摘要

改良作物品种的使用可以提高农业生产力,提高农民的福利。本研究调查了改良玉米品种(IMV)的采用是否与埃塞俄比亚农村农民福利的增加有关。使用2009/10至2014/15年三波共收集1886个观测值的面板数据集进行分析。采用双障碍模型对采纳决策进行建模,采用固定效应工具变量方法估计采纳IMV的福利效应。我们的研究结果表明,IMV影响农民的福利。具体而言,我们发现采用IMV增加了家庭收入、资产所有权和玉米消费,同时也减少了收入贫困。贫困估计表明,分配给IMV的面积每增加10%,低于1.90美元贫困线的可能性就会降低4.79%。然而,采用IMV减少贫困的效果在不同的家庭中是不同的,拥有大量土地的家庭的效果最明显。我们的研究结果表明,促进获得IMV和耕地可以有效改善埃塞俄比亚农村农民的福利和减少贫困。

Improved maize adoption and impacts on farm household welfare: Evidence from rural Ethiopia

Improved maize adoption and impacts on farm household welfare: Evidence from rural Ethiopia

The use of improved crop varieties can increase agricultural productivity and enhance the welfare of farmers. This study examined whether the adoption of improved maize varieties (IMV) is associated with the increased welfare of farmers in rural Ethiopia. A panel data set with 1886 observations collected in three waves from 2009/10 to 2014/15 were used for the analysis. The adoption decision was modelled using a double-hurdle model, and the welfare effect of IMV adoption was estimated using a fixed-effects instrumental variable approach. Our findings reveal that IMV affects the welfare of farmers. Specifically, we found that IMV adoption increases households' income, asset ownership and maize consumption while also reducing income poverty. The poverty estimates indicate that a 10% increase in the area allocated to IMV was associated with a 4.79% reduction in the probability of being below the $1.90 poverty line. However, the poverty-reducing effect of IMV adoption was heterogeneous across households, with the most pronounced effect experienced by households with extensive landholdings. Our findings suggest that facilitating access to IMV and land under cultivation can effectively improve farmers' welfare and reduce poverty in rural Ethiopia.
