Strategic behavior and partial cost sharing. (Q1399523)

This is an interesting contribution to the study of the games in which the players mainly compete, but nonetheless collaborate on some subsidiary activities. Thus, starting from natural hypotheses ensuring that the cost-sharing games have non-empty cores, the authors show how the Lagrange multipliers yield core solutions, with significant corresponding consequences and examples, they present the regional oligopoly and they establish the existence and the characterization of the appropriate equilibria under pertinent selective references.
