Macroeconomic Volatilities and Long-Run Risks of Asset Prices
扩展了长期风险模型,引入长期和短期两种波动成分,以解释股票市场风险溢价、利率水平、股息收益率可预测性以及方差风险溢价期限结构等特征,对金融学者和从业者有参考价值。
In this paper, motivated by existing and growing evidence on multiple macroeconomic volatilities, we extend the long-run risks model by allowing both a long- and a short-run volatility components in the evolution of economic fundamentals. With this extension, the new model not only is consistent with the volatility literature that the stock market is driven by two, rather than one, volatility factors, but also provides significant improvements in fitting various patterns, such as the size of market risk premium, the level of interest rate, degree of dividend yield predictability, and the term structure of variance risk premiums, of both the equity and option data.
