摘要

本文使用Azar(2006)最近提出的一种方法,报告了相对风险厌恶系数的估计。与他的工作相反,他使用了1926年至2002年期间美国股票回报数据的完整信息。此外,采用自举法估计了相关的不确定性。得到接近3.5的点估计。然而,从1.4到7.1,95%置信区间很宽。

Estimating the uncertainty of relative risk aversion
This note reports estimates of the coefficient of relative risk aversion, using a method recently proposed by Azar (2006). In contrast to his work, the complete information of US stock return data over the period 1926 to 2002 is utilized. Moreover, a bootstrap procedure is applied to estimate the associated uncertainty. Point estimates close to 3.5 are obtained. However, ranging from 1.4 to 7.1, the 95% confidence interval is wide.
