摘要

继 Hansen（1939 年）之后，我们在一个大型企业层面面板上使用贝叶斯多层次（"混合效应"）模型来分离自主投资需求的长期下降，并检验其原因。企业层面的回归结果表明，投资放缓是自 1998 年以来 21 个发达经济体企业的长期特征，并一直持续到现在（2020 年）。我们利用集团层面（"宏观"）的回归，试图解释企业自主投资需求长期下降的原因。我们发现，相对投资机会的短缺--正如最初的 "世俗停滞论"--可以解释这种世俗性放缓中 40% 的变化。

Testing for secular stagnation in investment rates using a Bayesian multilevel model

Following Hansen (1939), we use a Bayesian multilevel (‘mixed effects’) model on a large firm-level panel to isolate the secular decline in autonomous investment demand and test for causes of it. Our firm-level regression shows that the investment slowdown is a long-standing feature across firms in 21 advanced economies since 1998 and continuing until the present (2020). Using a group-level (‘macro’) regression, we try to explain firms’ estimated secular decline in autonomous investment demand. We find that a shortage of relative investment opportunities – as per the original secular stagnation thesis – explains 40% of the variation in this secular slowdown.
