英文摘要:
This paper investigates the ex-post core and its relationships to the fine core and the set of rational expectations equilibrium allocations in an oligopolistic economy with asymmetric information, in which the set of agents consists of some large agents and a continuum of small agents and the space of states of nature is a general probability space. We show that under appropriate assumptions, the ex-post core is not empty and contains the set of rational expectations equilibrium allocations. We provide an example of a pure exchange continuum economy with asymmetric information and infinitely many states of nature, in which the ex-post core does not coincide with the set of rational expectations equilibrium allocations. We also show that when our economic model contains either no large agents or at least two large agents with the same characteristics, the fine core is contained in the ex-post core.

中文摘要:
本文研究了信息不对称寡头垄断经济中的事后核心及其与精细核心和理性预期均衡配置集的关系,其中代理集由一些大代理和一系列小代理组成,自然状态空间是一般概率空间。我们证明,在适当的假设下,事后核心不是空的,并且包含一组理性预期均衡配置。我们提供了一个纯交换连续统经济的例子,该经济具有不对称信息和无限多个自然状态,其中事后核心与理性预期均衡配置集不一致。我们还表明,当我们的经济模型不包含大型代理或至少包含两个具有相同特征的大型代理时,后核中包含细核。
