过去发表的关于教育与农业生产率之间存在显著正相关的研究几乎都是使用亚洲的数据。除了一个例外，这些研究没有检查教育的积极影响是否只通过筛选能力来实现。利用肯尼亚和坦桑尼亚咖啡产区的家庭水平数据，这项研究发现，在其他变量不变的情况下，农业决策者具有计算能力和识字能力的家庭的农业产量增加了30%。对教育影响的这一估计明显高于将受教育年限作为自变量所作的估计。除了基本的算术和识字能力之外，提高认知技能对生产没有额外的影响。来自肯尼亚的证据（但不是来自坦桑尼亚的证据）表明，推理能力和家庭中至少有一个受过教育的人也会大大提高生产力。
Past published studies establishing a significant, positive link between education and agricultural productivity have used Asian data almost exclusively. With one exception, these studies have not checked to see if the positive impact of education comes about only by screening for ability. Using household level data from coffee regions of Kenya and Tanzania, this study finds that households in which the agricultural decision-maker is numerate and literate produce 30 percent more agricultural output, holding other variables constant. This estimate of the impact of education is markedly higher than those made using years of schooling as an independent variable. Increasing cognitive skills beyond basic numeracy and literacy has no additional impact on production. Evidence from Kenya (but not from Tanzania) suggests that reasoning ability and the presence of at least one educated person in the household also increase productivity substantially.
