In this work we characterize sudden increases in the land price of certain urban areas, a phenomenon causing gentrification, via an extended Schelling model. An initial price rise forces some of the disadvantaged inhabitants out of the area, creating vacancies which other groups find economically attractive. Intolerance issues forces further displacements, possibly giving rise to an avalanche. We consider how gradual changes in the economic environment affect the urban architecture through such avalanche processes, when agents may enter or leave the city freely. The avalanches are characterized by power-law histograms, as it is usually the case in self-organized critical phenomena.

扩展的谢林模型中的雪崩:对城市绅士化的解释

在这项工作中,我们通过扩展的谢林模型描述了某些城市地区土地价格突然上涨的现象,这种现象导致了绅士化。最初的价格上涨迫使一些处境不利的居民离开该地区,从而产生了其他群体在经济上具有吸引力的空缺。不容忍的问题迫使人们进一步流离失所,可能引起雪崩。我们考虑当代理商可以自由进出城市时,经济环境的逐渐变化如何通过雪崩过程影响城市建筑。雪崩的特征是幂律直方图,就像在自组织临界现象中通常那样。
