Income portfolios in rural Ethiopia and Tanzania: Choices and constraints
分析了埃塞俄比亚和坦桑尼亚农村家庭的不同收入组合，发现其差异主要源于能力、地点和信贷获取，而非风险态度，对研究农村生计和贫困的学者有参考价值。
The article analyses the different income portfolios of households using survey data from rural Ethiopia and rural Tanzania. It suggests that the different portfolios held by households cannot be explained by their behaviour towards risk as is usually suggested. It is better explained by differences in ability, location, and in access to credit. A logit analysis of households with different income portfolios, controlling for the effects of location, suggests that entry into high‐return activities is determined by investment in particular skills or by access to capital.
