谁承担成本:金融摩擦与劳动力买方压价

Who bears the cost: Financial frictions and labor markdown

中文摘要

我们提供了中国银行业集中度与劳动力买方压价之间存在关联的证据。利用涵盖中国银行分支机构分布与企业绩效的大规模数据集,我们发现,本地市场的金融摩擦导致企业层面的劳动力买方压价程度显著提高,但对企业的产品加成率和盈利能力影响甚微。这提示,企业在面临更高的融资成本时,会通过剥削劳动力将金融摩擦的影响转嫁到劳动力市场。这种金融摩擦的传导在低技能密集型企业或非国有企业中更为突出,而更高的劳动力流动性促进了这一传导过程。我们的研究发现凸显了金融摩擦在经济中的分配效应:最终承担金融摩擦成本的是劳动力,尤其是低技能劳动力,而非资本。

Abstract

We present evidence of a connection between bank concentration and labor markdown in China. Using a large dataset on bank branch distribution and firm performance in China, we document that financial friction in the local market leads to significantly higher firm-level labor markdowns but has little impact on firms’ product markup and profitability. This suggests that firms pass the impact of financial friction to the labor market by exploiting labor when faced with higher financial costs. Such transmission of financial friction is more salient among low-skill-intensity or non-state-owned firms, and greater labor mobility facilitates the transmission. Our findings highlight the distributional effect of financial friction in the economy: labor, especially the low-skilled ones, rather than capital, eventually bears the cost of financial friction.
