The paper analyzes a Cournot model with two types of firms: Maximizers of profits and maximizers of relative payoffs. It is shown that the equilibrium is located somewhere between the regular Cournot-Nash equilibrium and the competitive Walrasian (or Bertrand-) equilibrium.

The paper proves that monopolistic price discrimination increases output under conditions of constant demand elasticity. The demonstration is simpler than that of Formby, Layson and Smith (1983)

This article considers a model of spatial competition where firms and consumers are located in a semicircular space rather than in the whole circle (Salop's model) or the linear city (Hotelling's model), under the assumptions of both, convex and concave, transportation costs. The paper tries to...

This paper studies the question of entry in the circular city model when the pre-entry market structure involves local monopolies. In contrast with Salop (1979), we show that the unit profit rate of incumbent monopolists is strictly positive and bounded above. The upper bound decreases with the...

In this note we examine four standard multi-unit sealed-bid auctions in the presence of synergy. The structure of the equilibrium bidding strategy under each rule is quite intuitive. Whether the equilibrium involves "bundle-bidding" or "separating-bidding" strategy depends on the presence of the...

In this note we consider a general equilibrium model with oligopolistic competition between firms who ignore the feedback effect of their dividend payments on demand. The outcome of this competition coincides with the perfectly competitive equilibrium solution, provided that firms have identical...

We examine firms' preferences for product differentiation when a firm has a demand-side and/or a cost-side advantage over its competitor. We show that if the magnitude of these advantages is small, then both firms prefer more differentiated products. However, if the magnitude of demand-side...

In an example with monopoly final and intermediate goods firms and substitutable primary and intermediate inputs, it is shown that there exist turnover taxes that yield more revenue than any feasible value-added tax. Second, simultaneously higher welfare, revenue and output are possible with the...

In a laboratory experiment, the voluntary provision of public goods is investigated when there is probabilistic uncertainty about the monetary return from production of the public good. After group members make their provision decisions, the return is drawn from an exogenously determined...
