Networks, incentives and technology adoption: evidence from a randomised experiment in Uganda
基于乌干达随机实验数据，研究社会认可激励对农民采纳抗旱玉米品种的影响，发现激励能促进知识传播和采纳，但未显著提高其他村民的采纳率。
Abstract We use data from a randomised experiment in Uganda to examine effects of incentives on the decision to adopt drought-tolerant maize varieties (DTMVs) and mechanisms through which effects occur. We find that social recognition (SR) incentives to a random subset of trained farmers – disseminating farmers (DFs) – increase knowledge transmission from DFs to their co-villagers and change information networks of both DFs and their neighbours. SR also increases DFs’ likelihood of adopting DTMVs. However, the corresponding results for private material rewards are not conclusively strong. We find no evidence that incentives for knowledge diffusion increase the likelihood of co-villagers adopting DTMVs.
