1985) which establishes an equivalence between the equilibrium under unilateral delegation...

Vertical integration in an environment without foreclosure, or more generally without any mechanisms that restrict competition among firms, and subsidization of firms' production are two separate mechanisms that raise consumer welfare, and both have been proposed as antidotes to certain aspects...

We examine both quantity and price competition between a number of profit-maximizing firms and a state-controlled enterprise (SCE). The objective function of the latter is strategically defined by a welfare-maximizing government which weighs the SCE’s profits relative to consumer surplus and...

Two well-known mechanisms for enhancing managers' accountability are yardstick competition and internal monitoring. Yardstick competition puts managers in direct competition when firms make decisions for re-appointment (Tirole, 2006). Monitoring is used by firms to detect managers' rent-seeking...

In a context of product innovation, we study two-part tariff licensing between a patentee and a potential rival which compete in a differentiated product market characterized by network externalities. The latter are shown to crucially affect the relative profitability of Cournot vs. Bertrand...

We describe a spatial duopoly in a Hotelling model with quadratic transportation costs where consumers are distributed according to a symmetric density whose degree of concentration is variable. By solving the two-stage game in prices and locations as a function of the concentration index, we...

It is widely believed that vertical integration in an environment without foreclosure, or more generally without any mechanism that restricts competition among firms, raises the welfare of consumers. In this paper we show that this can be overturned in a standard setting. We consider a vertical...

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...
