Estimating the Impact of Trade and Offshoring on American Workers using the Current Population Surveys
将行业层面的贸易和离岸外包数据与1984-2002年个体工人数据关联，发现职业层面的全球化暴露对工资有显著影响，而行业层面影响不显著；工人因贸易转换职业导致实际工资损失12-17个百分点。
We link industry-level data on trade and offshoring with individual-level worker data from the Current Population Surveys from 1984 to 2002. We find that occupational exposure to globalization is associated with significant wage effects, while industry exposure has no significant impact. We present evidence that globalization has put downward pressure on worker wages through the reallocation of workers away from higher-wage manufacturing jobs into other sectors and other occupations. Using a panel of workers, we find that occupation switching due to trade led to real wage losses of 12 to 17 percentage points. © 2014 The President and Fellows of Harvard College and the Massachusetts Institute of Technology
