The goal of this experiment is to validate a set of AI-generated profile photographs that will later be used in a factorial survey experiment involving recruiters and HR professionals. The photographs are designed to represent young job candidates whose ethnic background is visually ambiguous, while allowing the addition of specific religious cues (e.g., headscarf, cross necklace, beard). The pre-test serves two main objectives. First, it verifies that the baseline photographs do not strongly signal a specific ethnic background. Second, it evaluates whether the selected photographs are comparable in terms of perceived physical attractiveness.
Women are underrepresented at every level of the corporate ladder. A growing and important experimental literature suggests that women are both more likely to avoid competition and drop out of competitive environments after experiencing disappointment than men. These laboratory measures seem also to predict career choices and, hence, partly explain the gender gap. We study the role of perceived unfairness in explaining gender differences in willingness to compete again in response to losing a competition. We ask whether men and women differ in how they respond to losing or winning a competition and whether these differences increase or decrease in presence of unfair conditions. Moreover, we aim to understand which women and men drive the gender gap. For this purpose, we run a post-exper...
We study whether individuals form motivated beliefs about others' preferences when such beliefs can rationalise self-interested behaviour. In an online experiment, participants report their own willingness to work (WTW) on real-effort tasks and predict a counterpart's WTW. Participants are randomly assigned to a role (Employer or Worker) and an incentive condition (Low or High). Employers make a payoff-relevant decision about how many tasks to assign their counterpart, while Workers act as pure predictors with no such stake. We test whether Employers report higher beliefs about a counterpart's WTW than Workers, and whether stronger incentives to assign tasks widen this gap. Using higher-order beliefs, we further examine whether individuals anticipate motivated reasoning in others, and w...
This study uses an online experiment to examine how consumers respond to different types of cash rebates linked to environmentally relevant consumption choices. Participants make repeated decisions about how many units of a product to purchase under a fixed price that reflects a carbon charge, with lower consumption associated with greater environmental benefits. We compare behavior under several treatments inlcuding a no rebate control, a guaranteed cash rebate, and several probabilistic rebate schemes that differ in the likelihood of rebate payment. The study is designed to assess whether probabilistic rebates generate similar behavioral responses to guaranteed rebates, and to examine whether responses vary systematically with the probability of receiving a rebate. This experiment con...
Many young people enter the labor market with few qualifications, limited information about available opportunities, and little experience navigating employment services. Governments often respond by offering career guidance, training, job search assistance, internships, or subsidized employment. Yet participation in these programs is frequently low. Young people may not enroll, may drop out early, or may attend meetings without taking up the investments that could improve their employment prospects. This paper studies whether financial incentives can address this problem. We evaluate a randomized conditional cash transfer linked to participation in the French national career guidance program for young, low-skilled jobseekers. The program was administered by local Job Youth Centers and ...
We evaluate the causal effect of an intervention that combines gender-sensitive teaching practices with the pedagogical use of Matific, a gamified mathematics platform powered by adaptive artificial intelligence, on reducing gender gaps in mathematics achievement through reductions in girls' mathematics anxiety among students in 3rd- and 6th-grade public schools in Uruguay.
When interacting with others, individuals are uncertain about whether they will encounter pro-social or anti-social behavior. In such interactions, even a single observation can trigger biased beliefs about entire groups. We conduct a laboratory experiment in which participants simultaneously receive statistically irrelevant information about their in-group and out-group, with treatments varying whether both signals are pro-social or anti-social. Since the informational structure is identical across groups by design, any subsequent difference in cooperative behavior toward in-group versus out-group members must reflect asymmetric biased beliefs. We hypothesize that individuals overweigh signals that confirm existing group stereotypes, generalizing negative information about out-group me...
In the Baby’s First Years (BFY) study, one thousand infants born to mothers with incomes falling below the federal poverty threshold in four metropolitan areas in the United States were assigned at random within each of the metropolitan areas to one of two cash gift conditions. The sites are: New York City, the greater New Orleans metropolitan area, the greater Omaha metropolitan area, and the Twin Cities. IRB and recruiting issues led to a distribution of the 1,000 mothers across sites of 121 in one site (the Twin Cities), 295 in two of the other sites (New Orleans and Omaha) and 289 in New York. (The investigators have also randomly sampled 80 of the participating families in the Twin Cities and New Orleans to participate in an in-depth qualitative study, and later in the study inter...
We design an experiment to test for discrimination.
This pre-analysis plan should be read as an addition to the pre-analysis plans AEARCTR-0010425 and AEARCTR-0016856 submitted to the AEA RCT registry, concerning the same project. The project studies how individuals trade off ensuring fair inequality and avoiding unfair inequality in a spectator design. We collect additional data to elicit participants’ willingness to pay for ensuring fair inequality and for avoiding unfair inequality.
