Customary land conversion in sub-Saharan African cities
构建了一个城市模型，分析发展中国家城市中习惯农业用地向正式和非正式住宅用地的转换，发现产权风险和信息不对称可能导致城市发展不足，并以马里巴马科的数据验证了这些现象。
Abstract We propose an urban model to discuss the conversion of customary agricultural land to formal and informal residential land in developing country cities. Because customary land sales are insecure, migrant buyers face a risk of eviction, which affects land markets in non-trivial ways. Tenure risk and asymmetric information likely cause insufficient urban development. Empirical tests of the model for Bamako, Mali, confirm the existence of tenure insecurity and information asymmetry in the primary land market, but not in the secondary market, consistently with information revelation after initial sales by customary holders.
