摘要/Abstract

摘要： 收益率与波动率之间的关系(风险补偿)在金融资产定价和风险管理中至关重要，但二者之间的研究却一直没有定论。金融理论表明为正向关系，但实证却往往得到相反的结果。众所周知，尖峰厚尾以及负偏是收益率的典型特性。这些内在属性对风险补偿无疑有着重要的影响。本文研究表明，收益率的负偏和尖峰厚尾会导致风险补偿系数减小，进而导致风险补偿系数在实证当中的不确定性。虽然各个行业的夏普比率相差无几，我国股票市场的第“I”类、第“II”类风险补偿以及风险价格在不同行业之间存在较大的差异，且三者随着投资期限的增长，分别有下降、上升和轻微上升的趋势。

关键词: 风险补偿；偏度；峰度；GARCH；SGT分布；

Abstract: As the first fundamental law of finance, the relationship between return and volatility (risk premium) is far from being conclusive,the so-called “Return-Volatility Puzzle”. Financial theory shows a positive relationship, but empirical results tend to be opposite. As we all know, kurtosis, thick tail and negative skewness aretypical featuresof returns. These inherent and endogenous attributes undoubtedly have an important impact on risk compensation.Besides, the non-normal or asymmetrical distributional features can produce ineffectiveness or inaccuracy for those estimators of coefficients with wrong distributional assumptions regardless of linear or nonlinear tests of the relationship.

Key words: risk premium; skewness; kurtosis; GARCH; SGT distribution
