We study endogenous coalition formation in contexts where individual (and group) payoffs depend on the entire coalition structure that might form. We capture potential interaction across coalitions by means of a partition function.

This paper studies a strategic market game where agents fragment their bids on different markets. Simple conditions for existence of an interior equilibrium point are provided. In equilibrium, all agents are active on the same markets and prices are identical across markets, so that all...

A two-stage game is used in this paper to model a long-run market with spatially separated producers and with multi-period demands: first, firmas simultaneously and independently invest their capacities; second, after capacities are set up in the first stage and made public, firms engage in a...

An oligopoly with spatially dispersed producers and consumers and with multi-period demands is modeled in this paper.

Long-run oligopolistic expansion behavior in an electricity supply market is modeled in this paper.

This is a preliminary version of a prospective book which springs from concerted effort among several researchers in the fiels of industrial economics. This chapter is devoted to the strategic role of information in oligopoly, and more broadlyn, in monotone games in general.

The endogeneity of equilibrium strategies makes modelling uncertainty about the behaviour of other economic players difficult. Recent developments in decision and game theory offer an opportunity to include strategic uncertainty as an explanatory variable in economic analysis. This paper...

Consider an oligopolistic industry where demand uncertainty resolves after at least one firm has engaged in production. Those firms who produce first behave as simultaneous leaders (co-leaders), whilst those who produce after demand becomes observable will be followers. Each follower simply...

In an oligopoly supergame, firms' actions in prices and quantities are subject to non-negativity constraints. These constraints can obstruct the practicability of optimal punishment (a la Abreu (1986), Lambson (1987), and Hackner (1996)) in sustaining tacit collusion. Noting that the prospect of...

In an oligopoly supergame, firms face an obvious technological constraint: the positivity of their production quantities. WE show that Lambson's (1987) result on "security-level punishment", that the single-period punishment makes the firm's discounted participation condition just bind, holds...
