Lás microempresas, así como los proveedores de productos, enfrentan desventajas en comparación con las empresas más grandes respecto al abastecimiento de inventario porque, para reabastecerse, deben viajar con frecuencia y pagar costos más altos. Los investigadores evaluaron Agruppa, un servicio de tecnología que usa teléfonos móviles, el cual crea grupos virtuales de compradores para comprar a granel de forma más económica. La evaluación descubrió que la demanda inicial del servicio era alta, lo que ahorraba tiempo y gastos a los dueños de negocios, y aumentaba las ganancias de ciertos productos básicos. Sin embargo, dado que los dueños de negocios redujeron las ventas de otros productos, los ingresos y las ganancias cayeron en promedio y la demanda del servicio disminuyó con el tiempo. Agruppa finalmente cerró, lo que evidencia los desafíos de competir contra mercados centralizados.

Sending SMS messages with agricultural advice to smallholder farmers increased yields by 11.5% relative to a control group with no messages. These effects are concentrated among farmers who had no agronomy training and had little interaction with sugar cane company staff at baseline. A follow-up trial of the same intervention has, however, no significant impact on yields.

Numerosos gobiernos en países de ingresos medios y bajos, como Brasil y México, han adoptado programas de transferencias monetarias condicionadas (TMC) como una red de protección social, pero la mayoría de los beneficiarios de estas transferencias tienen poca o nula experiencia en el manejo de productos financieros formales. Para contribuir a cerrar la brecha respecto a la capacidad financiera de los beneficiarios del programa de transferencias condicionadas del Gobierno de Colombia, Fundación Capital diseñó LISTA, un programa basado en la noción de "liberar la educación financiera" del aula mediante el uso de aplicaciones diseñadas para usarse en tabletas. Los investigadores colaboraron con la Fundación Capital y el Gobierno de Colombia para realizar una evaluación aleatoria (RCT por sus siglas en inglés) de LISTA para estudiar su impacto sobre el conocimiento y el comportamiento financiero. LISTA tuvo impactos positivos significativos en el conocimiento financiero, las actitudes, las...

Objective: Despite the recognized importance of person-centered care, very little information exists on how person-centered maternity care (PCMC) impacts newborn health. Methods: Baseline and follow-up data were collected from women who delivered in government health facilities in Nairobi and Kiambu counties in Kenya between August 2016 and February 2017. The final analytic sample included 413 respondents who completed the baseline survey and at least one follow-up survey at 2, 6, 8, and/or 10 weeks. Data were analyzed using descriptive, bivariate, and multivariate statistics. Logistic regression was used to assess the relationship between PCMC scores and outcomes of interest. Results: In multivariate analyses, women with high PCMC scores were significantly less likely to report newborn complications than women with low PCMC scores (adjusted odds ratio [aOR] 0.39, 95% confidence interval [CI] 0.16–0.98). Women reporting high PCMC scores also had significantly higher odds of reporting a...

Recent research suggests giving cash directly to the poor can have a range of benefits for recipients in the first few years, including increased consumption, assets, and food security, but little evidence exists on the long-term effects of cash transfers, particularly as a way to spur entrepreneurship and increase earnings. To shed light on this question, researchers conducted a randomized evaluation in Uganda of a government self-employment program that provided cash grants of about $400 per person to groups of young adults to start a skilled trade. An IPA research team followed up after two, four, and nine years—providing some of the longest-term rigorous evidence on how start-up cash grants impact measures of poverty. Key Findings: »  Four years after grants were distributed, recipients were more likely to be practicing a skilled trade and earning 38 percent more than their peers who hadn’t received grants. The boost in earnings seemed to be driven by recipients’ work in skilled tr...

Enrollment in early childhood education has increased dramatically in Ghana, but the education sector now faces the challenge of ensuring young children learn and develop school readiness skills. This study evaluated the impacts of a scalable, in-service training and coaching program for kindergarten teachers, delivered with and without parental awareness meetings, on teaching practices and children’s learning and development. Key Findings: The in-service teacher training and coaching improved teachers’ use of the play-based kindergarten-specific pedagogy that is specified in Ghana’s national early childhood education curriculum. The program led to moderate impacts on teachers’ professional well-being, reducing teacher burnout for all teachers, and teacher turnover in the private sector. The teacher-training and coaching improved children’s school readiness, including their early literacy, early numeracy, and social-emotional skills in the first year. One year later, when children move...

Las fuerzas policiales urbanas tienden a enfocar sus esfuerzos en las áreas con tasas de crimen más altas. Sin embargo, incrementar la presencia estatal en los sitios más inseguros puede simplemente desplazar el crimen a otras áreas, dejando las tasas de crimen agregadas iguales a como estaban en un principio. En Bogotá, Colombia, un grupo de investigadores, en alianza con la Alcaldía de la ciudad, decidieron medir el impacto de tres estrategias sobre la reducción del crimen y su desplazamiento: focalizar la vigilancia policial, hacer mejoras al espacio público y una combinación de ambas estrategias. La evaluación encontró que estas estrategias reducen el crimen en las calles focalizadas en el estudio, pero solo cuando son implementadas al mismo tiempo. Mientras la mayoría de los crímenes, particularmente los delitos contra la propiedad parecen desplazarse a las calles aledañas. Hay evidencia que sugiere que los crímenes violentos, especialmente los homicidios y el abuso sexual, dismin...

Can greater control over earned income incentivize women to work and influence gender norms? In collaboration with Indian government partners, we provided rural women with individual bank accounts and randomly varied whether their wages from a public workfare program were directly deposited into these accounts or into the male household head’s account (the status quo). Women in a random subset of villages were also trained on account use. In the short run, relative to women just offered bank accounts, those who also received direct deposit and training increased their labor supply in the public and private sectors. In the long run, gender norms liberalized: women who received direct deposit and training became more accepting of female work, and their husbands perceived fewer social costs to having a wife who works. These effects were concentrated in households with otherwise lower levels of, and stronger norms against, female work. Women in these households also worked more in the long...

Lessons from randomized evaluations on managing and preventing crime, violence, and conflict.  What are the most promising strategies for reducing crime, violence, and conflict? The past decade has seen a dramatic expansion in the experimental literature designed to help answer this question. Moving beyond evaluations of individual programs, these studies seek to advance our understanding of what drives individuals and groups towards violence and conflict and the levers at our disposal for their reduction. This evidence review, prepared by staff at the Abdul Latif Jameel Poverty Action Lab (J-PAL) and Innovations for Poverty Action (IPA) for the Department for International Development (DFID), offers a broad review of the expansion of this literature and seeks to capture some of the emerging insights from across these studies. The review has been prepared as part of J-PAL and IPA’s Governance, Crime and Conflict Initiative (GCCI), a £12-million investment by DFID launched in 2017 to p...

Objectives: This study aimed to assess the accuracy of pregnant women’s perceptions of maternity facility quality and the association between perception accuracy and the quality of facility chosen for delivery. Design: A cohort study. Setting: Nairobi, Kenya. Participants: 180 women, surveyed during pregnancy and 2 to 4 weeks after delivery. Primary outcome measures: Women were surveyed during pregnancy regarding their perceptions of the quality of all facilities they were considering during delivery and then, after delivery, about their ultimate facility choice. Perceptions of quality were based on perceived ability to handle emergencies and complications. Delivery facilities were assigned a quality index score based on a direct assessment of performance of emergency ‘signal functions’, skilled provider availability, medical equipment and drug stocks. ‘Accurate perceptions’ was a binary variable equal to one if a woman’s ranking of facilities based on her quality perception equalled t...

Over the past two decades, sports programs have proliferated as a mode of engaging youth in development projects. Thousands of organizations, millions of participants, and hundreds of millions of dollars are invested in sports-based development programs each year. The underlying belief that sports promote socioemotional skills, improve psychological well-being, and foster traits that boost labor force productivity has provided motivation to expand funding and offerings of sport for development (SFD) programs. We partnered with an international NGO to randomly assign 1200 young adults to a sports and life skills development program. While we do not see evidence of improved psychosocial outcomes or resilience, we do find evidence that the program caused a 0.12 standard deviation increase in labor force participation. Secondary analysis suggests that the effects are strongest among those likely to be most disadvantaged in the labor market.

There is little evidence on how the large market for credit score improvement products affects consumers or credit market efficiency. A randomized encouragement design on a standard credit builder loan (CBL) identifies null average effects on whether consumers have a credit score and the score itself, with important heterogeneity: those with loans outstanding at baseline fare worse, those without fare better. Selection, treatment effect, and prediction models indicate the CBL reveals valuable information to markets, inducing positive selection and making credit histories more precise, while keeping credit scores’ predictive power intact. With modest targeting changes, CBLs could work as intended.

Accumulating evidence suggests that pay-for-performance (P4P) contracts can elicit greater effort from incumbent civil servants, but less is known about how these contracts affect the composition of the public sector workforce. We provide the first experimental evidence of the impact of P4P on both the compositional and effort margins. In partnership with the Government of Rwanda, we implemented a ‘pay-for-percentile’ scheme (Barlevy and Neal 2012) in a novel two-tier experimental design. In the first tier, we randomly assigned teacher labor markets to either P4P or equivalent fixed-wage contracts. In the second tier, we implemented a ‘surprise’, school-level re-randomization, allowing us to separately identify the compositional effects of advertised P4P contracts and the effort effects of experienced P4P contracts. Our pre-analysis plan sets out a theoretical framework that helps to define a set of hypotheses, and conducts simulations on blinded data to develop high-powered tests. We...

Background Globally, there has been increasing attention to women’s experiences of care and calls for a person-centered care approach. At the heart of this approach is the patient-provider relationship. It is necessary to examine the extent to which providers and women agree on the care that is provided and received. Studies have found that incongruence between women’s and providers’ perceptions may negatively impact women’s compliance, satisfaction, and future use of health facilities. However, there are no studies that examine patient and provider perspectives on person-centered care. Methods To fill this gap in the literature, we use cross-sectional data of 531 women and 33 providers in seven government health facilities in Kenya to assess concordance and discordance in person-centered care measures. Additionally, we analyze 41 in-depth interviews with providers from three of these facilities to examine why differences in reporting may occur. Descriptive statistical methods were use...
