Off-farm labour allocation decisions in small-scale rural households in Zimbabwe
使用双障碍模型分析津巴布韦Shamva地区小农户家庭成员的非农劳动参与和劳动时间决策，发现性别、教育、资产等因素对参与和工时的影响不同。
The double hurdle model is used to analyse the off-farm labour decisions of small-scale agricultural household members in the Shamva District of Zimbabwe. The approach permits the joint modelling of the decision to participate in the labour market and the decision regarding the amount of time allocated to work. Results indicate that a number of variables (notably, gender, education and assets) indeed have effects which are qualitatively and quantitatively different in terms of participation and hours worked. Overall, the empirical analysis confirms the importance of individual characteristics (such as gender and education) and household/farm characteristics (e.g. land area accessible to the household, productive assets, remittances and the agricultural terms of trade) in influencing the labour market decisions of rural household members.
