中文摘要

我们识别出货币政策向非金融企业传导的一条新渠道——僵尸贷款渠道。我们的研究发现,相较于其他企业,缺乏生存能力且生产率低下的僵尸企业受紧缩性货币政策的影响较小,原因是其信贷条件的收紧更为温和。我们以利率上升时永续续贷动机的增强来解释这一结果:贷款方面临向僵尸企业展期贷款以防止其违约的激励。强化银行资产负债表并遏制高风险放贷行为,有助于在金融条件收紧时减轻僵尸贷款行为。本文由金融领域编辑Tomasz Piskorski接收。补充材料:在线附录和数据文件可在https://doi.org/10.1287/mnsc.2024.07315获取。

Abstract

We identify a new channel in the monetary policy transmission to nonfinancial corporates—the zombie lending channel. Our findings show that unviable and unproductive zombie firms are less affected by contractionary monetary policy relative to other firms because of a more muted tightening in credit conditions. We rationalize this result with a strengthening in evergreening motives when interest rates rise: lenders face incentives to extend loans to zombies to prevent them from defaulting. Strengthening banks’ balance sheets and curbing risky lending behavior could help mitigate zombie lending practices when financial conditions tighten.
