College Tuition and Income Inequality
研究了美国收入不平等加剧如何解释1990年以来大学学费上涨，发现收入不平等可解释一半以上的平均净学费增长，并抑制了大学入学率。
This paper evaluates the role of rising income inequality in explaining observed growth in college tuition. We develop a competitive model of the college market, in which college quality depends on instructional expenditure and the average ability of admitted students. An innovative feature of our model is that it allows for a continuous distribution of college quality. We find that observed increases in US income inequality can explain more than half of the observed rise in average net tuition since 1990 and that rising income inequality has also depressed college attendance.
