构建贝叶斯因子复制模型,发现多数资产定价因子可被复制、可归为13个主题且多数在样本外93国数据中仍有效,反驳了金融学存在复制危机的观点。

Abstract

ABSTRACT Several papers argue that financial economics faces a replication crisis because the majority of studies cannot be replicated or are the result of multiple testing of too many factors. We develop and estimate a Bayesian model of factor replication that leads to different conclusions. The majority of asset pricing factors (i) can be replicated; (ii) can be clustered into 13 themes, the majority of which are significant parts of the tangency portfolio; (iii) work out‐of‐sample in a new large data set covering 93 countries; and (iv) have evidence that is strengthened (not weakened) by the large number of observed factors.
