  • Communicating Program Eligibility: A Supplemental Security Income (SSI) Field Experiment
    Last registered on March 27, 2024

    Survey data from the Health and Retirement Study (HRS) suggest that less than 60 percent of individuals age 65 and over who are eligible for SSI receive SSI and administrative data suggest that take-up may be substantially lower than this. The economic literature has identified at least three main barriers to SSI take-up among individuals age 65 and over. First, individuals may not be aware that they are eligible for SSI (SSA 1976, Warlick 1982), which may be a particularly important barrier for individuals for whom being age 65 and over partly determines eligibility. Second, the expected magnitude of benefits affects take-up (McGarry 2000, McGarry and Schoeni 2015), with individuals with lower expectations about benefits less likely to participate in SSI. Third, potential SSI partic...

  • Equity and Efficiency - An experimental investigation
    Last registered on March 27, 2024

    We study choices about pie sharing in dyadic interaction with varying responder veto power. We consider a condition with fixed pie size (baseline) and two conditions with endogenously determined pie size (high and low efficiency loss conditions). We analyse baseline and efficiency loss conditions within subjects. We vary the order of conditions and the extent of the efficiency loss between subjects. We use the strategy vector method to elicit subjects' choices.

  • Migration narratives and attitudes towards immigration
    Last registered on March 27, 2024

    The research studies the effect of different narratives on perceptions and policy preferences towards migration among high school students in Rome. How do different narratives shape attitudes towards migrants? Are students more affected by narratives about in-group members or narratives about out-group members?

  • The power of giving advice
    Last registered on March 26, 2024

    Recent evidence has shown that giving advice can benefit the advisor (Eskreis-Winkler et al., 2018; 2019). There are several potential reasons underlying this result. For instance, when people give advice, they assess whether they are doing what they claim should be done and thus adjust their behavior accordingly (e.g., advising to eat healthy food to lose weight would be inconsistent with not eating healthy food if the goal is to lose weight). Also, being asked to provide advice may raise confidence (Eskreis-Winkler et al., 2018; Schaerer et a., 2018). The literature on mentoring has also acknowledged that mentors can substantially benefit from mentoring. Career mentoring has been associated with career success and improved job performance and job satisfaction, among others (Eby, ...

  • Offering scholarships to adult skilled workers
    Last registered on March 26, 2024

    Low-educated adults are underrepresented in adult education. At the same time, the current high-paced technological change shapes and stimulates demand for a labor force capable of constantly updating its skill set, which can result in a wedge between labor supply and demand if the supplied and demanded skill profiles grow apart. In a large-scale field experiment, we study if a financial incentive in the form of a scholarship increases enrollment in education among skilled adult workers.

  • Adoption and Use of Air Purifiers in Households in Dhaka
    Last registered on March 25, 2024

    Air pollution is one of the most serious threats to human well-being globally and especially in urban South Asia. As air pollution levels remain high in many cities, it is important to understand what defensive investments households can make in order to reduce the damage caused by air pollution. Indoor air purifiers are one of the most widely used and promising private defensive investments to reduce air pollution’s negative impacts. However, evidence of their effects is limited and usage remains low in low- and middle-income countries where air pollution is the highest. We propose to conduct an RCT on air purifiers in households in Dhaka, Bangladesh. The project has three main objectives. First, to understand how different framings of the air pollution problem lead to different levels...

  • From Convenience to Conscience: A Field Experiment on Influencing Local and Eco-Friendly Milk Purchases through Habit Formation
    Last registered on March 25, 2024

    Consumer interest in eco-friendly and local food sources is growing, leading to the adoption of glass bottles for taste preservation, recyclability, and reusability. However, the logistics of bottle return pose challenges for persistent demand. This study investigates the impact of monetary incentives on glass-bottled milk purchases and their potential to foster long-term habit changes. Partnering with a grocery co-op with more than 10,000 members, we implemented a randomized experiment at the household level where treated members received coupons at purchase, others upon bottle return, and a control group received no incentive. We hypothesize increased sales for incentivized groups with higher return rates when coupons are tied to returns and overall habit formation in treatment groups...

  • Empowering Communities for Maternal and Child Health: A Peer Group Counselling Experiment leveraging SHG Networks
    Last registered on March 25, 2024

    India faces profound challenges in reducing infant and maternal mortality rates and addressing malnutrition, particularly in rural and tribal areas. Despite various governmental initiatives like the National Rural Health Mission (NRHM) and Integrated Child Development Services (ICDS), poor health outcomes persist due to multiple factors including inadequate healthcare access, socio-economic deprivation, and lack of awareness. The study intends to enhance the effectiveness of existing health missions by integrating them with community-driven interventions. We designed a randomized field experiment that leverages women’s SHG networks to promote adherence to health and nutritional protocols among pregnant and lactating women. By engaging in group-to-peer counselling (facilitated by memb...

  • Beliefs, Norms and Health Behaviors
    Last registered on March 24, 2024

    The study will investigate how randomized information on sleep distribution and norms about sleep in the population may affect individuals beliefs about sleep duration and bedtime. The subjects will be divided in five main groups. A control group will not receive any information on others. Two treatment groups which will receive different information on sleep patterns or physical activity and norms regarding sleep and physical activity in different reference subpopulations. Two treatment groups will respectively receive informtation on the sleep and physical activity of someone from their same gender and in the same student year or (alternatively) another participant in the study with no information on their gender/student year.

  • Revitalizing Traditional Water Tanks for Climate Adaptation in India
    Last registered on March 24, 2024

    Irrigation allows farmers to adapt to heat stress or droughts. However, the threat of groundwater depletion and uneven access to irrigation make it an incomplete adaptation response. This project assesses how public goods, like water reservoirs that enhance widespread irrigation access through collecting and storing rainwater, can facilitate climate adaptation. We test the effectiveness of such tanks by studying the constraints they face from farmers' irrigation responses and other input markets like water and labor. In the Bundelkhand region of central India, traditional tanks were constructed centuries ago to store rainwater for irrigation during the next dry season. The tanks have accumulated silt over time reducing their capacity and ability to source water in the dry season. Ou...
