The aim of this paper is to extend Hamilton and Slutsky's (1990) endogenous timing game by including the possibility for players to cooperate. At an initial stage players are assumed to announce both their purpose to play early or late a given duopoly game as well as their intention to cooperate...

In this paper we review a number of coalitional solution concepts for the analysis of the stability of cartels and mergers under oligopoly. We show that, although so far the industrial organization and the cooperative game-theoretic literature have proceeded somehow independently on this topic,...

The aim of this paper is to study the welfare e¤ects of consumer cooperatives in mixed oligopoly markets. We show that under decreasing returns to scale and su¢ ciently high market competition these …rms can contribute more to social welfare when acting on behalf of all consumers rather than...

The main aim of this paper is to study the propensity of consumer cooperatives (Coops)to use incentive schemes in situations of strategic interaction with profit-maximizing …rms (PMFs). Our model provides a reason why Coops are less prone than PMFs to pay variable bonuses to their managers. We...

This paper presents synthetically some recent developments in the theory of coalition and network formation. For this purpose, some major equilibrium concepts recently introduced to model the formation of coalition structures and networks among players are briefly reviewed and discussed. A few...

This paper revisits a particular behaviour for firms competing in imperfect competitive markets, underlying the well known model of kinked demand curve. We show that under some symmetry and regularity conditions, this asymmetric behaviour of firms sustains monopoly pricing, and possesses...

The object of the work is to perform the global analysis of the Cournot duopoly model with isoelastic demand function and unit costs, presented in Puu (1991). The bifurcation of the unique Cournot fixed point is established, which is a resonant case of the Neimark-Shacker bifurcation. New...

This article considers a Cournot duopoly under an isoelastic demand function and cost functions with built-in capacity limits. The special feature is that each fi…rm is assumed to operate multiple plants, which can be run alone or in combination. Each …firm has two plants with different...

We propose an duopoly game where quantity-setting firms have incomplete information about the demand function. In each time step, they solve a profit maximization problem assuming a linear local approximation of the demand function. In particular, we construct an example using the well known...
