Changes in Labor Force Composition and Male Earnings: A Production Approach
估计总量生产模型，研究劳动力构成变化对大学毕业生相对收入下降以及年轻工人相对收入下降的影响，发现劳动力构成变化能解释大部分收入变化，尤其是年轻男性大学毕业生数量快速增加的影响。
Models of aggregate production are estimated and used to investigate the effects of changes in labor force composition on the recently observed decline in the earnings of college graduates relative to other workers and on the fall in the earnings of younger workers relative to older workers. Changes in labor force composition explain substantial proportions of these observed earnings changes. The most important compositional change appears to have been the rapid increase in the number of young male college graduates. Projections outside the sample are consistent with depressed earnings throughout the lifetimes of the large baby-boom cohorts, especially among college graduates, but do not suggest that depressed college graduate earnings are a permanent phenomenon for all birth cohorts.
