Private information, transferable utility, and the core

Research Article


We consider transferable-utility, cooperative games, featuring differently informed players. Parties can exchange endowments or undertake joint production, but not pool information. Coalitional contracts must therefore comply with members’ private information. Qualitatively different shadow prices then arise: some for material endowments, others for knowledge. We focus on computable core solutions, generated by shadow prices. Such solutions obtain under standard regularity assumptions.
