Farmer Field Days and Demonstrator Selection for Increasing Technology Adoption
通过实验发现，农民田间日（农民聚集学习新技术并观察其表现）使改良种子采纳率提高40%，对贫困农民效果更佳且成本有效；而通过村民会议选择早期采纳者则无显著效果。
Abstract Inadequate learning is an oft-cited friction impeding the adoption of improved agricultural technology in the developing world. We provide experimental evidence that farmer field days, an approach used throughout the world where farmers meet, learn about new technology, and observe its performance, alleviate learning frictions and increase adoption of an improved seed by 40%. Further analysis demonstrates that these field days are both cost-effective and have a greater impact on poorer farmers. In contrast, we find no evidence that selecting the first adopters of new technology in participatory village meetings has any effect on future adoption.
