Modelling emerging market risk premia using higher moments
研究了在资本资产定价模型中引入偏度和峰度等高阶矩对新兴市场的增量价值，发现加入协偏度和协峰度等系统风险能比传统均值-方差模型更好地解释新兴市场收益。
The purpose of this paper is to assess the incremental value of higher moments in modelling capital asset pricing models (CAPMs) of emerging markets. Whilst it is recognized that emerging markets are unlikely to yield sensible results in a mean-variance world, the high skewness and kurtosis present in emerging markets returns make our assessment potentially interesting. Generalized method of moments (GMM) is used for the estimation. We also present new versions of higher-moment market models of the data-generating process of the individual emerging markets and use these to identify model parameters. We find some evidence that emerging markets are better explained with additional systematic risks, such as co-skewness and co-kurtosis, than the conventional mean-variance CAPM.
