Abstract
We examine an intervention randomized at the village level in which female farmers invited to a single training session were randomly paired with farmers whom they did not know and encouraged to share new agricultural information throughout the growing season for a recently adopted cash crop. We show that the intervention signi ficantly increased the productivity of all farmers except of those who were already in the highest quintile of productivity, and that there were signifi cant spillovers in productivity to male farmers.

Publication As Good as the Company They Keep?(World Bank, Washington, DC, 2016-03)Extension services have a history of being relatively expensive and not always effective. At the same time, studies show that informal social networks can be very beneficial in helping increase productivity. In Uganda, the authors tested the value of informal social networks for women farmers by connecting the least-productive 30 percent to some of the most productive women farmers in their own villages. Results show significant gains in productivity indicating that the path to better outcomes is contained within their own community. Women learned the agricultural information at least as well in a network setting as in a more intensive, formal extension setting. On average, the social network intervention was less costly and more effectively targeted women and the least productive farmers than traditional extension services. By exploiting the power of social ties, social network interventions offer a lower-cost alternative to traditional agricultural training programs and can be particularly effective at improving the productivity of women. The results of the study featured in this brief are particularly relevant to policymakers in Sub-Saharan Africa, where productivity differentials still exist between males and females, and women are less frequently targeted for training.Publication Women's Empowerment, Sibling Rivalry, and Competitiveness(World Bank, Washington, DC, 2016-06)This study looks at how a community event—adolescent women's economic and social empowerment -- and a family factor -- sibling sex composition—interact in shaping gender differences in preferences for competition. To do so, a lab-in-the-field experiment is conducted using competitive games layered over the randomized rollout of a community program that empowered adolescent girls in Uganda. In contrast with the literature, the study finds no gender differences in competitiveness among adolescents, on average. It also finds no evidence of differences in competitiveness between girls in treatment and control communities, on average. However, in line with the literature, in control communities the study finds that boys surrounded by sisters are less competitive. Strikingly, this pattern is reversed in treatment communities, where boys surrounded by (empowered) sisters are more competitive.Publication Empowering Girls Triggers Their Brothers to Compete(World Bank, Washington, DC, 2016-10)This brief has key messages through an experiment in Uganda, we find that empowering adolescent girls triggers a surge in their brothers’ competitiveness.Understanding preferences for competition is important because competitiveness is a predictor of labor market outcomes. To examine gender differences in preference for competition, the World Bank’s Africa GenderInnovation Lab, in collaboration with researchers from the University of Maryland and ColumbiaUniversity, launched a lab-in-the-field experiment within a randomized control trial of BRAC’scommunity-based Empowerment and Livelihood for Adolescents (ELA) program in Uganda.The ELA program simultaneously provided vocational and life skills training for girls aged 14 to 20. An impact evaluation of ELA showed that it empowered girls along economic and social dimensions: the program increased girls’ participation in self employment, improved girls’ control over their bodies, and shifted deep rooted gender norms held by adolescent girls in communities that participated in the program. Four years after the implementation began, we used a lab-in-the-field experiment to compare communities that received ELA with those that did not. The aim of this experiment was to test whether girl’s empowerment would have a direct impact on girls’ or boys’ competitiveness. To measure preferences for competition, we implemented the experimental protocol of Niederle and Vesterlund (2007). More specifically, participants were asked to select a compensation scheme before performing a simple task, from which we identified their taste to compete. They either chose to be paid according to a competitive tournament scheme or a non competitive piece-rate scheme. The experiment was designed to control for a host of factors such as individual differences in ability, overconfidence, risk aversion, and altruism. Our findings highlight the impact of gender equality on gender differences in competitiveness: when boys are faced with more empowered sisters, they increase their competitiveness. This suggests that the benefits of adolescent girls’ empowerment programs may spill over beyond the participating girls themselves to their brothers. More work needs to be done to understand if the changed behavior in brothers will have persistent effects on girls in the future.Publication Competition or Cooperation?(Elsevier, 2018-03)This study explores the behavioral learning characteristics of smallholder female farmers in Uganda by quantifying the amount of information learned under different incentive schemes. The paper shows how competitive versus team incentives compare in motivating Ugandan farmers to learn and share information relevant to adopting a new agricultural technology. We find that tournament-based incentives provide greater outcomes in terms of total information learned than threshold-based team incentives. Furthermore the order of the incentive – whether the tournament precedes or follows the team incentive scheme – does not affect the volume of information learned. New information introduced between rounds was learned by more individuals under team incentives than under tournament incentives. The study provides direct practical policy recommendations for improving learning in the context of agriculture in Uganda.Publication Seeing is Believing? Evidence from an Extension Network Experiment(World Bank Group, Washington, DC, 2014-08)Extension services are a keystone of information diffusion in agriculture. This paper exploits a large randomized controlled trial to track diffusion of a new technique in the classic Training and Visit (T&V) extension model, relative to a more direct training model. In both control and treatment communities, contact farmers (CFs) serve as points-of-contacts between agents and other farmers. The intervention (Treatment) aims to address two pitfalls of the T&V model: i) infrequent extension agent visits, and ii) poor quality information. Treatment CFs receive a direct, centralized training. Control communities are exposed to the classic T&V model. Information diffusion was tracked through two nodes: from agents to CFs, and from CFs to others. Directly training CFs leads to large gains in information diffusion and adoption, and CFs learn by doing. Diffusion to others is limited: other males adopt the technique perceived as labor saving, with an effect size of 75 percent.
