  • WILL-TO - A matched savings program to increase households' investments in children's education
    Last registered on March 18, 2024

    We evaluate the effectiveness of an education savings account program aimed at reducing low-income families' children's risk to drop out from secondary school in Italy. The program (WILL-TORINO) is implemented by a philanthropic organization in Torino, Northwestern Italy since 2020. The program targets 5th graders from low-income families and offers them and their families the opportunity to save small amounts of money (between 5 and 30 euros per month up to a maximum of 1,500 euros over a 6-year period) in a digital wallet. Household deposits are multiplied by four if the money is spent on proven educational expenses (e.g., computers/internet; culture, book purchases; various school expenses, language or computer courses, sports, transportation). In addition to the savings account, ben...

  • Two-sided Subsidies to Support Biofortified Crop Adoption in Guatemala
    Last registered on March 18, 2024

    As new climate-smart farming technologies become available, it will be necessary to learn which market mechanisms are effective at increasing access for rural farmers. If higher quality seeds are under-adopted due to information, behavioral, and/or financial frictions, it justifies subsidizing their distribution. This research considers two ways to subsidize seed dissemination - using demand-side subsidies to encourage farmers to try improved seeds and supply-side subsidies for agrodealers to promote and stock improved seeds. Subsidizing agrodealers is a potentially appealing and scalable policy option because they face market incentives. We study the effect of subsidizing both sides of the market to learn how subsidies affect uptake among inexperienced and experienced hybrid seed farmers.

  • Strategic Ignorance with Third-Party Information Provision
    Last registered on March 18, 2024

    A growing body of research, pioneered by Dana et al. (2007), has documented the prevalence of strategic ignorance in social decisions (e.g., Matthey and Regner 2011; Grossman 2014; van der Weele 2014; Feiler 2014; Exley 2016; Grossman and van der Weele 2017; Momsen and Ohndorf 2020, 2023; Serra-Garcia and Szech 2021): although people frequently incur a private cost to bring about some social benefit under conditions of full information, when the social benefit is uncertain, a surprisingly large number of people avoid easy opportunities to resolve this uncertainty and revert to selfish behavior. Although ignorance may stem from confusion or lack of interest, some individuals avoid information for strategic reasons, such as maintaining positive self - or social image (Nyborg 2011, Grossm...

  • The effect of technology-assisted behavioral interventions in type 2 diabetes
    Last registered on March 17, 2024

    The burden of diabetes is a growing global problem, not only for patients and families, but also for health insurance providers and the wider economy. Much of this is driven by lifestyle, such as what we eat and drink, smoking and how little we exercise. Health-related behaviour is difficult to shift. Measuring and tracking behaviour in the field is often a challenge. Wearable health-monitoring technology may offer innovative solutions for lifestyle modification, as well as the study of it. We want to understand how we can support diabetes patients form sustainable healthy-eating habits and increase glucose control. Our study is incorporating the behavioral changes that the COVID-19 pandemic may influence in this high risk population. It will be critical to understand the impact of the ...

  • When The Student Becomes the Master: Learning by Creating Math Tutoring Videos
    Last registered on March 16, 2024

    Teaching is anecdotally considered a good way to improve one’s own knowledge, but field evidence on learning by teaching is sparse. In this study, I partner with 22 middle and high schools in the midwestern United States to test the impact of creating math tutoring videos on students’ math skills. Stratified by teacher, 130 math classrooms are randomly assigned to either 1) Control, 2) Watchers, or 3) Creators conditions. In the “Watchers” classrooms, teachers assign a weekly PSAT math problem and students are given a link to a “help” video to watch. Students in the “Creators” classrooms are assigned the same problem, but are asked to create a video explaining the solution. The primary outcomes are students’ math class grades, as well as their score on a 15-question test of PSAT/ACT que...

  • Unawareness and Reverse Bayesianism
    Last registered on March 15, 2024

    This study experimentally investigates behavior under uncertainty when subjects experience growing awareness of states. The theoretical literature on evolution of preferences in response to growing awareness has suggested that subjective beliefs evolve according to reverse Bayesianism. Our experimental design allows us to disentangle behavior across two different dimensions. One dimension is whether or not behavior is consistent with reverse Bayesianism. The other dimension is whether preferences are consistent with subjective expected utility, the more general class of biseparable preferences, or with neither. The former dimension concerns between-awareness-levels behavior, while the latter dimension concerns within-awareness-level behavior. Our experimental design allows us to test co...

  • Non-willigness to lead and social preference
    Last registered on March 15, 2024

    Willingness to lead is not homogeneously distributed in the population. There is extensive research on the attributes of a good leader, and on how willingness to lead impacts leadership. But not a lot of research focuses on those who do not want to lead, the reasons why they do not put themselves forward, and if they would actually be better leaders than those who do not want to lead. I want to study the personality traits of those who do not want to lead, and if they would make different decisions for others than those who seek power. More precisely, I focus on distribution preference, i.e. the trade-off between efficiency (sum of individual payoffs), equality, and maximin (maximisation of the smallest payoff). Do individuals who do not want to lead take more equal or efficient decisi...

  • Methodology and decision-making for others in voting experiments
    Last registered on March 15, 2024

    There is extensive research on optimal election rules, rationality on going to the polls and strategic voting (see, e.g., Kittel, et al., 2014) but little is known about the impact of being elected in itself on politicians’ decisions. Democratically elected leaders should represent the electorate’s interest, but we know that other motivations, such as budget maximization or increasing the probability of being re-elected might crowd out the electorate's best interest. In this project we will study whether being elected rather than appointed leads politicians to act more in line with social preferences, giving more weight to the electorate’s preferences. Our Hypotheses are based on a larger social closeness to the group affected by the decision if the decision maker has been elected, ...

  • Culture
    Last registered on March 15, 2024

    This study is about understanding mechanisms underlying the long-term effects of culture.

  • Financial Aid Guarantees and University Selection
    Last registered on March 15, 2024

    We study the role of financial aid information in the post-secondary education decision; separating the effects of information alone and information with certainty. Our primary research question for the study asks: how does providing a minimum amount of guaranteed institutional financial aid effect the likelihood of students accepting offers of admission to a post-secondary institution.
