Computing Inequality: Have Computers Changed the Labor Market?
研究计算机化（技能偏向型技术进步）对1940-1996年美国教育工资差距扩大的影响，发现对大学毕业生相对需求持续增长，且技能升级在计算机密集型行业更快。
This paper examines the effect of skill-biased technological change as measured by computerization on the recent widening of U. S. educational wage differentials. An analysis of aggregate changes in the relative supplies and wages of workers by education from 1940 to 1996 indicates strong and persistent growth in relative demand favoring college graduates. Rapid skill upgrading within detailed industries accounts for most of the growth in the relative demand for college workers, particularly since 1970. Analyses of four data sets indicate that the rate of skill upgrading has been greater in more computer-intensive industries.
