Using new cross-country survey and experimental data, we investigate the nature of beliefs about wage inequality and the effect of these beliefs on people’s support for redistribution with over 9000 respondents across six high-income countries (Australia, France, Japan, Sweden, the United Kingdom and the United States). This study combines a flexible elicitation of beliefs about the distribution of full-time wages within each country and a randomized survey experiment where respondents are allocated into one of three groups, two of which receive different types of information about wage inequality.
A large share of the workforce works in self-employed in developing countries, a hard to tax segment, compared to salaried employees. We study the perception of fairness of the tax system, focusing on the horizontal inequity between salaried and self-employed individuals, in five large low and middle-income countries. We conjecture that the prevalence of self-employment, strengthens horizontal equity concerns, which in turn lowers demand for tax interventions, and especially direct income taxation. To test this hypothesis, we conduct online surveys eliciting individual perception on horizontal equity, tax fairness, relation to vertical equity and how these preferences relate to the tax instruments used by their governments. To test whether increased awareness of horizontal inequity affe...
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 ...
