摘要

分析了噪声信息聚集对投资的影响。市场不完善会产生内生租金，导致对上行风险的过度投资和对下行风险的投资不足。在部分均衡中，如果上行风险与投资的可扩展性相结合，这些低效率就会特别严重。在一般均衡中，股东集体提高单个公司价值的努力导致了一种新的外部性，这种外部性通过价格运作，放大了具有下行风险的投资扭曲，但抵消了具有上行风险的扭曲。(凝胶d21, d25, d83, g14, g32, g41)

Imperfect Financial Markets and Investment Inefficiencies

We analyze the consequences of noisy information aggregation for investment. Market imperfections create endogenous rents that cause overinvestment in upside risks and underinvestment in downside risks. In partial equilibrium, these inefficiencies are particularly severe if upside risks are coupled with easy scalability of investment. In general equilibrium, the shareholders’ collective attempts to boost value of individual firms leads to a novel externality operating through price that amplifies investment distortions with downside risks but offsets distortions with upside risks. (JEL D21, D25, D83, G14, G32, G41)
