Expanding College Access in Taiwan, 1978–2014: Effects on Graduate Quality and Income Inequality
研究了台湾1990-2014年间通过专科升格为大学快速扩大高等教育规模，发现这并未降低收入不平等，反而因毕业生质量差异加剧了技能组内工资不平等。
Between 1990 and 2014, Taiwan increased the college share of its labor force from 7 to 32 percent by converting junior colleges to 4-year colleges. Such a rapid surge in skill supply should suppress college wages and lower wage income inequality. Instead, wage inequality rose 7 percent since 1978. We show that the surge of weaker college graduates made them poor substitutes for better-trained college graduates and led to an increase in wage inequality within skill groups. Rising wage inequality due to increased variation in the quality of young college graduates added another source of inequality to the Taiwan labor market. The Taiwan case shows that increasing college access alone will not lower inequality.
