  • Anti-Stigma Interventions to Encourage HIV Testing in Vulnerable Households in Mozambique
    Last registered on October 18, 2019

    This study aims to test whether providing information that intends to relieve individuals concerns about HIV-related social stigma improves HIV testing rates in vulnerable households in Mozambique. Based on a local social opinion survey before this study, the treatment group will receive individually-tailored information indicating supportive social opinions about HIV in their neighborhood. The primary outcome of interest is the usage of HIV-testing coupons, which will be distributed to all study participants and redeemable upon taking an HIV test in the local clinic.

    Online experiment to study how signaling motives for prosocial behavior interact with incentives for bunching

  • Matching or Cash Grants for Entrepreneurs: What is more Effective? Experimental Evidence from the Bagré Growth Pole Project in Burkina Faso.
    Last registered on October 18, 2019

    Burkina Faso’s population and especially the workforce is rapidly growing. Although unemployment is low (0.6 percent), about 70 percent of Burkinabè work in low-productive agricultural activities. A key challenge for policymakers is to find effective interventions that create productive jobs for the youth. This research project seeks to provide rigorous evidence on the impacts of two private sector-based interventions – matching and cash grants – on the performance and employment by firms in agricultural value chains. These interventions provide alternative mechanisms of support to micro, small and medium-sized enterprises (MSMEs) located in a special agri-business development zone in rural Burkina Faso. The study makes use of a randomized controlled trial (RCT). It is embedded into the...

  • The Causal Effect of Air Pollution on Anti-social Behaviour
    Last registered on October 18, 2019

    The aim of this study is to provide causal evidence on the link between pollution and antisocial behaviour. We plan to estimate the causal impact of air pollution on economic decision-making by exploiting exogenous variation in local air pollution in Beijing, China. The primary outcomes of interest are experimental measures of antisocial behaviour obtained using incentivized experimental games including the 'Take Game' (as a measure for crime in the lab), 'Joy of Destruction Game' (as a measure of anti-social behaviour) and a third-party punishment game (as a measure of enforcement of pro-social behaviour). We also collect a range of secondary outcomes, which constitute potential mechanisms for effects on the primary outcomes, including tests of cognitive capacity, revealed measures for...

  • Social Comparisons and Groundwater Extraction
    Last registered on October 18, 2019

    A large literature examines the effect of social comparisons in nudging individuals toward pro-social behavior. This study builds on this literature by analyzing the salience of social comparisons in determining resource use behavior in the novel context of groundwater use among agricultural producers. We utilize a randomized control trail to measure how the provision of information comparing an individual’s past groundwater pumping to that of their neighbors affects the individual’s future groundwater use.

  • Evaluating the Impact of Social and Financial Education on Upper Primary School Children in Himachal Pradesh, India - A Cluster Randomized Trial
    Last registered on October 18, 2019

    This paper presents a research protocol for a cluster randomized trial to study the impact of an innovative social and financial skill teaching program for upper primary children aged between 9-16 years, across two districts in Himachal Pradesh, India. A total of 74 schools were randomly allocated to the treatment or control group. Outcomes to be measured are level of self-efficacy, knowledge of basic financial concepts, ability to solve simple financial tasks, level of patience and risk preference, amount of money saved, level of numerical ability, and knowledge on civil rights and responsibilities. The evaluation is funded by Echidna Giving.

  • Delivering parenting interventions through health services in the Caribbean
    Last registered on October 18, 2019

    Integrating early childhood interventions with health and nutrition services has been recommended, however there is limited information on interventions that are effective and feasible for delivery through health services. In this trial we developed and evaluated a parenting program that could be integrated into primary health center visits. The intervention used group delivery at five routine visits from age 3-18 months, and comprised: short films of child development messages, shown in the waiting area; discussion and demonstration led by community health workers; and mothers’ practice of activities. Nurses gave out and reviewed message cards with mothers, together with a few play materials. A cluster randomized trial was conducted in the Caribbean (Jamaica, Antigua and St Lucia) in 2...

  • Nudging Firms to Increase Labor Inclusion
    Last registered on October 18, 2019

    In early 2018, Chile enacted a new regulation on the labor inclusion of people with disabilities, in the form of law 21,015. This law dictates that all public firms and institutions with more than 100 employees must reserve 1% of its positions for people with disabilities. Taking this into account, the Chilean scenario presents a far more promising context for firm compliance than other countries in the region where quotas are set at 4% or 5%. This paper examines whether firm compliance to the newly established quota can be nudged through messages embodied with behavioral insights. The experiment includes designing the letters, randomizing the firms, sending the letters and monitoring the implementation.

  • On Rating Scales in Subjective Performance Evaluations - Performance Effects of Kindness
    Last registered on October 18, 2019

    To incentivize employee performance, many companies employ performance appraisals that are tied to compensation. In such ratings, employees are typically evaluated on a specific predetermined scale. It is often observed that the lowest rating categories are unused resulting in compressed appraisals. So far, research on subjective evaluations often associated this behavior with rating bias. In this project however, we study the question whether compressed appraisals may be designed by companies intentionally adding unused lower categories in order to frame rating scales to avoid negatively reciprocal reactions of employees.
