Sustainability in a Multiproduct and Multiple Agent Contestable Market
Iehlé, Vincent - Université Paris-Dauphine (Paris IX) - 2009
We prove that a natural monopoly can set subsidy free pricing and sustainable pricing schedules in general economic environment. The setting is a multiproduct and multiple agent contestable market where demands are elastic and where rivals can enter the sub-markets composed by a set of the...

Stable pricing in monopoly and equilibrium-core of cost games.
Iehlé, Vincent - Université Paris-Dauphine (Paris IX) - 2004
We prove the existence of subsidy free and sustainable pricing schedule in multiproduct contestable markets. We allow firms to discriminate the local markets that are composed by a set of the products line and a set of agents. Results are obtained under an assumption of fair sharing cost and...

The lattice structure of the S-Lorenz core
Iehlé, Vincent - Université Paris-Dauphine (Paris IX) - 2015
For any TU game and any ranking of players, the set of all preimputations compatible with the ranking, equipped with the Lorenz order, is a bounded join semi-lattice. Furthermore, the set admits as sublattice the S-Lorenz core intersected with the region compatible with the ranking. This result...
