Sorting and Long-Run Inequality
构建了一个包含教育、生育和婚姻匹配的代际动态模型，发现社会分层加剧会显著提高收入不平等，并揭示了四个关键机制。
Many social commentators have raised concerns over the possibility that increased sorting in society may lead to greater inequality. To investigate this, we construct a dynamic model of intergenerational education acquisition, fertility, and marital sorting and parameterize the steady state to match several basic empirical findings. We find that increased sorting will significantly increase income inequality. Four factors are important to our findings: a negative correlation between fertility and education, a decreasing marginal effect of parental education on children's years of education, wages that are sensitive to the relative supply of skilled workers, and borrowing constraints that affect educational attainment for some low-income households.
