Efficiency arguments explain why commercial intermediaries exist and will continue to be involved in the exchanges despite the spread of digital networks. Commercial intermediaries provide producers and consumers with a set of information, logistic, securization and insurance (and liquidity)...

This article presents the results of a study on buyer-supplier control in the manufacturing industry based on six case studies. Four buyer-supplier control configurations are proposed in a matrix according to the reciprocal dependence between the buyer and its suppliers. For each configuration,...

Considering the growing externalisation of strategic activities, the problem of the control of buyer-supplier relationships is crucial. Therefore, researchers usually propose modes of control that are adapted to various environments. However, the organisations are often considered as “black...

We prove the existence of the maxmin of zero-sum recursive games with one sided information.

We investigate a two-player zero-sum stochastic differential game in which the players have an asymmetric information on the random payoff. We prove that the game has a value and characterize this value in terms of dual viscosity solutions of some second order Hamilton-Jacobi equation.

We consider the asymptotic value of two person zero sum repeated games with general evaluations of the stream of stage payoffs. We show existence for incomplete information games, splitting games and absorbing games. The technique of proof consists in embedding the discrete repeated game into a...

The motivation of this paper comes from repeated games with incomplete information and imperfect monitoring. It concerns the existence, for any payoff function, of a particular equilibrium (called completely revealing) allowing each player to learn the state of nature. We consider thus an...
