We provide a competitive equilibrium theory of urban segregation in a linear city. Households demand consumption and housing along the city and are exposed to neighborhood externalities. We show that equilibria that are robust to small coalitional deviations are segregated. Our results explain urban segregation in a standard neoclassical framework and shed new light on the difficulties faced by authorities to integrate cities.

城市隔离的空间理论

我们提供了线性城市中城市隔离的竞争均衡理论。家庭需要城市沿线的消费和住房，并面临邻里外部性的影响。我们证明，对小的联盟偏差具有鲁棒性的均衡是分离的。我们的研究结果解释了标准新古典主义框架中的城市隔离，并为当局整合城市所面临的困难提供了新的线索。
