Heterogeneity, Stratification, and Growth: Macroeconomic Implications of Community Structure and School Finance
研究社会经济分层和不同教育融资体系如何影响不平等与增长，发现将家庭分入同质社区短期降低异质性成本但长期混合能更快减少异质性，对教育财政改革有启示。
This paper examines how socioeconomic stratification and alternative systems of education finance affect inequality and growth. Agents interact through local public goods or externalities (school funding, neighborhood effects) and economywide linkages (complementary skills, knowledge spillovers). Sorting families into homogeneous communities often minimizes the costs of existing heterogeneity but mixing reduces heterogeneity faster. Integration, therefore, tends to slow down growth in the short run yet raise it in the long run. A move to state funding of education presents society with a similar intertemporal trade-off. Local and global complementarities play major roles in determining the efficient social and educational structures. Copyright 1996 by American Economic Association.
