Estimating and Testing Long-Run Risk Models: International Evidence
利用10个发达国家的宏观经济和金融数据，采用贝叶斯方法估计和检验长期风险模型，发现全球长期消费因子驱动各国股票收益，支持长期风险、时变偏好冲击和随机贴现因子的逆周期性。
We estimate and test long-run risk models using international macroeconomic and financial data. The benchmark model features a representative agent who has recursive preferences with a time preference shock, a persistent component in expected consumption growth, and stochastic volatility in fundamentals characterized by an autoregressive gamma process. We construct a comprehensive data set with quarterly frequency for 10 developed countries and employ an efficient likelihood-based Bayesian method that exploits up-to-date sequential Monte Carlo methods to make full econometric inference. Our empirical findings provide international evidence in support of long-run risks, time-varying preference shocks, and countercyclicality of the stochastic discount factor. We show the existence of a global long-run consumption factor driving equity returns across individual countries. This paper was accepted by Lukas Schmid, finance. Funding: A.
