While enrollment in secondary school has increased significantly in the past 20 years, net enrollment rates remain below 70% in low- and middle-income countries (LMICs) (UNESCO Institute for Statistics, 2021). Factors such as engagement in paid work and early marriage draw adolescents away from schooling during these critical years of development. In Bangladesh, where a reverse gender-gap in enrollment has emerged in recent years at both the primary and early secondary levels, gender inequities remain in the intrahousehold allocation of educational resources, with boys receiving greater investment in the quality of schooling (Xu, Sonchoy, and Fujii, 2022). Furthermore, at the secondary level, dropout rates among girls outpace boys at 42% compared to 33% (GIRL Center Research Brief, 2020...
This project examines the effectiveness of air purifiers in improving indoor air quality and their impact on educational and behavioral outcomes in public school settings characterized by inadequate infrastructure and overcrowding. Conducted in collaboration with the Punjab Ministry of Education, our randomized intervention placed air purifiers in classrooms significantly more dilapidated than typical private schools. We assess the impacts on cognitive performance, classroom disruption (measured objectively through noise levels), and behavioral aspects such as moral values, cooperation, free-riding tendencies, and risk-taking behaviors—factors essential for effective teamwork and future labor-market success. Using baseline and follow-up assessments administered to grade 2 students at ra...
Digitalization in banking is leaving elderly clients at risk of losing access to financial services, yet little is known about how to effectively encourage technology adoption at an advanced age. In a companion field experiment (AEARCTR-0013985), we find that while internet banking training is highly effective conditional on participation, take-up of training among the group of elderly non-adopters is very low (2% initial response rate). This survey experiment investigates how the design of training invitation materials can increase older adults’ willingness to participate in internet banking training. We conduct an online survey experiment with around 1,000 German respondents aged 50-75 who do not regularly use internet banking. Respondents are presented with a hypothetical invitation ...
This study investigates the motivations behind charitable giving after the provision of a public good, following the approval of a new climate law through a referendum. An environmental NGO is launching its first fundraising appeal after this policy success, creating a setting in which the core policy outcome has already been secured. This context allows us to examine whether post-policy donations are driven primarily by expressive warm-glow motives or by instrumental considerations about continued impact. We implement a natural field experiment with 3,543 potential donors using a 2×2 design. The first treatment dimension varies the motivational framing of the appeal: the message either emphasizes expressive participation and the symbolic value of being part of a successful civic mov...
Despite general belief that Islam prevents women's labor force participation, existing micro-level empirical studies offer mixed conclusions. This study focuses on Pakistan, where the population is predominantly Muslim and the rate of female labor force participation (24.5%) is substantially below the global average. We conduct a laboratory experiment targeting male university students. While persistent social norms against women working outside the home are well-documented among older generations of male decision-makers, this study focuses on the younger demographic whose attitudes are supposed to be more malleable. We provide participants with two different types of information, both of which are checked and confirmed by a religious scholar. One type encourages female employment, whil...
Recent advances in artificial intelligence (AI) offer opportunities to improve healthcare delivery through AI-driven primary care consultations. However, patient acceptance remains uncertain. To inform healthcare policy and insurance benefit design, it is essential to understand the conditions under which patients would accept AI consultations instead of traditional doctor visits, especially the financial compensation or savings necessary to encourage adoption. This study aims to: Measure patients' willingness-to-accept (WTA) compensation for switching from traditional doctor visits to AI-based consultations for primary care. Identify how WTA varies based on AI attributes, including: Price differences Wait time differences Medical liability of AI for errors AI’s ability to pr...
This experiment investigates how individuals update beliefs and trade when exposed to aggregate information in the form of consensus price signals. Participants engage in repeated rounds of pairwise trading of a risky asset with uncertain payoffs. Each experimental session, conducted online via oTree with 6–12 participants, is randomly assigned to either a treatment condition—where participants receive a consensus price signal based on previous trading outcomes—or a control condition without such information. The design allows for clean identification of the causal effect of price informativeness on trading behavior and belief formation. Primary outcomes include trading behavior, accuracy, and convergence of beliefs; the secondary outcome measures the influence of the consensus signal o...
While market-based sanitation (MBS) has successfully expanded access for many, purely market-driven approaches often fail to reach the poorest and most vulnerable households due to significant financial barriers. To address this equity gap, we are conducting a two-arm cluster randomized controlled trial of a poverty-targeted sanitation subsidy program integrated with iDE's MBS programming in the Wolayita zone of rural Ethiopia. 104 villages (gotts) were randomly assigned to either a control group receiving status-quo MBS programming or a treatment group receiving MBS integrated with targeted financial discount vouchers for eligible poor households. Following a baseline household listing in September–October 2024, subsidies were distributed between January and February 2025. We are retur...
This study aims to improve agricultural productivity in Northern Ghana by identifying the most effective method for selecting "seed farmers" to disseminate information about Integrated Soil Fertility Management (ISFM) technologies (e.g., improved maize varieties, fertilizer application, and intercropping). While selecting central individuals in a social network is known to speed up technology diffusion, traditional methods of mapping these networks are often too expensive and time-consuming for practical use in developing countries. This Randomized Controlled Trial (RCT) tests a novel, low-cost targeting method designed to identify influential farmers without a full census. The study compares four specific strategies for selecting seed farmers: a) Network Theory-Based Targeting: Using ...
The goal of this research is to investigate biased beliefs about personal saving behavior. Biased beliefs in this study are operationalized as overplacement (one of three forms of overconfidence), comparing an individual’s beliefs about personal saving behavior to an individual’s beliefs about saving behavior of others. We will investigate whether specificity of referent characteristics affects the level of overplacement. Moreover, we will investigate whether the specificity of the referent characteristics interacts with the perceived importance of saving. We designed an online experiment where the specificity of the referent characteristics are systematically varied. The results of the experiment will have relevance for understanding the role motivation plays in overplacement about per...
