一项涉及咖啡修剪技术的独特自然实验被用来研究社会学习。修剪的产量效应需要两年时间才能显现，这一特征有助于识别社交学习，而相关的不可观察变量是社交学习和技术采用文献中关注的问题。使用的小组数据始于一项私人倡议，该倡议在秘鲁中部引入了系统的修剪，并包含了参与种植者的人口。结果显示，在种植者群体中，第一次修剪后两年，被采用的可能性至少增加了0.15。JEL分类：D83；Q12
A unique natural experiment involving a coffee pruning technology is used to study social learning. The yield effects of pruning take two years to appear, a characteristic that aids in identifying social learning apart from correlated unobservable variables that are a concern in the social learning and technology adoption literature. Panel data are employed that start with a private initiative which introduced systematic pruning in central Peru and that contain the population of participating growers. Results show a jump of at least 0.15 in the probability of adoption two years after the first pruning in a grower’s group. JEL classifications: D83; Q12
