This study addresses how unethical behavior in scientific research impacts trust in science, contributing to a literature on the consequences of corruption and unethical behavior. We propose an informational delivery experiment with high school students in Brazil, where we present them with a summary of a suspected fraud scandal in behavioral science. We divide treated subjects into a "fraud" arm, where they only learn about the fraud accusations, and an "accountability'' arm, where they learn about the investigation and punishment processes involved; this allows us to tell apart the effects of learning about cheating from catching cheaters. We measure the effect on beliefs in science, the use of scientific evidence to update world views, real life attitudes towards science, and spillov...
Most research on mentoring and tutoring programs has primarily concentrated on how such relationships benefit the mentees. However, there is a notable lack of studies examining the effects on the mentors themselves. This study addresses this gap by assessing the impact of a mentoring program on the social skills of the mentors. Leveraging randomized control trial conducted in public schools in Bogota, Colombia, this research examines the outcomes of pairing university students with public school students for one year. These pairs consist of individuals from differing socio-economic backgrounds, with the public school students generally from low-income families and the mentors from middle- to high-income families. By exploring this unique setup, the study aims to determine how mentorshi...
We study the mechanism of why default nudge works. To investigate this question, we consider three factors suggested in the literature; ease, endowment, and endorsement. To consider how these factors affect default nudge, we conduct an online experiment and a fMRI experiment. In these experiments, we ask series of binary choice questions to the subjects in which subject faces the five treatments: i) no default nudge, ii) simple default nudge where one alternative is selected as default, iii) default nudge with ease where the questions are asked with many words so that the subject will find it easy to choose the default choice, iv) default nudge with endowment where the default choice is associated with endowment effect, and v) default nudge with endorsement where the default choice is a...
We use a field experiment at the biggest employer on a large college campus to examine how individuals make labor supply decisions when facing variable wages and a complex tax schedule.
We study depression stigma in the marriage market in India. We document the extent of depression stigma in the marriage market, elicit the penalty associated with depression with respect to dowry and partner education, and identify which beliefs correlate with this penalty. We pair this analysis with experimental evidence of the long-term impact of depression treatment on marriage market outcomes of untreated household members.
We conduct an online survey experiment in Germany to analyze how individuals' support for climate policy varies with certain characteristics of its implementation and with individuals' personal characteristics. In addition, we also want to explore how support for climate policy is affected by a pessimistic economic outlook. To this end, we conduct a conjoint experiment in the context of a randomised online survey experiment.
We seek to investigate the determinants of mobile money underadoption in Jordan on both sides of the market using a field experiment. Specifically, we elicit consumers' and merchants' willingness to pay for mobile money through an incentive-compatible mechanism and quantify the role of various behavioral factors that we suspect hinder adoption. Our treatments cover a wide set of behavioral factors that are commonly identified as significant barriers to adoption in previous research, such as attention, digital financial literacy, and trust, as well as rational explanations that deem underadoption in two-sided markets as a coordination failure.
In Germany and several other European countries, taxpayers can deduct from their income the cost of commuting between their home and first place of work. The specific design of such a commuter tax allowance has far-reaching implications for personal finances, social fairness, and environmental impact and is therefore the subject of a broad debate in many countries, including Germany. In a survey experiment among 3,000 participants in Germany, we assess participants’ beliefs about the current regulation in terms of social fairness, environmental impact, and own financial interests and how these beliefs relate to the support for different reform options. In addition, we provide a randomly assigned subset of participants with information about the social fairness and environmental impact o...
I investigate how disclosing information about selection for a beneficial opportunity, such as an educational program, impacts participation (take-up) of that opportunity. The conjecture is that depending on the information received and who knows about it, selection criteria can trigger personal and image concerns, which may be manifested positively (triggering pride) or negatively (triggering stigma). The program is offered as an opportunity granted by an international institution. It is free and self-paced. It consists of 9 online sessions of 30 mins each. The objective of the program is to help develop skills to better attain goals. Selection focuses on merit (high academic achievement) and identity (low socio-economic status). Targeted individuals are university students to wh...
Although autonomous vehicles (AVs) have the potential to improve road safety in the future, public support is limited. Existing research has shown a negative correlation between the perceived risk of AVs and the acceptance of AV policies. We aim to further investigate this relationship by surveying approximately 3,000 households in Germany. We introduce a novel measure of perceived AV risk and associated cognitive uncertainty that provides insights into risk perception beyond traditional Likert scale measures. To shift risk perceptions, we employ an information provision experiment and examine its impact on risk perceptions and associated cognitive uncertainty. In addition, we analyze the relationship between risk perceptions, cognitive uncertainty, and acceptance of AV policies. Finall...
