We conduct an online survey experiment in Austria to test whether a positively framed narrative about a Syrian refugee shifts attitudes toward immigration and preferences for redistribution. Approximately 1,000 respondents are randomly assigned to watch either a short video telling the success story of a refugee who founded a bakery in Vienna (treatment) or a video about the voting age of 16 in Austria (active control). We measure immigration attitudes along three channels: labor market concerns, welfare state concerns, cultural concerns and elicit beliefs about support for immigration as well as preferred government spending allocations, income tax progressivity, and general support for redistribution. We also elicit prior and posterior beliefs about immigrant population sha...
High employee turnover remains a persistent barrier to productivity in manufacturing firms. This study investigates the roles of pre-employment information, financial growth incentives, and job assignment mechanisms in mitigating turnover and improving worker-job matches. We conducted a large-scale field experiment with approximately 2,000 newly hired workers in a Chinese electronics factory using a 3 × 3 cross-randomized design. In the hiring stage, we test the effects of information frictions and perceived career growth on selection. Applicants are randomized into: (1) a pure control group; (2) an information treatment viewing a video on factory life and strict workplace regulations; or (3) a "growth path" treatment combining the video with information on on factory life, position-spe...
This study evaluates whether information framing and monetary incentives increase uptake of the seasonal influenza vaccine among community residents. Participants are individually randomized to one of four information arms: (i) no additional information, (ii) neutral factual information, (iii) positively framed information emphasizing the benefits of vaccination, and (iv) negatively framed information emphasizing the risks of non-vaccination. Participants are also exposed to an incentive module that offers either no subsidy or a randomly assigned subsidy or lottery amount ranging from RMB 10 to RMB 100. The study collects three survey waves: baseline, a midline follow-up 2–3 weeks after the intervention, and an endline follow-up at the end of the influenza season, approximately 3–4 m...
This registration covers the main Phase II randomized controlled trial of a school-based mentorship intervention in Meizhou, China, and is distinct from an earlier pilot conducted in a different location and registered separately. The study population consists of primary-school students in participating schools in Meizhou, covering grades 1 to 6 and approximately 3,147 students in total. The intervention assigns trained mentors to a subset of students during the study period. Randomization occurs in two stages. First, classrooms are randomized within school-by-grade strata into treatment-cluster classrooms or pure-control classrooms. Second, within treatment-cluster classrooms, students are randomized individually into mentorship treatment or within-class control. The primary estimand i...
Once African Americans gained access to public provisions ---such as swimming pools, parks, and desegregated education--- support for these public provisions declined. A nascent literature argues that racism and a backlash to the civil rights movement also contributed to the decline in the U.S. social safety net. Using two parallel experiments, we study the causal effects of providing information about the number of Black people receiving welfare and unemployment insurance benefits on support for these policies. We use measures of individual confidence in their pre-treatment beliefs to measure treatment intensity and study the interaction of the treatment with individual-level racial bias, both explicit and implicit. Decreased program support following information that there are more ...
Youth unemployment in Andalucia is among the highest in Europe. By contrast, on the firms' side, there is an unmet demand for workers with tech skills. AprenTIC tests whether intensive, occupation-specific digital skills training can improve the employment prospects and well-being of unemployed young people.
School violence, discrimination, and gender-based bullying remain persistent challenges in Bolivia despite progressive legal frameworks intended to protect children and adolescents. Recent research conceptualizes bullying not as a dyadic conflict but as a collective social process in which bystanders play a decisive role in either sustaining or interrupting aggression. This study evaluates a behavioral intervention designed to activate prosocial bystander behavior by reshaping the social meaning and incentives associated with aggression and defense. The intervention employs game-based mechanisms to simulate peer interactions in a controlled environment, using visual, emotional, and strategic nudges to alter how social status is earned within the group. Rather than directly discouragi...
This factorial survey experiment investigates hiring discrimination based on religious identity in Belgium. Recruiters evaluate fictitious job candidates whose profiles vary systematically across multiple characteristics, including religion (Islam or Christianity), visual signals or religion (hijab, beard, cross pendant), extracurricular activities (religious or general volunteering), ethnic background signalled through names (minority represented by Turkish and Polish names, majority by Belgian names), and gender (male or female). The study simulates the first stage of a recruitment process, using an HR software package to present the profiles to real recruiters. Outcomes such as the likelihood to invite the candidate to a job interview and perceived candidate skills are analysed.
This study explores how access to AI-generated solutions influences problem-solving behavior and performance in 16–18-year-old students. Participants are randomly assigned to different conditions based on when they receive AI help and whether the AI solution is correct or incorrect, plus a no-AI control group. They complete an incentivized task with AI access and a second task without it to measure effects on independent performance.
This pre-analysis plan describes online survey experiments conducted in Germany to study preferences over relative income within couples. The surveys, implemented in partnership with Bilendi, consist of three distinct modules: (i) a qualitative satisfaction survey that studies the qualitative nature of partners’ preferences over relative income, (ii) a quantitative choice survey experiment that identifies the magnitude of these preferences, and (iii) a vignette-based beliefs survey experiment that examines potential mechanisms underlying them. The plan pre-specifies the survey design, sampling procedures, exclusion restrictions, outcome measures, and estimation specifications.
