Employment Trends by Age in the United States
研究了美国不同年龄段男女就业率的分化趋势，发现教育结构、初婚年龄延迟和社会保障改革只能部分解释这一现象，大部分原因仍未知。
Abstract In the 1960s, 1970s, and 1980s, male employment rates were declining or flat at all ages, and female employment rates were rising or flat at all ages. But employment trends diverged more recently, with employment rising at older ages and falling at younger ages. We estimate labor supply models for men and women, allowing differences in behavior across age groups. The results indicate that changes in the educational composition of the population, the increase in age at first marriage, and Social Security reforms can account for a modest proportion of the divergence. However, much of the divergence remains unexplained.
