    Abstract We conducted a fundraising experiment with an international development nonprofit organization in which a matching grant offered by the Bill and Melinda Gates Foundation raised more funds than one from an anonymous donor. The effect is strongest for solicitees who previously gave to other BMGF-supported, poverty charities. With supporting evidence from two other fundraising experiments as well as a survey experiment, we argue this is consistent with a quality signal mechanism. Alternative mechanisms are discussed, and not ruled out. The results help inform theories about charitable giving decision-making, and provide guidance to organizations and large donors on how to overcome information asymmetries hindering fundraising.

    Abstract Ethics in social science experimentation and data collection are often discussed but rarely articulated in writing as part of research outputs. Although papers typically reference human subjects research approvals from relevant institutional review boards, most recognize that such boards do not carry out comprehensive ethical assessments. We propose a structured ethics appendix to provide details on the following: policy equipoise, role of the researcher, potential harms to participants and nonparticipants, conflicts of interest, intellectual freedom, feedback to participants, and foreseeable misuse of research results. We discuss each of these and some of the norms and challenging situations of each. We believe that discussing such issues explicitly in appendices of papers, even if briefly, will serve two purposes: more complete communication of ethics can improve discussions of papers and can clarify and improve the norms themselves.

  7. Article ; Online: Evaluation of Combined Financial Incentives and Deposit Contract Intervention for Smoking Cessation: A Randomized Controlled Trial.

    Abstract Introduction: We evaluate whether a combination of financial incentives and deposit contracts improves cessation rates among low- to moderate-income smokers.
    Methods: We randomly assigned 311 smokers covered by Medicaid at 12 health clinics in Connecticut to usual care or one of the three treatment arms. Each treatment arm received financial incentives for two months and either (i) nothing further ("incentives only"), (ii) the option to start a deposit contract with incentive earnings after the incentives ended ("commitment"), or (iii) the option to precommit any earned incentives into a deposit contract starting after the incentives ended ("precommitment"). Smoking cessation was confirmed biochemically at two, six, and twelve months.
    Results: At two, six, and twelve months after baseline, our estimated treatment effects on cessation are positive but imprecise, with confidence intervals containing effect sizes estimated by prior studies of financial incentives alone and deposit contracts alone. At two months, the odds ratio for quitting was 1.4 in the incentive-only condition (95% CI: 0.5 to 3.5), 2.0 for incentives followed by commitment (95% CI: 0.6 to 6.1), and 1.9 for incentives and precommitment (95% CI: 0.7 to 5.3).
    Conclusions: A combined incentive and deposit contract program for Medicaid enrollees, with incentives offering up to $300 for smoking cessation and use of support services, produced a positive but imprecisely estimated effect on biochemically verified cessation relative to usual care and with no detectable difference in cessation rates between the different treatment arms.

    Abstract Objective: To evaluate the microfoundations of a personality-inspired public health campaign's influence on minors.
    Design: Multi-year randomized control trial.
    Setting: Economics professor's front porch in New Haven, CT.
    Participants: 1223 trick-or-treaters in New Haven over three years; on average, 8.5 years old and 53% male (among children whose gender was identifiable).
    Eligibility: Trick-or-treaters over the age of three that approached the house.
    Intervention: Random assignment to the Michelle Obama side of the porch or the Comparison side of the porch.
    Main outcome measure: Selection of fruit over candy.
    Methods: Difference-in-means estimates.
    Results: We estimate that viewing a photograph of Michelle Obama's face relative to control conditions caused children to be 19% more likely to choose fruit over candy.
    Conclusions: Michelle Obama's initiative to reduce childhood obesity has influenced children's dietary preferences. Whether this influence extends beyond Halloween trick-or-treating in New Haven, CT on the porch of an economics professor requires further research.
