摘要|Abstract
这篇论文运用实验经济学的方法探讨了实物资产的泡沫问题。在本文的实验设定中,参与者需要重复进行实物资产的购入并进行生产的决策,实验过程中实物资产的基础价值保持不变。实验设计参考了Holt et al(2017)关于风险资产价格泡沫的论文和Holt and Shobe (2016)关于碳排放权市场的论文。我们对之前论文的创新在于,(1)构造了资产供给不变或趋紧的设置(2)构造了资产基础价值不变的设置(2)在实验设计中构造的实物资产与金融资产有不同的属性。
我们发现,实物资产的供给不变的情况下,其价格会产生泡沫,但泡沫会很快破灭;当实物资产的供给逐渐减少时,参与者无法进行理性的跨期平滑使用,资产价格呈现缓慢上涨至暴涨的现象。根据实验中收集参与者对价格的预期数据,本文发现预期与实际价格的差值驱动了资产价格的上涨和下跌。本文同时还发现,如果允许参与者跨期进行实物资产的借还,将有利于平抑资产的价格泡沫。
