  • Religious Identity, Trust, and Prosociality

    In this paper we are interested in exploring the effects of religious social identity on trust, trustworthiness, and prosociality.

  • Soldier for Life, Student for Life: Personalized information and advising to improve postsecondary outcomes for separating Army servicemembers
    Last registered on January 26, 2022

    To increase service members’ awareness of well-matched, affordable colleges and universities and to support them to make informed decisions about whether and where to pursue postsecondary education, we designed and tested a large-scale experiment to provide service members separating from the U.S. Army with personalized and simplified information, reminders, and advising about their college and university options.

  • Does public flood aid crowd out private insurance II? (Firm survey)
    Last registered on January 26, 2022

    This is the second part of the project. The first part consisted in a household survey (registered as RCT ID: AEARCTR-0008603, on November 28, 2021). In the second part we carry out a similar survey but focus on firms. The firm surveys concentrate on a region (Upper Baveria, and in particular Oberland) which has experienced several flood events in recent years. Firms are recruited into the surveys via different channels: telephone calls, and invitations to participate in an online survey via local media, regional development agencies, and banks. The firm questionnaire is analogue to the household questionnaire (with small adjustments), but also includes extra sections on: a) flood experience (e.g. type and size of damage experienced); and b) physical adaptation measures. Further ...

  • Female entrepreneurship and husbands’ support: women’s investment in male-dominated pineapple production in Benin
    Last registered on January 26, 2022

    Pineapple is a dynamic value chain in Benin that attracts investments from various stakeholders. Small-scale farmers produce the majority of the crop and most of them are men. Although women play an important role in agriculture overall and often manage their own fields, few of them cultivate pineapple on their fields. They face several specific, gender-related constraints preventing their involvement in this productive activity, including liquidity constraints, problems with the planification of activities over the course of the 18 months production cycle, bookkeeping or competing demands on their time. Exploratory field work reveals that husbands’ support is a crucial determinant of women’s success in this activity. A husband may offer financial support or help in monitoring workers f...

  • Anti-Competitive Entry. Theory and Evidence from a Lab Experiment
    Last registered on January 26, 2022

    We model anti-competitive effects of entry within a search framework, and test the implications in an experiment in which the presence of entry (Y/N) and the share of uninformed buyers (15%;30%;60%) constitute the treatments. In our pilot study we observe prices that are broadly consistent with our theoretical findings. We added a treatment in January 2020. This treatment increased the size of a market from three to six sellers in the entry condition with 30% uninformed buyers. Data collection for the added treatment is planned to take place at the LEE lab (Econ department/University of Copenhagen week 10/2020). Apart from the market size, the added treatment is identical to the first six treatments. The aim is to test the proposition that the market size does not impact on price set...

  • Increasing the reach of promising dropout prevention programs: Examining the tradeoffs between scale and effectiveness
    Last registered on January 26, 2022

    The inability to consistently deliver promising education interventions at large scale is an important contributing cause to inequality in the U.S. The research team applies insights from price theory and field-based randomized controlled trials to examine the effect of implementing a promising academic skills development program at large scale before implementing at scale. The project is designed to provide evidence of direct scientific and policy value for attempts to scale-up a specific intervention, but also stimulate much more investigation of social policy scale-up challenges by refining these methods and demonstrating their feasibility and value. The research team examines the challenge of program scale-up for a promising intervention studied in Chicago at medium scale in the ...

  • Increasing the Efficacy & Diffusion of Covid-19 Messaging for Vaccination
    Last registered on January 26, 2022

    This study will distribute videos of health care professionals encouraging Covid-19 vaccination to a large sample of Facebook users, and will test the most effective ways to maximize diffusion of this vaccine-related content to increase vaccination rates. The study sample will be U.S. states where vaccination rates remained low in fall 2021. The experimental design is an RCT with 4 groups, randomized at the county level: 1) a control group which receives no intervention, 2) a treatment group in which Facebook users receive ads which include videos of health care professionals telling them to get vaccinated, 3) a treatment group in which Facebook users receive ads which include videos of health care professionals encouraging them to help their friends to get vaccinated, and 4) a treatmen...

  • Inequality with unequal opportunity
    Last registered on January 26, 2022

    We live in a society which values meritocracy, in which people are rewarded by their merit, rather than luck or other factors. Studies show that inequality is more acceptable to individuals when the source is considered as merit (Almas et al., 2020). We are interested in situations where the source of merit is unequal opportunity. Specifically, we investigate individuals’ preference for redistribution when the source of inequality involves unequal opportunity.

  • Social distance and consumer trust
    Last registered on January 25, 2022

    The present research aims to explore the role social distance plays in facilitating trust among customers of a major online retailer. In the context of online shopping, potential customers can not physically inspect the products they want to buy and they largely rely on the product reviews left by previous buyers for the first-hand insights on the product quality, suitability and decide whether the products are worth buying etc. However, product reviews, regardless how positive they are, will need to be trustworthy in the eyes of the potential buyers to have any effect given that 'fictitious product reviews' are now a wide-spread phenomenon in the competitive e-commerce business. In this setting, we explore whether a key social distance-reducing measure, that is showing the product revi...

  • The Power of Agency and Agricultural Transformation: Evidence from India
    Last registered on January 25, 2022

    Community-driven development (CDD) emphasizes a “bottom-up” approach focusing on community control over planning and implementation decisions to improve development outcomes. We propose to assess the value of community participation in choosing the location and implementation of local infrastructure projects by comparing a participatory “bottom-up” approach to the standard “top-down” planning and implementation where the community only plays a limited role. The context for the study is the construction of minor irrigation channels in the command area of small irrigation tanks in Telangana. The government has recently launched a program to rehabilitate the storage capacity of the tanks but has left the distribution of water from the tank to plots in the command area to the farmers. The r...
