现金异质性与货币政策的派息渠道

Cash Heterogeneity and the Payout Channel of Monetary Policy
The Journal of Finance · 2026 · ALTAN PAZARBAŞI

中文摘要

本文提供了新的经验证据:面对扩张性货币政策冲击,现金充裕的企业具有更高的股权派息和更高的股价。尽管企业对货币政策的现金流、投资和信贷反应较弱,股价仍会上升。我在一个异质性企业的新凯恩斯模型中对此经验证据加以解释,在该模型中企业以现金和股权发行来为投资融资。货币宽松削弱了预防性现金需求,使现金充裕的企业将多余资金最优地分配给股东。由于派息具有顺周期性,现金充裕的企业在扩张期获得更高的回报。我的发现凸显了货币政策影响资产价格的一条派息渠道。

Abstract

ABSTRACT This paper provides novel empirical evidence that cash‐rich firms have higher equity payouts and higher stock prices in response to expansionary monetary policy surprises. Stock prices rise despite weak cash‐flow, investment, and credit responses to monetary policy. I rationalize the empirical evidence in a heterogeneous‐firm New Keynesian model where firms finance investment with cash and equity issuance. Monetary easing weakens precautionary cash demand, leading cash‐rich firms to optimally allocate excess funds to shareholders. Since payouts are procyclical, cash‐rich firms earn higher returns in expansionary periods. My findings highlight a payout channel through which monetary policy impacts asset prices.
