  • Impact evaluation of a performance-based financing project in the health sector in the Democratic Republic of Congo
    Last registered on February 23, 2024

    The study evaluates the impacts of a Performance-Based Financing (PBF) program introduced in selected districts in the Democratic Republic of Congo. The program was introduced in the context of the “Health Systems Strengthening for Better Maternal and Child Health Results” project that is financially supported by the World Bank, the Health Results Innovation Trust Fund and other partners such as USAID, GFF, and the Global Fund. The main goal of the project is to improve coverage and quality of maternal and child health services in targeted areas through providing contracted health facilities with performance payments according to defined quantity and quality indicators. The objectives of the impact evaluation are to: (a) identify the impact of the PBF approach on service utilization...

  • Impact Evaluation of Interventions to Expand Social Security in Jordan
    Last registered on February 23, 2024

    This study aims to experimentally test whether information frictions are a significant barrier to social security participation in Jordan.

  • The Impact of In-School Math Tutoring: Evidence from a Field Experiment in Middle School
    Last registered on February 23, 2024

    We evaluate the impact of an in-school math tutoring program in a charter middle school in Indiana. The population served by this school is low-income, with 97% receiving free or reduced-price lunch. Students are randomly assigned to receive either 1) No Tutoring, 2) Tutoring two times per week in a two-student group, or 3) Tutoring three times per week in a three-student group. The tutoring cost is the same ($40 per week per student) in both tutoring treatment arms. Our primary hypothesis is that tutoring of either type will improve end-of-year math assessment scores relative to the control condition.

  • General Equilibrium Effects of Cash Transfers in Kenya
    Last registered on February 23, 2024

    How redistribution affects the real economy is one of the central, unanswered questions in development economics. The effect of redistribution on the welfare of non-beneficiary households is theoretically ambiguous: there could be positive spillover effects through increased aggregate demand (a multiplier effect), or negative spillovers from price inflation or crowd-out by business expansion for non-beneficiaries. The NGO GiveDirectly provides large cash transfers to rural households in Kenya. We utilize an RCT to study the spillover effects of cash transfers on household welfare, prices, enterprise creation and local public finance and will make use of spatial variation in treatment density in order to estimate these effects.

  • A Nudge-based Phone Intervention to Promote Parent Engagement during School Closures in Mumbai, India"
    Last registered on February 22, 2024

    Research suggests that spending time with a child has a direct and causal effect on children’s cognitive test scores and socioemotional development, and it is the most productive input for cognitive and socioemotional skill development. For children from low socioeconomic backgrounds in particular, efforts to promote their holistic development during adversities hinge on parent-child engagement and parental investments in children. Using a Randomized Control Trial design, this research project will implement a phone-nudges program to spark changes in parent motivation and behavior.

  • Parents' preferences for their children's education and career paths
    Last registered on February 22, 2024

    We study the preferences of adults for their hypothetical child’s educational and career paths. For that purpose, we implement a discrete choice experiment among a representative survey of 6000 adults aged between 25 and 60 in Switzerland where we ask them in multiple choice situations which of two “careers” they would prefer for their child. These careers are defined by the highest educational attainment, wage, the hierarchical position in their job, and the risk that their job will be substituted within the next 10 years. We ask half of the survey sample about their preferences for their hypothetical daughter, and the other half about preferences for their hypothetical son. We investigate how career attributes affect the likelihood of a career being chosen, how these preferences for c...

  • Fintech Adoption by Retail Firms in an Emerging Market: Experimental Evidence of Tech, Marketing, and Financial Interventions
    Last registered on February 21, 2024

    Across developing economies, cash is the conduit for retail transactions. Policymakers, multinational product manufacturers and marketers of electronic payment systems are interested in understanding how to stimulate the growth of electronic payments in emerging markets. In this paper, we investigate what hinders the adoption of e-payment technology by traditional retailers, in particular, whether barriers to adoption are technological, informational or financial in nature. We do this through a rigorous field experiment, where we randomize 900 small retailers in Guadalajara, Mexico into four experimental groups: i) N = 225 firms receive an e-payment technology kit; ii) N = 225 firms receive the e-payment technology kit and informational materials to market e-payments to customers; iii) ...

  • Increasing Adoption and Varietal Turnover of Seed: The Role of Consumer and Producer Side Interventions
    Last registered on February 20, 2024

    To increase adoption of new agricultural technologies, both push (supply side) and pull (demand side) factors are important. As a push factor to increase adoption of a particular technology such as an improved seed variety, some level of initial subsidy is often offered. For instance, companies may offer free trial packs of new improved seed varieties; governments may offer subsidies to increase varietal turnover. However, it is also often argued that if something was subsidized (or even free), it may not be used for the intended purpose. In this paper, we first test the effectiveness of free trial packs by testing if farmers that receive a sample of a new improved seed variety are more likely to adopt it in the future than a control group of farmers who did not get a free sample. Furth...

  • Street Violence and Media Empowerment: Evidence from Guatemala
    Last registered on February 20, 2024

    Homicide is rampant in Latin America and the Caribbean. This project has a two-fold objective. First, it will provide evidence on the impact of an effort to protect at-risk youth in Guatemala through empowerment. This is implemented through a randomized individual-level intervention on the role of self-expression in shaping behavior among the youth living in areas festered with violence and lack of access to opportunities. For this purpose, the participation in a mass-media campaign will serve as main source of variation. Second, it aims to understand the role of media in the fight against gangs, by varying throughout the country the exposure to the mass-media among youth. To capture this, this project will exploit semi-random variation in the reception of radio and tv signals through t...

  • Inequality, Life Expectancy, and the Intragenerational Redistribution Puzzle
    Last registered on February 18, 2024

    In most OECD countries, pension reform policy has decreased the level of intragenerational redistribution over the last three decades, that is, redistribution among members of the same generation with high and low pension entitlements. This trend has occurred despite heterogeneity in life expectancy linked to socioeconomic status having a regressive impact on outcomes. This study contributes to solving this puzzle by means of a controlled laboratory experiment. We study the causal relationship between inequality of entitlements, mortality risk, and the size of redistribution in a stylized social security system.
