Incentivizing and nudging farmers to spread information: Experimental evidence from Ethiopia
通过实验研究在埃塞俄比亚农民群体中，物质奖励和社会声望奖励如何激励小组长传播综合虫害管理知识，以及损失框架信息能否增强激励效果。
Abstract Information does not flow freely through social networks. We use an experiment to study knowledge diffusion about an innovation (integrated pest management, IPM) in farmer groups in Ethiopia. Group leaders are incentivized to share knowledge with members through the conditional provision of material or social prestige rewards. We combine incentives with loss‐framed messaging to leverage loss aversion. Incentives increase diffusion effort, and combining incentives with loss‐framed messaging increases effort further. However, the treatments failed to induce follower farmers to experiment with IPM. We also document that reclaiming material rewards is difficult after a long delay, attenuating the effectiveness of the loss frame.
