英文摘要:
This work presents an asset pricing model that under rational expectation equilibrium perspective shows how, depending on risk aversion and noise volatility, a risky-asset has one equilibrium price that differs in term of efficiency: an informational efficient one (similar to Campbell and Kyle (1993)), and another one where price diverges from its informational efficient level. The former Pareto dominates (is dominated by) the latter in presence of low (high) market risk perception. The estimates of the model using S&P 500 Index support the theoretical findings, and the estimated inefficient equilibrium price captures the higher risk premium and higher volatility observed during the Dot.com bubble 1995--2000.

中文摘要:
这项工作提出了一个资产定价模型,在理性预期均衡视角下,该模型显示了风险资产如何根据风险规避和噪声波动性,具有一个在效率方面不同的均衡价格:一个信息有效的均衡价格(类似于Campbell和Kyle(1993)),以及另一个价格偏离其信息有效水平的均衡价格。在存在低(高)市场风险感知的情况下,前者主导(被后者主导)。使用标准普尔500指数对模型进行的估计支持了理论发现,估计的无效均衡价格反映了Dot期间观察到的更高风险溢价和更高波动性。1995年到2000年。
