Title: Trade liberalization, labor market power, and misallocation across firms: Evidence from China's WTO accession

贸易自由化、劳动力市场势力与企业间的资源错配：来自中国加入WTO的证据

摘要：This paper studies the impact of trade liberalization on the heterogeneity of labor market power among manufacturing firms, which is a potential source of misallocation. The model shows that heterogeneity of labor market power distorts the allocation of the factors of production, and the variance in the natural log of the markdown serves as a sufficient statistic to infer its negative impact on overall production efficiency. Using China's accession to the World Trade Organization (WTO) as a natural experiment, the empirical results suggest that lower input tariffs decrease the variance in the natural log of the markdown, which reflects the improvement in misallocation. In contrast, reductions in output tariffs have no significant effects.

本文研究了贸易自由化对制造业企业间劳动力市场势力异质性的影响，这是导致资源错配的一个潜在来源。模型显示，劳动力市场势力的异质性扭曲了生产要素的配置，而折扣自然对数的方差作为推断其对整体生产效率负面影响的充分统计量。以中国加入世界贸易组织（WTO）作为自然实验，实证结果表明，较低的输入关税降低了折扣自然对数的方差，这反映了错配的改善。相比之下，输出关税的降低没有显著影响。
