Land Tenure and Productivity: Farm-Level Evidence from Papua New Guinea
利用巴布亚新几内亚油棕项目的农场数据，发现土地产权形式显著影响生产率，其中产权更稳定的农场因规模经济和无需收入分享而生产率更高。
Does land tenure form affect farm-level productivity? The answer, from farm-level data for an oil palm project in Papua New Guinea, is in the affirmative. Analysis of farm-level output, controlling for all measured inputs, shows systematic differences in productivity across three land tenure types, namely, farms under customary purchase agreements, those under the land settlement scheme, and those under village-owned land schemes. The empirics suggest that the higher productivity is due to benefits from economies of scale and absence of income sharing enjoyed by farms with improved tenure security. <i></i>
