Generative AI economic benefits in aggregate are often cited. However, the productivity or efficiency improvements within organisations is an emerging topic. Recent research focused on knowledge work suggest productivity or efficiency improvements may be large, finding significant effects for certain types of tasks, with more benefits to less experienced workers. Evaluating the value/benefits and costs of GenAI in knowledge-driven organisations within a public sector may not be as clear-cut in a for-profit context. To provide some evidence, our study will test the impact of GenAI on two knowledge-work tasks among staff in the organisation.
A recent study by Loewenfeld and Zheng (2023) documented that individuals are correlation-sensitive and exhibit behavior patterns compatible with decreasing sensitivity to payoff differences (DSPD). These behavioral regularities can be explained by two competing theories: correlation-sensitive preferences, as characterized by Lanzani (2022), with concavity, or probability dominance, as advocated by Diecidue et al. (2020). In this study, we conduct a controlled lab experiment with students to examine the mechanisms underlying correlation sensitivity in decision making.
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...
