  • Mutual agreement and procedural fairness
    Last registered on June 24, 2026

    Economists have discussed different perspectives on ”procedural fairness”. Examples of ”fair” procedures include unbiased random processes (Machina’s mom) and symmetric games [Sugden and Wang, 2020]. We want to add the idea that a procedure (random process or game) will be considered more ”fair”, and the outcomes it generates more ”acceptable”, if the participants have unanimously agreed to it. That is, even a biased lottery or an asymmetric game may be regarded as ”fair” if it was agreed to even by the disadvantaged party.

  • Technology and Local Tax Capacity in Ghana
    Last registered on June 24, 2026

    This project evaluates the potential for technology to alleviate constraints on local tax capacity. Working in collaboration with a local government and a local private firm in Ghana, the project randomizes the availability of technology for tax collectors in the field. Collectors face several constraints to achieve their objectives of delivering bills and collecting tax payments which technology may partly remove. In addition, we study whether the presence of technology impacts property owners' belief about capacity of the state and engagement with local officials.

  • Monetary Transfers to Disadvantaged Youth in France (RCA)
    Last registered on June 24, 2026

    Many young people enrolled in the French aid agencies for employment seeking seem to have difficulties in reaching sustainable social and professional integration despite the availability of services. Among the reasons given for this lack of sustainability for the efforts made towards social integration of young people, two of them return frequently. The first is the existence of financial constraints faced by youth: reflecting the lack of financial autonomy of youth, these constraints can thus lead to undertake investment choices in their professional and education career that are very different from those they would have done in the absence of such constraints. The second is the lack of adherence to the programs these agencies propose. Joining a program for professional and so...

  • Empowering Parents in the Digital Age: Does Good-Practices Information Shift Parenting Behaviour? — Follow-Up Replication Study
    Last registered on June 24, 2026

    This pre-analysis plan (PAP) describes a replication and extension of our earlier survey-experiment in which UK parents with children aged 10–15 were exposed, via a four-week text message-delivered programme, to "good practices" information on how to manage their children's social-media use. That experiment yielded preliminary evidence that the good-practices arm shifted parents' stated willingness to change their behaviour, especially regarding parent-child communication. The present study re-tests that finding in a new, larger, independently recruited sample using a shorter (condensed) version of the same informational video, delivered via Qualtrics/Prolific. Two surveys are administered: a baseline survey embedding the randomised video exposure and immediate post-exposure outcomes, a...

  • From Degrees to Skills: How Job Requirements Shape Applicant Composition and Fit
    Last registered on June 23, 2026

    This paper examines how skill-based hiring practices influence the composition of the applicant pool, focusing on candidates’ educational backgrounds, skill profiles, race, and gender. Evidence shows that degree requirements often exclude qualified candidates and reinforce inequality, prompting many employers to adopt skill-based practices such as removing degree requirements to signal that skills, rather than credentials, will drive hiring decisions. Yet little is known about how such requirements affect job seekers’ application behavior. To address this gap, I partnered with a firm hiring for entry-level positions in software engineering and marketing and randomized the educational qualifications stated in job postings across three conditions: (1) a bachelor’s degree explicitly requir...

  • Plan Recommendations in the Medicare Market: A Survey of Medicare Intermediaries
    Last registered on June 23, 2026

    This study seeks to understand how intermediaries in the Medicare market advise clients and make Medicare plan recommendations. We also evaluate how intermediaries respond to different consumer cues and measure broker beliefs about how much consumers value different Medicare plan attributes. The results inform a broader study of how intermediaries shape Medicare plan choice.

  • Administrative Complexity, Take-Up, and Targeting of Social Benefits
    Last registered on June 23, 2026

    This study examines how administrative requirements affect intended take-up and targeting of means-tested social benefits. We implement a vignette-based factorial experiment in the IAB Online Panel for Labour Market Research (IAB-OPAL). Respondents evaluate hypothetical minimum-income benefits that vary randomly in benefit amount and administrative requirements, including application obligations, form length, documentation requirements, documentation mode, language assistance, and application channel/travel time. The main outcome is whether respondents would apply for the benefit. We estimate average marginal component effects of administrative requirements on application intentions and express these effects as willingness to pay for avoiding specific requirements. We also study heterog...

  • Making groups work for women in pastoral communities through group cohesion and spousal support trainings in Ethiopia
    Last registered on June 23, 2026

    This study aims to evaluate the impact of training programs delivered to members of micro and small enterprises (MSEs), as well as to the spouses of female MSE members, on the economic and non-economic outcomes of pastoralists and agro-pastoralists. The first treatment group receives soft skills and group cohesion training delivered through a technology-based (tech-led) modality, while the second group receives the same training delivered by human facilitators (human-led). Furthermore, to foster spousal support for female MSE members, the husbands of female participants receive what we refer to as “spousal support” training through a human-led modality. This is complemented by an edutainment component provided to a randomly selected half of the spouses

  • Improving labor market matching and screening in Addis Ababa
    Last registered on June 23, 2026

    This RCT studies whether recommending additional vacancies to jobseekers in Addis Ababa based on a combination of jobseeker and firm preferences increases employment and vacancy filling rates simultaneously. We additionally study whether allowing jobseekers to signal their skills (with a focus on soft skills) through certificates further enhances the effects of recommendations.

  • Discretion, Information, and Credit Screening: Evidence from Italian Loan Officers
    Last registered on June 23, 2026

    This project studies how loan officers and credit professionals evaluate credit applications, and how applicant identity and additional hard information affect credit assessments. We implement an online randomized vignette experiment in Italy with respondents involved in the evaluation of credit applications. Each respondent evaluates three hypothetical credit requests randomly selected from four possible cases: two loans to micro or small firms and two first-home mortgage applications. Within each vignette, we randomize applicant identity using names that jointly signal gender and geographic origin, as well as age, firm age or current employment/self-employment tenure, and the applicant’s relationship with the bank. After an initial assessment, respondents receive additional randomized...
