Wage trickle down versus rent trickle down: How does an increase in college graduates affect wages and rents?
研究发现，城市大学毕业生比例上升时，高技能工人工资增长超过租金上涨而获益，低技能工人工资增长却被租金上涨完全抵消，且住房财富差距扩大，尤其在住房供给弹性低的城市。
Abstract We extend the Rosen–Roback spatial equilibrium model to show that increasing city‐level college share affects welfare distribution by changing both wages and housing costs heterogeneously across individuals with different education levels. Using the Panel Study of Income Dynamics (PSID) from 1980 to 2013, we confirm that high‐skilled workers gain greater benefits from living in cities with a rising college share, as the increase in their wage premiums outweighs their rent growth. However, the increased earnings of the unskilled are completely offset by higher housing rents. In response to the college graduate influx, housing wealth also increases significantly more for college graduates, further widening the welfare gap. The increased welfare gap is greater in cities where housing supply is inelastic.
