Social Preferences and Agricultural Innovation: An Experimental Case Study from Ethiopia
通过在埃塞俄比亚进行实验，让农民用自己的钱减少他人的钱，发现基于绝对收入差异的不平等厌恶模型得到支持，且实验中测量的村庄层面金钱销毁行为与实际农业创新负相关，表明社会偏好对发展中国家农业创新至关重要。
We run an experiment in Ethiopia where farmers can use their own money to decrease the money of others (money burning). The data support the prediction from an inequality aversion model based on absolute income differences; but there is no support for an inequality aversion model based on comparison with mean payoff of others. Experimentally measured money burning on the village level is negatively correlated to real-life agricultural innovations. This result is robust even when data from another independent survey than the current research are used. This underscores the importance of social preferences in agricultural innovations in developing countries.
