@article{(Open Science Index):https://publications.waset.org/pdf/14290, title = {Stability of Alliances between Service Providers}, author = {Helene Le Cadre}, country = {}, institution = {}, abstract = {Three service providers in competition, try to optimize their quality of service / content level and their service access price. But, they have to deal with uncertainty on the consumers- preferences. To reduce their uncertainty, they have the opportunity to buy information and to build alliances. We determine the Shapley value which is a fair way to allocate the grand coalition-s revenue between the service providers. Then, we identify the values of β (consumers- sensitivity coefficient to the quality of service / contents) for which allocating the grand coalition-s revenue using the Shapley value guarantees the system stability. For other values of β, we prove that it is possible for the regulator to impose a per-period interest rate maximizing the market coverage under equal allocation rules.}, journal = {International Journal of Mathematical and Computational Sciences}, volume = {4}, number = {6}, year = {2010}, pages = {678 - 693}, ee = {https://publications.waset.org/pdf/14290}, url = {https://publications.waset.org/vol/42}, bibsource = {https://publications.waset.org/}, issn = {eISSN: 1307-6892}, publisher = {World Academy of Science, Engineering and Technology}, index = {Open Science Index 42, 2010}, }
