Livestock and Private Tree Holdings in Rural Ethiopia: The Effects of Collective Action Institutions, Tenure Security and Market Access
利用2000-2007年家庭面板数据，研究发现集体行动和土地权属保障促进牲畜和非桉树树木的积累，而市场准入则促进桉树持有，对理解非洲农村资产积累有参考价值。
This article uses househld panel data spanning the period 2000–2007 to test hypotheses from the literature that secure land tenure, market access and collective action promote accumulation of private capital assets in rural highland Ethiopia. The three natural capital assets analysed in the article, livestock, eucalyptus trees and non-eucalyptus trees on households’ farm plots, make up virtually 100 per cent of privately held disposable assets. Incomes and capital stocks are extremely low and constant and tree assets are at least as important as livestock. We find that collective action and secure land tenure have strong positive effects on accumulation of livestock and other trees, but not eucalyptus. We also find evidence that market access promotes eucalyptus holdings and that other types of wealth tend to be positively associated with private natural capital stocks.
