Abstract We introduce new notions of bargaining set for mixed economies which rest on the idea of generalized coalitions (Aubin, 1979) to define objections and counter-objections. We show that the bargaining set defined through generalized coalitions coincides with competitive allocations under assumptions which are weak and natural in the mixed market literature. As a further result, we identify some additional properties that a generalized coalition must satisfy to object an allocation.

广义联盟和谈判集

摘要 我们为混合经济引入了新的讨价还价概念，该概念基于广义联盟（Aubin，1979）的概念来定义反对和反反对。我们表明，通过广义联盟定义的讨价还价集与混合市场文献中弱且自然的假设下的竞争性分配相吻合。作为进一步的结果，我们确定了广义联盟必须满足的一些附加属性才能反对分配。
