AEA RCT Registry currently lists 12083 studies with locations in 170 countries.
This randomized controlled trial (RCT) examines the impacts of a publicly provided digital clinic that offers digital primary care services to consumers. Our intervention grants access to a public digital clinic that provides chat-based primary care consultations via a mobile phone application and website, including care needs assessment, diagnoses, follow-up care recommendations, and prescriptions. The digital clinic supplements traditional public primary care services, including in-person visits and phone consultations. The trial takes place in Ostrobothnia, Finland, a healthcare district serving a population of 178,000 residents. We randomize access to the digital clinic at the household level, providing access to 50% of the households. By doing so, we aim to evaluate whether digital...
Commercial agglomeration is observed in many parts of the world. There are several theoretical explanations as to why commercial clusters occur, but empirical research is limited. This study attempts to examine the mechanisms of commercial agglomeration by surveying wholesalers located in one of the major wholesale markets in an emerging Asian country. When the market was destroyed by a fire in 1994 and rebuilt in 1997, about 1,400 slots were randomly assigned to garment wholesalers by a lottery. By collecting historical data over the past 25 years, we will analyze how the initial random allocation was transformed into the clustering of product types observed today. By taking advantage of the setting where a large number of similar-sized firms in the same industry operate, we conduct a ...
We conducted a randomized controlled trial of management trial in the automotive sector targeting Tier 2, mostly local suppliers. Our training featured the Kaizen approach, which is a Japan-pioneered production management approach. We analyze its impacts on adopted management practices, business performance, and corporate cohesion. Corporate cohesion has been one of the major social problems in this formally segregated country. We test whether the improved production management that requires the cooperation of managers and workers improves corporate cohesion.
How redistribution affects the real economy is one of the central, unanswered questions in development economics. The effect of redistribution on the welfare of non-beneficiary households is theoretically ambiguous: there could be positive spillover effects through increased aggregate demand (a multiplier effect), or negative spillovers from price inflation or crowd-out by business expansion for non-beneficiaries. The NGO GiveDirectly provides large cash transfers to rural households in Kenya. We utilize an RCT to study the spillover effects of cash transfers on household welfare, prices, enterprise creation and local public finance and will make use of spatial variation in treatment density in order to estimate these effects.
This study tests whether point-of-sale disclosure of the full cost of installment payments / buy-now-pay-later (BNPL) affects consumers' payment choices and purchasing behavior. In the treatment condition, sales staff disclose the upfront payment price, the total amount payable under the installment option, and the implied overpayment before the customer finalizes the payment decision. In the control condition, stores follow the standard price presentation and sales process. The primary outcome is the share of purchases made using installment/BNPL payment. Secondary outcomes include total sales, average transaction value, conversion, product mix, and returns where available. The study will be conducted over approximately three months, with two phases, across a small number of co...
Research shows that U.S. employers still exhibit racial biases against Black job seekers, and Black employees in predominantly white workplaces often experience higher turnover rates and fewer promotions than their counterparts. However, limited research has examined whether and how the racial identity of business leaders may disrupt discriminatory practices and behavior. Evidence suggests that diverse leadership among high-ranking individuals in a company can lead to increased managerial and staff diversity. Our proposed study examines how Black leadership in the talent management process impacts the screening of diverse job candidates. To investigate this, in a field experiment, we will post an authentic job opening and recruit freelance hiring professionals to assist us in the init...
In this experiment we study intergenerational education persistence and investigate to what degree perceptions of vocational and university education affect individuals’ preferences for different education choices. We conduct a survey experiment in a representative sample of adults in Germany in which respondents choose which of two hypothetical career trajectories they would recommend to a hypothetical adolescent at the end of secondary school. We include an oversample of parents of 0- to 6-year-old children, which allows separate analysis of this subgroup. All participants are randomly assigned to a labeled (treatment) or an unlabeled (control) group: in the control group, respondents are provided with information on earnings over the lifecycle for two different paths; in the treatmen...
In-service teacher training programs offer a potential solution in alleviating the global learning crisis in many low- and middle-income countries, which show low student learning despite high enrolment. However, significant supply side barriers limit the scalability of high-quality in-service training. This project aims to scientifically assess a scaling approach for teacher professional development in Tanzania. The evaluation is designed as a randomized controlled trial (RCT), to identify the causal effect the two scaling approaches have on student learning outcomes. Additionally, this project incorporates teachers’ perspectives on pedagogical innovations and teachers’ job satisfaction and self-efficacy as a potential mediator of causal mechanisms. By collecting a extensive body of su...
State efforts to improve women’s access to justice often depend on women frontline workers who are themselves marginalized within the very institutions meant to protect them. We examine this tension in India, one of the world’s most gender unequal countries, and focus on policing, one of the state’s most male-dominated public institutions and one long seen as unwelcoming to women both as officers and as complainants. We partner directly with the Punjab Police to study the Punjab Police Mahila Mittar (PPMM) program, which assigns female constables to help desks serving survivors of gender-based violence. Although the PPMM program aims to make policing more responsive to women, the constables who staff these desks often remain professionally and socially marginalized within a force that i...
This project investigates how AI integration modulates team dynamics and performance across both flat (leaderless) and hierarchical (leader-led) organizational structures. In leaderless settings, the research evaluates the impact of AI on collective output and individual member confidence, specifically examining whether the introduction of AI obscures the "star effect" typically driven by consistently high-performance individuals. Within the leadership framework, the study determines how the sophistication of AI assistance—ranging from standard AI and certainty AI to personalized AI interacts with the method of leader selection. By comparing teams with self-promoted versus randomly assigned leaders, the research aims to analyze how leadership legitimacy and AI modality jointly influence...
