本文分析了1994-2004年埃塞俄比亚化肥推广项目的效率。采用化肥为确保和稳定偏远脆弱地区的粮食生产提供了一个合适的战略。推广服务方案在支持化肥应用方面有着悠久的历史。然而，他们的效率受到质疑。在我们的分析中，我们集中在肥料扩散有相当大时间滞后的七个村庄。采用匹配技术避免了在治疗（接受推广服务的家庭）和控制家庭的比较中样本选择的偏差。除了共同的因素外，由种族和宗教所代表的文化措施旨在控制推广人员和农民之间的潜在紧张关系，这种紧张关系阻碍了方案的效率。我们发现推广服务对第一次采用化肥有相当大的影响。对七个村庄中的五个村庄的影响是一致的。

英文摘要：
The paper analyses the efficiency of extension programs in the adoption of chemical fertilisers in Ethiopia between 1994 and 2004. Fertiliser adoption provides a suitable strategy to ensure and stabilize food production in remote vulnerable areas. Extension services programs have a long history in supporting the application of fertiliser. How-ever, their efficiency is questioned. In our analysis, we focus on seven villages with a considerable time lag in fertiliser diffusion. Using matching techniques avoids sample selection bias in the comparison of treated (households received extension service) and controlled households. Additionally to common factors, measures of culture, proxied by ethnicity and religion, aim to control for potential tensions between extension agents and peasants that hamper the efficiency of the program. We find a considerable impact of extension service on the first fertiliser adoption. The impact is consistent for five of seven villages.
