Productivity Gains from Trade: Bunching Estimates from Trading Rights in China
通过分析中国企业应对贸易监管政策时的操纵行为，利用聚集估计发现参与国际贸易能提升企业生产率，且这种提升随时间增强，年轻企业和非国有企业获益更多，工人通过工资增长分享收益。
Abstract This paper identifies productivity gains from trade by studying the manipulation behavior of firms in response to regulatory policies on international trade in China. Bunching estimates show that participation in international trade increases firm productivity. The productivity gains increase over time, indicating dynamic learning from trading. Further exploration shows no effects on R&D investment, product rationalization, and markup. Young firms and nonstate-owned firms (non-SOEs) gain more from participating in trade. Workers share productivity gains through increased wages but not from increased employment.
