  • Defaults and Sharing Personal Information about the COVID-19 infections
    Last registered on March 28, 2024

    This study experimentally examines how default settings influence individuals’ decision to share their personal information, such as the COVID-19 infection experiences and behavioral history, in the wake of a future pandemic. During the COVID-19 pandemic, scientific technologies for contact tracing were introduced to accurately identify signs of the spread of infection and take immediate actions. However, in many countries, the rate at which people accepted the technology and shared information about their infections and social contacts was low. For example, individuals were required to download a contact tracing application in order to accept the technology, and such the procedure possibly determined the rate. On the other hand, it has been discussed that, in order to increase the rate...

  • Ghana Financial Incentives Trial Wave II: Spillover and Tuberculosis Screening
    Last registered on March 28, 2024

    The Wave I Ghana Financial Incentive trial confirmed that financial incentives have a positive effect on COVID-19 vaccine intentions, reported vaccination status and verified vaccination status. Wave II provides an opportunity to understand whether this financial incentive effect generalizes to other types of health behavior: Does a similar financial incentive design with tuberculosis screening produce similar positive results? The Wave I trial was designed to identify any spillover effects across treatment arms or on untreated individuals within treated communities. We found no evidence of negative spillover effects of cash incentives on individuals who received no cash compensations. An unanswered question is whether the financial incentives affect within-subject behavior. Wave I...

  • Violence against women: The witness dilemma
    Last registered on March 28, 2024

    In Spain, the reform of the Violence Against Women (VAW) law (Royal Decree-Law 9/2018) made it possible to report gender violence without going to the police or court. The advantage of this kind of “soft reporting” is that victims or witnesses can report to social services and thereby gain access to legal, economic and psychological support without having to identify or denounce the aggressor. It is expected that the availability of soft reporting will help to reduce costs and overcome barriers to reporting. Results of a previous experiment (AEARCTR-0010397) showed that potential witnesses are more willing to intervene using the soft reporting option compared with the hard reporting option. In this study, we want to disentangle the main mechanisms that make people more inclined to in...

  • Violence against women: Witness intervention under different reporting options and violence scenarios.
    Last registered on March 28, 2024

    In Spain, the reform of the Violence Against Women (VAW) law (Royal Decree-Law 9/2018) has introduced the possibitlity that individuals report instances of VAW without the necessity of involving the police or the court. This approach, termed "soft reporting," provides victims or witnesses with the option to report to social services. By doing so, they can access legal, economic, and psychological support without the obligation to disclose the identity of the aggressor. This approach is anticipated to streamline the reporting process, reducing costs, and eliminating barriers that may hinder reporting. The findings of a prior experiment (AEARCTR-0010397) indicated a greater willingness among witnesses to intervene when presented with the soft reporting option as opposed to the hard rep...

  • 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...
