In recent years, individuals began producing air quality data (AQD) by purchasing and using air quality sensors. At a low cost to adopters, this personalized, real-time AQD can inform individual decision-making (e.g. air pollution responses) and contribute to publicly available pollution maps. Recent research shows that socioeconomic status predicts air quality sensor adoption, potentially exacerbating existing spatial inequalities in AQD and health damages from air pollution. However, willingness to pay for this technology and its usage patterns are not yet well understood, in particular among different socioeconomic groups. We conduct a field experiment in a socioeconomically heterogeneous, high pollution setting in the United States to evaluate the adoption and use of low-cost air qu...
Whose problems do investors see as worth solving? I experimentally study how investors evaluate a startup idea based on the socioeconomic background of the founder, the target customer, and the (in)congruence between the two. I am also interested in how the socioeconomic background of investors themselves affect these evaluations. I aim to contribute to the research on diversity and inequality in entrepreneurial funding in which socioeconomic backgrounds have been relatively understudied. I also provide implications on whose problems are deemed worthy of resources, and how to support the missing entrepreneurs from underprivileged backgrounds.
The study provides a methodological contribution to the circumstances under which personality tests can be used effectively in the context of supporting entrepreneurs in developing countries. It tests whether personality tests are valid in these contexts and assesses the degree to which individuals are able and willing to “fake” their personality test results. Furthermore, the study tests whether gender differences in honesty and stereotype threat affect outcomes of otherwise equally qualified individuals and evaluates the extent to which the use of high cognitive load can reduce “faking” and any gender-based disadvantage in the use of personality tests.
The experimental design will be used to infer the impacts of a financial education course integrated into the math curriculum for 9th and 10th grade students, as well as active learning methodologies trainings for their teachers. The program targets students from disadvantaged families, seeking to make school more attractive and effective for them. The intervention spans the biennium 2021 and 2022 and comprises three treatment arms: a single dose of the program for students and teachers (in the 9th grade); a second dose for students in the 10th grade, and a second for 9th grade math teachers. The evaluation seeks to account for the impacts of the program over students cognitive and non-cognitive development, teachers’ practices and motivation, their financial knowledge and behaviour...
Despite the potential to reduce diarrheal disease burden (Quick, et al, 2002), use of affordable point-of-use decontamination technologies such as chlorine tablets is low in many developing countries including Pakistan (0.3%, with 8% adopting any purification technology; Pakistan DHS, 2012-13). While price - even when low - can hinder adoption, free access induces only partial usage. For example, free delivery of chlorine solution in Kenya yielded a usage rate of only 34% (Dupas, et al, 2016). However, there is little evidence on ways to increase usage beyond this basic level induced by access. Akram & Mendelsohn (2017; hereafter, AM) explore an alternative hypothesis: If the households do not understand - or trust - expert opinion on benefits of usage and benefits are hard to measure, ...
This study will reveal how sending nudge-based messages to correct the false belief “I have antibodies for rubella” affects the uptake of rubella antibody testing and vaccination. In Japan, herd immunity to rubella can be obtained by achieving a 90% antibody prevalence rate for rubella in all generations. While the rate has reached over 90% among most generations, the rate for males born between 1962 and 1978 is approximately 80%, because they were previously excluded from the routine vaccinations and had few natural infections. Therefore, the Ministry of Health, Labor, and Welfare (MHLW) has set a policy goal of increasing the antibody prevalence rate of this generation of males from 80% to 90% to obtain herd immunity against rubella. To achieve this goal, free coupons for rubell...
Affect labeling, the process of putting feelings into words, has been shown in neuroscientific studies to have a calming effect on the brain and to reduce anxiety. This study examines the impact of affect labeling on self-reported levels of anxiety. We conducted an online experiment with three hundred participants from the United States, who were randomly assigned to either a control group or a treatment group. Both groups were exposed to news about a violent crime and then asked to report their level of anxiety. The treatment group also had the opportunity to express their feelings in an unrestricted way before reporting their anxiety level. Our results show that affect labeling has a significant negative effect on self-reported anxiety levels, suggesting that it can be an effective to...
The project examines the effect of digital and social skills on the likelihood that workers will be hired. For these hiring decisions, we particularly investigate for which work contexts (workplace characteristics, team member characteristics) workers with different types of social, digital and occupational skills are recruited. For example, firms differ in their IT investments or teams differ in terms of their work situation (e.g., division of tasks) and team composition (e.g., age, gender, qualification of team members). HR decision-makers in real firms are the respondents of our project. A vignette module is anchored in the BIBB Establishment Panel on Qualification and Competence Development, Wave 2023.
This pre-registration describes two different but related experiments: Explicit Randomization and Implicit Randomization. They will be run as treatments of a larger experiment and analyzed both individually and in comparison to each other. The experiments study the link between regret-avoidance and explicit/implicit randomization behavior in decision making under risk. We describe the experimental design, the hypotheses, planned analyses, and the sample size.
We designed and conducted a series of experiments in partnership with a large pharmaceutical company operating over 150 plasma donation centers, with the aim of promoting sustainable behaviors in the workplace. Our study employed social norms to nudge employees towards reducing electricity and plastic consumption and increasing recycling. We randomly assigned participating centers to four groups of three treatment arms, with one pure control group. Each center was involved in one experiment only. The interventions involved five key elements, including intervention, tier board tracking, education, signage, and communication. For reducing electricity consumption, we focused on how long freezer doors remained open. To reduce plastic waste, we focused on dropped collection materials that m...
