Spatial segregation and urban structure
研究了由竞争性土地价格调节的空间隔离模型，分析了两类群体因文化或种族差异导致的内群体互动多于外群体互动时，如何形成不同数量的城市区域结构，并探讨了群体规模与互动强度对均衡的影响。
Abstract In this paper, we develop a model of spatial segregation mediated by competitive land prices. Agents of two groups consume city land and benefit from social interactions. Because of cultural or ethnic differences, intragroup interactions are more frequent than intergroup ones. When group sizes differ, population groups sort into distinct neighborhoods. We characterize two‐ and three‐district urban structures. For high population ratios or strong intergroup interactions, only a three‐district city exists. In other cases, multiplicity of equilibria arises. Both groups generally rank these equilibria differently. However, when group sizes are similar, all individuals agree on which spatial equilibrium is best.
