We investigate the role of customer reviews and host demographics in statistical discrimination within the sharing economy (specifically in online rental markets). Using a controlled experiment in an Airbnb-like setting, we measure how a host's race, a host's gender, and customer reviews interact to affect accommodation demand. We create fictitious listings using scraped data from Airbnb and systematically vary host characteristics across three primary dimensions in a fully crossed 2x2x2 factorial design: Host Race (Black/White), Host Gender (Man/Woman), and a Review factor (High/Low). To isolate specific mechanisms of review-based discrimination, the exact nature of the Review factor varies across three between-participant treatments, manipulating either review quantity, positive infor...
This project aims to investigate if there is agreement regarding inequality aversion among the Swedish public, political, and medical decision-makers, in a discrete choice experiment. Subjects choose between two outcome distributions, where one choice is higher in life expectancy but with a higher variance between groups in the distribution. Furthermore, we consider whether the results are affected by whether a choice is made behind a veil of ignorance or not, a relevant distinction for decision makers who in practice make their decisions without a veil of ignorance. An information experiment is then performed to assess whether decision-makers can be influenced to make choices more in line with the general public's preferences. Half of the decision-makers are provided with the most popu...
The Paraguayan economy has a high level of labor and business informality, which is one of the main challenges for the country's productive and fiscal development. According to recent estimates by the Permanent Household Survey (EPH), approximately 65% of workers work in the informal sector, without access to social security or compliance with tax obligations. This situation limits collection, reduces labor protection, and makes it difficult to consolidate an equitable tax system. In response to this challenge, the Paraguayan State, through the Dirección Nacional de Ingresos Tributarios (DNIT), implemented the Simplified Regime for Small Businesses (RESIMPLE), in order to facilitate the incorporation of microentrepreneurs into the formal system through simplified procedures and redu...
The fall-army worm (FAW) increases food insecurity and income uncertainty in Uganda due to its sizeable negative effect on maize yield. Agroecological Integrated Pest Management (IPM) provides a promising approach to mitigate maize damages while minimizing environmental harm from control methods. However, agroecological IPM is also costly for farmers in terms of initial investments and maintenance (labor) costs. This study evaluates whether signaling opportunities at different costs may help overcome these costs and impact adoption decisions of an agroecological IPM package. We also compare the effect of signaling to the effect of loss/gain framing for a material incentive. In addition, we determine the effectiveness of an agroecological IPM approach on agricultural outcomes. The study ...
Through the lens of an interdisciplinary approach -embracing quantitative gender economics, innovation research and gender studies- interactive theater activities are planned with the aim to elicit biases and obstacles to inclusion and diversity in academia, as well as to raise awareness. Building on these interactive theater experiences, a short online experimental survey will be designed, and implemented, to explore attitudes and opinions about gender inclusion in academia.
This study evaluates the impact of promoting the use of GPT EconometríaUAI, a conversational AI assistant, on undergraduate students’ learning outcomes in econometrics. The intervention will be implemented during the second semester of 2025 at Universidad Adolfo Ibáñez across seven sections of the Econometrics course. Students will be individually randomized within sections into treatment and control groups. The treatment group will receive a series of emails encouraging the use of GPT EconometríaUAI for study support, while the control group will not receive such promotion (placebo emails may be used). The primary outcome is student achievement on the first midterm exam. Secondary outcomes include satisfaction with the course and students’ perceptions of their learning and study exper...
As countries transition toward energy systems with higher penetration of renewable generation, balancing supply and demand is becoming increasingly complex. Demand flexibility provides a mechanism for customers to respond to system conditions by lowering peak demand and reducing grid congestion, thereby reducing reliance on carbon-intensive generators. We test the effectiveness of this mechanism by conducting a large randomized controlled trial in Spain to evaluate how behavioral and financial incentives can motivate households to reduce electricity consumption during periods of grid stress (“Saving Sessions”). With a sample of 108,163 residential customers, we will assess the effectiveness of several behavioral and financial incentives in shifting short-term household demand during eve...
India ranks at or near the bottom in measures of school management quality (Bloom et al 2015, Lemos et al 2021). In 2020, India adopted a National Education Policy (NEP) mandating 50 annual hours of continuous professional development (CPD) for school leaders. We evaluate an RCT of a school leadership development program for public secondary schools in Karnataka, India. The program aims to improve student learning and engagement by training school leaders to implement School Improvement (SI) plans in three areas: 1) student learning, via remedial classes in math and language; 2) student engagement, by promoting student inclusion and leadership through school clubs and participation in daily morning assembly; and 3) parent engagement, by increasing participation in parent-teacher meeting...
A growing body of research, pioneered by Dana et al. (2007), has documented the prevalence of strategic ignorance in social decisions (e.g., Matthey and Regner 2011; Grossman 2014; van der Weele 2014; Feiler 2014; Exley 2016; Grossman and van der Weele 2017; Momsen and Ohndorf 2020, 2023; Serra-Garcia and Szech 2021): although people frequently incur a private cost to bring about some social benefit under conditions of full information, when the social benefit is uncertain, a surprisingly large number of people avoid easy opportunities to resolve this uncertainty and revert to selfish behavior. Although ignorance may stem from confusion or lack of interest, some individuals avoid information for strategic reasons, such as maintaining positive self - or social image (Nyborg 2011, Grossm...
This study pursues both empirical and methodological objectives. On the empirical side, it builds on Hirschman’s (1970) exit–voice framework to examine how employed individuals evaluate core employment conditions and how these evaluations translate into two distinct responses to dissatisfaction: exit, defined as willingness to change positions, and voice, defined as willingness to participate in industrial action. The design allows the analysis to move beyond preference measurement by linking workers’ evaluations of job attributes to behavioural intentions across different institutional contexts. On the methodological side, the study contributes to the labour-economics literature on wage–amenity trade-offs and institutional framing in stated-preference experiments, where most preferenc...
