Welfare Distributional Change and the Measurement of Social Mobility
提出一种测量福利分配变化和社会流动性的新方法，利用价格依赖的个体和社会福利指标评估分配变动的方向和大小，并将流动性指数分解为组间和组内两部分，基于美国1947-1982年数据发现每年社会相对于1947年分布均呈向上流动。
A new approach to the measurement of welfare distributional change and social mobility is developed. The novel feature of this model is the use of price dependent measures of individual and social welfare in evaluating t he magnitude and direction of the movement in the distribution. In addition, the proposed indexes of mobility are decomposed into the sum of between-group and w ithin-group mobility. Each measure is implemented for the United States over the period 1947-1982. It is found that in each year society is upwardly mobile rela tive to the 1947 distribution. Copyright 1986 by MIT Press.
