Trade Exposure, Export Intensity, and Wage Volatility: Theory and Evidence
通过模型和行业数据，发现贸易开放度会放大国内生产率冲击对行业劳动力需求的影响，从而增加工资波动，但出口强度高的行业工资波动较小。
This paper addresses the link between trade exposure and wage volatility. First, it shows, in a simple model, that trade exposure magnifies the impact of domestic productivity shocks on industry-specific labor demand, particularly for the less export-intensive industries, and that, if labor is not perfectly mobile, this implies a rise in wage volatility. Then, it tests these predictions, using industry data. The empirical results confirm that wage volatility increases with an industry's degree of openness, and that it declines with an increase in the industry's export intensity. © 2005 President and Fellows of Harvard College and the Massachusetts Institute of Technology.
