本文提出了一个研究动态经济中不同信念的一般框架。在这个一般框架内,中央计划器一般等式的特征证明是非常容易导出的,并导致了一系列有趣的应用。我们表明,对于一个拥有不同信仰的对数投资者的经济,理性的过度自信是可以预期的;有效地模拟了贸易量效应;凯恩斯主义的“选美比赛”可以建模和分析;泡沫和崩溃自然产生。我们指出,代理接收私有信息的模型可以形式化地看作是不同信念的模型。

英文摘要:
This paper presents a general framework for studying diverse beliefs in dynamic economies. Within this general framework, the characterization of a central-planner general equilbrium turns out to be very easy to derive, and leads to a range of interesting applications. We show how for an economy with log investors holding diverse beliefs, rational overconfidence is to be expected; volume-of-trade effects are effectively modelled; the Keynesian `beauty contest' can be modelled and analysed; and bubbles and crashes arise naturally. We remark that models where agents receive private information can formally be considered as models of diverse beliefs.
