We present an agent-based model of a multi-tier energy market including gas shippers, electricity generators and retailers. We show how reward interdependence between strategic business units within a vertically integrated firm can increase its profits in oligopolistic energy markets. The...

We show that merger can be profitable and welfare enhancing here, even though it is not profitable in a laissez-faire economy. A key element is...

Competition in some product markets takes the form of a contest. If some firms cooperate in such markets, they must decide how to allocate effort on each of their products and whether to reduce the number of their products in the competition. We show how this decision depends on the convexity...
