Can Falling Supply Explain the Rising Return to College for Younger Men? A Cohort-Based Analysis
发现美国年轻男性大学-高中学历工资差距翻倍，而年长男性几乎不变，英国和加拿大也有类似趋势。通过模型分析，认为这主要源于不同年龄组高学历工人相对供给的变化，而驱动因素是1950年代初出生队列开始的教育增速放缓。
Although the college-high school wage gap for younger U. S. men has doubled over the past 30 years, the gap for older men has remained nearly constant. In the United Kingdom and Canada the college-high school wage gap also increased for younger relative to older men. Using a model with imperfect substitution between similarly educated workers in different age groups, we argue that these shifts reflect changes in the relative supply of highly educated workers across age groups. The driving force behind these changes is the slowdown in the rate of growth of educational attainment that began with cohorts born in the early 1950s in all three countries.
