The main objects here are Nash equilibria in spatial Cournot oligopolies when profits depend on coordinated distribution. Production is non-cooperative, but the subsequent transportation must be performed jointly to minimize costs. Cournot-Nash equilibria for this two-stage game with partial...

Taxation under oligopoly is analysed in a general equilibrium setting where the firms are large relative to the size of the economy and maximise the utility of their shareholders. It turns out that the model is an aggregative game, which simplifies the comparative statics for the effects of...

We analyze cooperative Cournot games with boundedly rational firms. Due to cognitive constraints, the members of a coalition cannot accurately predict the coalitional structure of the non-members. Thus, they compute their value following simple heuristics. In particular, they assign various...

The effects of partially cooperating firms are examined in N-firm oligopolies. The Herfindahl-Hirschmann Index is assumed to detect the violation of the antitrust regulation by the firms, and based on this assumption a piece-wise differentiable dynamic system can be developed. The firms stop...

In this paper, we use a partition function form game to analyze cartel formation among firms in Cournot competition. We assume that a firm obtains a certain cost advantage that allows it to produce goods at a lower unit cost. We show that if the level of the cost advantage is "moderate", then...

We study investments in R&D and the formation of R&D clusters of firms which are competitors in the market. In a three stage game, firms first decide on long-term R&D investment, then form research clusters according to the unanimity game introduced in Bloch(1995), and finally compete in...

In this paper I set forth an antitrust remedy for the oligopolistic pricing problem. Oligopoly pricing resembles a repeated prisoners' dilemma game. Each firm has an incentive to moderately lower its price and thus increase its sales at its competitors' expense. However, each firm knows that its...

We study a supply chain in which a consumer goods manufacturer sells its product through a retailer. The retailer undertakes promotional expenditures, uch as advertising, to increase sales and to compete against other retailer(s). The manufacturer supports the retailer’s promotional...

Investigating the strategic advantage of negatively interdependent preferences in action monotonic games, we derive characterizing conditions both for general action monotonic games and for the subclass of action monotonic games with spillovers. Examples demonstrate the generality of our...

This study investigates the impact of pre-play communication on the outcomes in Cournot duopoly and triopoly experiments, using both students and managers as subjects. Communication is implemented by two different devices, a ‘standardized-communication’ and a free-communication device. We...
