On the coincidence of cores and consistent distributions in mixed economic systems (Q1595527)

The author analyze the coalition stability of consistent distribution in mixed economic systems with nonlinear budget constraints. The economy comprises two markets. The first is characterized by fixed prices, a government rationing and material rationing. The second is a Walras economy (flexible prices, market clearing). The main result of this paper is the generalization of the Aumann theorem on the coincidence of cores and Walrasian equilibria. In this paper, the coincidence occurs under a strong assumption (A): When there is a government order then there is rationing. From the economic point of view, this result is easily understandable.
