Productivity Effects of Indigenous Land Tenure Systems in Sub‐Saharan Africa
利用加纳、肯尼亚和卢旺达的家庭调查数据，检验本土土地权利制度是否制约农业生产率，发现土地权利对投资、投入、信贷和生产率影响不显著，质疑当前大规模土地登记和确权项目的必要性。
Abstract This article uses household survey data from Ghana, Kenya, and Rwanda to test if the indigenous land rights systems in sub‐Saharan Africa are a constraint on agricultural productivity. Rights which farmers hold over individual parcels of land vary widely, and are in many cases surprisingly privatized. Yet with few exceptions, land rights are not found to be a significant factor in determining investments in land improvements, use of inputs, access to credit, or the productivity of land. These results cast doubt on the need for ambitious land registration and titling programs at this time.
