Individuals invest in human capital under uncertainty about their future labor market outcomes. Vocational training prepares students for a specific career path, but the distribution of potential occupations is generally wide, and many may lack information about dispersion of these outcomes and their own proficiency in transferable skills—leading to underinvestment in portable human capital. We test whether providing concise, data-driven information can correct these misperceptions and shift investment toward transferable skills. In partnership with SENAI-SP, Brazil's largest vocational training provider, we conduct a 2×2 factorial experiment among approximately 34,000 students across roughly 100 schools, 1,200 classrooms, and 47 vocational tracks in São Paulo. Classrooms are randomized...
This study examines how individuals adjust their financial behaviour when faced with a sudden liquidity shock combined with changes in tax enforcement. In a laboratory experiment, participants repeatedly allocate income between a formal, taxed deposit account and an informal, untaxed cash holding. In each round, participants must finance a mandatory expenditure by allocating payments between deposits and cash. Expenditure from cash is subject to a friction cost, capturing the relative difficulty of using cash compared to digital payment methods. The experimental design compares behaviour across three treatments: a baseline with no shock, an unanticipated shock, and a pre-announced shock. In both unanticipated shock and preannounced shock treatments, a policy intervention invalidates ac...
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...
We design an experiment to document the validity of rational inattention models. Our design evaluates these models in direct (choosing intended posteriors) and natural (choosing information structures) frames. The former frame implements a decision variable closest to the model’s primitives, while the latter is more natural for experimental settings. By observing the acquired information in either frame, we can determine which class of rational inattention models aligns with the decision-making processes in the lab. These frames provide insights into the validity of these classes in rational inattention models, which are often tested solely based on choice data without observing the chosen level of informativeness. Assessing the consistency of their behavior between the two frames allow...
We study the relationship between the degree of competition firms face on the market for their output goods and hiring discrimination, in particular against women. We do so using a lab-in-the-field experiment with (planned) 500 owners or managers (employers) from the Greater Cairo area in Egypt. For the purpose of this experiment, we partner with a firm in the data processing sector offering real temporary jobs advertised broadly on local social media sites. We survey around 100 applicants, and based on a suitable subset, we create profiles. We show subsets of these profiles to the employers during the survey for them to select prospective employees among the candidates who will be offered the real jobs in the firm. Employers receive a payoff based on the productivity of the worker ...
Large employment and unemployment gaps persist between refugees and other migrants across Europe; refugees are 11.6 percentage points less likely to be employed and 22 points more likely to be unemployed than otherwise similar migrants (Fasani et al., 2022). Linguistic barriers are repeatedly identified as the key obstacle for economic and social integration (Lochmann et al., 2018). A growing experimental literature demonstrates that combining language training with job-search or work-practice components can generate large gains in refugee employment. Randomised controlled trials of refugee integration in Europe have examined a variety of interventions, such as occupation‑specific job‑search intermediation in Germany (Battisti et al., 2019), intensive counselling in Sweden (Andersson Jo...
Air pollution is a significant problem, especially in big cities and industrial agglomerations, and thus affects a substantial part of the population. Permanently exceeding the concentration limits of some pollutants has a very significant impact on the health of the population, especially children and other vulnerable groups. The research deals with air pollution exposure in children and the effect of awareness on change in behaviour, attitudes and preferences. The individual exposure of children to air pollution is determined using personal samplers. The parents of the children are subsequently given detailed individual reports on the results of their child's measurements, including comments and descriptions. The issue of air pollution and potential health impacts is also explained. P...
Globally, one-third of married women experience abuse from their husbands in their lifetime. For some countries, this rate is even higher (e.g., 72.6% in Bangladesh). Intimate partner violence (IPV) creates tension, fear, and anxiety among women, which might affect women’s preferences. We expect that the experience of IPV will make women more risk-averse, have lower trust in other people, and have more doubts about the future. It might also affect women’s willingness to be involved in household decisions. To investigate whether the recollection of the recent experience of IPV affects women’s risk preferences, time preferences, social preferences and willingness to be involved in household decisions, we will use a survey experiment with married women in Bangladesh. The survey includes a ...
Essential public-sector workers in low- and middle-income countries (teachers, health workers, police officers) operate under chronic stress, exposure to community violence, and institutional neglect of their mental health. Burnout, anxiety, and untreated trauma are pervasive among these frontline workers, yet rigorous evidence on scalable interventions to support their wellbeing remains nearly nonexistent. This gap matters not only to the workers themselves, but also to the quality of public services they deliver. We provide experimental evidence on whether socio-emotional resilience training can improve the mental health and professional effectiveness of essential workers, focusing on public school teachers in Guatemala. We evaluate SanaMente, a trauma-informed training program that b...
Teaching children reading and English as a second language (ESL) skills---skills that provide lifelong returns---requires access to engaging, contextually relevant materials. For children outside of Western contexts, English-language story options often lack familiar settings, norms, problems, and characters. We aim to learn whether stories written with generative AI assistance can fill that gap by creating context-relevant stories that better engage children in India.
