Demand-Side Changes and the Relative Economic Progress of Black Men: 1940-90
利用1940-1990年人口普查数据，分析黑人男性相对白人男性经济进步停滞的原因，发现技能偏向型技术变革比产业结构变化影响更大，而女性和移民的竞争并非主因。
This article uses Census data from 1940 to 1990 to examine whether the hypotheses advanced for the absence of economic progress of black men relative to white men during the 1980s are consistent with the long-run trends. The findings indicate that skill-biased technological change explains more than changes in industrial composition both in the long run as well as in the 1980s. Moreover, increased competition from women and immigrants does not explain the recent slowed progress of black men; instead, the evidence suggests that middle-skilled white men may be an important source of increased competition.
