Uncertainty in Information Market Games

A new product can be produced and sold in a market thanks to the entrance of a patent holder into the market. This market is divided into submarkets controlled by only some firms and the profit attainable in each submarket is uncertain. In this paper, this situation is studied by means of cooperative games under interval uncertainty. We consider different ways of allocating the interval profit among the firms. One of these is the interval [Formula: see text]-value, which is defined for interval games satisfying some conditions. Efficient interval solutions in terms of the market data are provided.
