Although economists and other social scientists have worked hard trying to disentangle what factors can explain differences between performances across schools, there are few studies about the impact of management on education. For example, the discussion about management on productivity has not caught strong attention from economists (Bloom et al., 2012, p. 2). In the case of causal evidence coming from randomized trials, the gap is even larger. Despite a growing number of randomized experiments conducted by social researchers to address critical scientific questions on policies in the last decades, very few trials have been undertaken to explore the causal consequences of management on productivity (Duflo, 2007; Fryer, 2017). Thus, this research intends to reduce this knowledge gap by...
In South Sudan, the delivery of assistance is shaped by constraints on infrastructure, access to technology, and financial literacy. This study evaluates the comparative effectiveness of delivering transfers via mobile money relative to traditional cash transfers in a low-connectivity, fragile setting. While digital transfers have the potential to reduce transaction costs, improve the safety of delivery, offer recipients greater flexibility in managing their resources, and expand financial inclusion, limited access to mobile networks, low penetration of mobile phones, and poor mobile vendor infrastructure may constrain their impact. Using an experimental design, we compare outcomes across delivery modalities, focusing on take-up and use of mobile money, welfare, financial inclusion,...
Improving public trust in public health services is a challenge in many developing countries. One of the possible reasons behind this may be low level of public trust in public health services. This study aims to clarify whether providing truthful positive information about public health services can improve people’s trust in public health services.
We study whether beliefs about the labor-market exposure to artificial intelligence (AI) causally affect the demand for redistribution. The experiment is embedded in wave 15 (fielded in the second half of 2026) of a long-running Japanese national online panel (the NIRA-Okubo survey, where NIRA is the Nippon Institute for Research Advancement; about 10,000 respondents per wave since April 2020). Early in the survey, all respondents state a prior belief: out of 100 working people in Japan, how many are in jobs with high exposure to AI (numeric answer, 0-100). A randomly selected half of respondents is later shown a short, truthful statement, based on published staff estimates of an international organization, about the estimated share of working people in Japan in jobs with high exposure ...
This study examines how employees respond to organizational policy changes and the justifications managers provide for those changes. A managerial pre-study was conducted to obtain managers’ policy decisions and accompanying justifications. Following completion of the managerial pre-study, we have revised the implementation plan for the employee experiments. The revised employee experiment uses a 2 (Policy Change: Abandon vs. Double Down) × 2 (Justification: Business vs. Moral) between-subjects design in the context of an organizational sustainability policy. The study examines how the direction of a policy change and the manager’s justification jointly influence employee responses, including honesty and turnover intentions. The revised employee experiment is limited to the Sus...
This study uses a randomized controlled trial to evaluate whether involving other household members in the training process of Antioquia's Departmental Care System (SCA) shifts the distribution of unpaid care work and related outcomes among women caregivers in Colombia. The experiment is embedded in the 2026 cohort of the SCA's formative program across 51 prioritized municipalities. Using a 2x2 factorial design, we evaluate two household-inclusive interventions: a WhatsApp-based information campaign delivering content for each thematic component of the formative program, in which both the participating woman and a co-resident adult household member she nominates receive an infogram and audio message summarizing that component's main learning and prompting household conversation on care ...
Marriage is among the largest financial decisions an Indian family makes. Dowry transfers at a daughter's wedding can consume more than a year of household income, and the quality of her match shapes her economic security, autonomy, and well-being for decades. How wisely families allocate financial resources across daughters therefore matters enormously. Parents typically arrange their children's marriages in birth order. If a good elder match functions as a positive signal to the marriage market, improving how prospective grooms' families view the household, then parents can capitalise on this spillover by strategically allocating more resources to the elder daughter's match. If no such spillover exists, or if parents misjudge it, the same allocation deprives the younger sister of reso...
Poor staff motivation can hinder the delivery of public services. We study how to design information to motivate front-line service providers in a field experiment with Community Health Workers in Guinea-Bissau. Study participants attend a one-day training workshop. We randomly assign half to a module conveying information about program effectiveness which blends scientific evidence with culturally relevant anecdotes. The primary measure of motivation is the performance in a real effort task. This involves phoning households to collect health information and deliver recommendations. We then investigate potential mechanisms via several follow-up surveys. Also, we track participants' performance in their role as CHWs in the months after the workshop. Finally, we follow up with households ...
We study what respondents in Denmark know and think about the functioning of the public pension system. Thanks to the match of survey responses to administrative data from Statistics Denmark, we can test whether respondents have accurate information about their own pension situation. We randomly provide a subset of respondents with information about their pension rights and features of the pension system, with a focus on fiscal sustainability, redistribution within and across generations, or pocketbook motives. We then study how information on these dimensions changes respondents’ views on pension policy and the role of government, and their stated political behavior. In a parallel, non-experimental component, we exploit quasi-random variation in individuals' normal retirement age ge...
This pre-analysis plan details a randomized controlled trial in rural Burundi designed to evaluate the adoption and impact of electric cooking (e-cooking) appliances among newly electrified households. Currently, over 90% of households in the study setting rely on biomass fuels like charcoal and firewood, which contributes to deforestation, increases local air pollution, and limits rural electricity demand. The study aims to identify which appliances and subsidy combinations maximize electricity demand, assess the environmental and economic benefits, and determine if carbon markets can cover appliance costs. The experimental design cross-randomizes the provision of e-cooking technologies—pressure cookers, induction stoves, hot plates, or a combination—and subsidy levels (free versus ins...
