Abstract

             independent sources choose their provider depending on the perceived costs associated with each provider. The perceived cost is the sum of the price and quality of service proposed by the provider coefficiented by the source sensitivity to the quality of service. The source chooses the smallest cost provider or refuses to subscribe if all the perceived costs are above her maximum admissible opportunity cost. First, we detail the market segmentation between the providers as function of the quality of service sensitivity. Then, we prove that in case where coalitions emerged and under defensive equilibria, the game characteristic function would be submodular meaning that the Shapley value would be a fair and stable way to share the grand coalition revenue.

Keywords: cooperative game Shapley value
