SQUATTING ON GOVERNMENT LAND
构建了一个经济理论模型，分析发展中国家棚户区侵占政府土地的现象，研究棚户区组织者如何控制侵占以避免被驱逐，以及正式居民因驱逐成本而容忍棚户区的权衡。
ABSTRACT This paper presents an economic theory of squatter settlements in developing countries. It adds to the existing literature by explicitly modeling squatting on government‐owned land and presents a unified framework for analysis of issues related to squatting, urban planning and policy. In the model, a squatter‐organizer optimally controls squatting so as to forestall eviction. The model highlights how the existence of an eviction cost leads to formal residents tolerating squatting, trading‐off “open space” to avoid paying taxes toward evicting squatters. The paper derives comparative‐static results under some functional form assumptions. The analysis is extended to examine the comparative‐static effects for the case where squatters freely migrate into the city. The framework for exploring a combined model of squatting on government and private land is also laid out. Finally, some policy analysis of squatter formalization is carried out.
