Exports and Wages: Rent Sharing, Workforce Composition, or Returns to Skills?
利用意大利1992年里拉贬值的自然实验，结合雇主-雇员匹配数据，研究发现出口企业既支付高于外部市场的工资溢价（租金分享效应），也雇佣技能价值因贬值而提升的工人（技能构成效应），且出口相关经验越多的工人溢价越大。
We use linked employer-employee data from Italy to explore the relationship between exports and wages. Exploiting the 1992 devaluation of the lira, we show that exporting firms both pay a wage premium above what their workers would earn in the outside labor market (the “rent-sharing” effect) and employ workers whose skills command a higher price after the devaluation (the “skill composition” effect). The latter only emerges once we allow for the value of workers’ skills to differ in the pre- and post-devaluation periods. We also document that the export wage premium is larger for workers with more export-related experience.
