论文摘要
本文将种族和住宅隔离的原始Schelling（1969，1971a，b，2006）概括为由于社会联系而引起的可变外部性的背景。在个人的效用函数是启发式函数的凸组合，距离朋友的距离以及移动成本的凸组合，原始模型的预测被减弱：隔离平衡不是独特的解决方案。虽然距离的成本具有单调的ProStatus-Quo效应，相当于迁移和重力模型的模型，但如果在独立过程之后形成朋友和邻居，那么朋友在太空中的位置会产生外部配置，如果与朋友的距离很小，并且每个代理的程度很高，则可以增强初始配置。对隔离平衡的影响至关重要地取决于网络外部性的作用。
This paper generalizes the original Schelling (1969, 1971a,b, 2006) model of racial and residential segregation to a context of variable externalities due to social linkages. In a setting in which individuals' utility function is a convex combination of a heuristic function a la Schelling, of the distance to friends, and of the cost of moving, the prediction of the original model gets attenuated: the segregation equilibria are not the unique solutions. While the cost of distance has a monotonic pro-status-quo effect, equivalent to that of models of migration and gravity models, if friends and neighbours are formed following independent processes the location of friends in space generates an externality that reinforces the initial configuration if the distance to friends is minimal, and if the degree of each agent is high. The effect on segregation equilibria crucially depends on the role played by network externalities.
