Technology and Changes in Skill Structure: Evidence from Seven OECD Countries
比较美国与其他六个OECD国家工资账单和就业的技能结构变化，发现研发强度与技能升级显著相关，表明技能偏向型技术变革是国际现象，增加了对高技能工人的相对需求。
This paper compares the changing skill structure of wage bills and employment in the United States with six other OECD countries (Denmark, France, Germany, Japan, Sweden, and the United Kingdom). We investigate whether a directly observed measure of technical change (R&D intensity) is closely linked to the growth in the importance of more highly skilled workers which has occurred in all countries. Evidence of a significant association between skill upgrading and R&D intensity is uncovered in all seven countries. These results provide evidence that skill-biased technical change is an international phenomenon that has had a clear effect of increasing the relative demand for skilled workers.
