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.

网络，奖励措施和技术采用：来自乌干达的一项随机实验的证据

我们使用来自乌干达的一项随机实验的数据来检验激励措施对采用耐旱玉米品种（DTMV）的决定以及产生影响的机制的影响。我们发现，社会认可（SR）激励对受过训练的农民的随机子集-传播农民（DF）-增加了从DF向其同居者的知识传播，并改变了DF与其邻居的信息网络。SR还增加了DF使用DTMV的可能性。但是，私人物质奖励的相应结果并不能最终确定。我们没有证据表明，知识传播的诱因增加了共同犯罪者采用DTMV的可能性。
