Race and Poverty: A Forty-Year Record
利用1940至1980年五次人口普查数据，描述黑人贫困的长期趋势，分析劳动力市场变化及黑人家庭受冲击的情况，并探讨黑人男性逐渐脱离劳动力市场的问题。
Thirty years ago, Gary Becker in his now classic work, Economics of Discrimination, sparked renewed interest in an economic analysis of racial income disparities. The volumes of research papers that built on Becker's contribution over the last three decades added a great deal to what we know about the reasons for the wide income differences between the races. One reason was the emergence of several large scale micro data sets of which the 1960 census was the first. Today, analysis is based not only on the 1980 census file but also on several longitudinal data sets best represented by the Panel Study of Income Dynamics and the Parnes National Longitudinal Surveys. Ironically, it is the release of micro data files from two pre-Becker data sets that appears to offer the greatest potential for answering the important questions that remain. In this paper, we use these two data sets-the 1940 and 1950 census files-in combination with the three subsequent census files to describe long-run trends in black poverty. We begin by describing purely labor market developments, but supplement that depiction with a broader look at events that impacted on the black family. The paper concludes with an examination of the downside of black economic progress-the increasing disengagement of many black men from the labor market.
