Abstract

We estimate the effects of increased exposure to agricultural technologies on farmers' adoption and economic well-being in Ghana, Mali, and Senegal using post-implementation data collected in 2019. The program, known as the West Africa Agricultural Productivity Program (WAAPP), aimed at improving agricultural productivity to enhance economic growth, food security and to reduce poverty and ran in two phases. We focus on the second phase of the program, which ran between 2012 and 2019. We use ex-ante matching at the village and household levels to select the estimation sample. We find that the treatment raised technology adoption by 0.32 percentage points and the adoption of improved seeds by 0.20 percentage points. The program also increased productivity and income of the treated households by 10% and 17% respectively, relative to the comparison households. There were no detectable effects on consumption and food security. We provide suggestive evidence indicating that the additional income may have been saved or invested. Taken together, these results suggest that multi-country agricultural programs can be effective at spurring economic transformation.

接触农业技术和采用:加纳、塞内加尔和马里的西非农业生产力项目

我们利用2019年收集的实施后数据，估计了加纳、马里和塞内加尔增加农业技术接触对农民采用农业技术和经济福祉的影响。该计划被称为西非农业生产力计划(WAAPP)，旨在提高农业生产力，促进经济增长、粮食安全和减少贫困，分两个阶段实施。我们的重点是该计划的第二阶段，即2012年至2019年。我们在村庄和家庭层面上使用事前匹配来选择估计样本。我们发现，该处理使技术采用率提高了0.32个百分点，改良种子采用率提高了0.20个百分点。与对照家庭相比，该项目还使接受治疗家庭的生产率和收入分别提高了10%和17%。对消费和粮食安全没有明显的影响。我们提供暗示的证据表明，额外的收入可能已被储蓄或投资。综上所述，这些结果表明多国农业项目可以有效地促进经济转型。

期刊介绍： Food Policy is a multidisciplinary journal publishing original research and novel evidence on issues in the formulation, implementation, and evaluation of policies for the food sector in developing, transition, and advanced economies. Our main focus is on the economic and social aspect of food policy, and we prioritize empirical studies informing international food policy debates. Provided that articles make a clear and explicit contribution to food policy debates of international interest, we consider papers from any of the social sciences. Papers from other disciplines (e.g., law) will be considered only if they provide a key policy contribution, and are written in a style which is accessible to a social science readership.
