This study is a three-year follow up to an evaluation of low-cost behavioral interventions integrated into a productive inclusion program in Ghana. While prior research shows these interventions prompt immediate behavior change, a significant gap remains in understanding whether these effects persist over time and if they translate into improved livelihood outcomes. The original randomized control trial showed positive impact on saving behavior, but delays limited follow through on investments. This longer-term follow-up aims to measure if these interventions lead to enduring savings habits, reinforced financial self-efficacy, and ultimately, increased financial resilience, business performance, and overall well-being. Additionally, the follow-up will update the cost-effectiveness...
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...
Ineffective agricultural extension systems and low-quality learning in schools are two important issues in developing countries. School-based agricultural extension (SBAE) has been shown by Lee (2025) to be a cost-effective platform to overcome the lack of extension officers and motivate school attendance. This study extends one step further to explore SBAE's potential to improve learning via using practical, experiential student experiences in agriculture as a teaser for scientific learning, thereby feeding back into agricultural households' understanding of agricultural technologies and adaptation to their needs. Specifically, we exploit the randomized scaling of SBAE to study the impact of adding an intervention, called "Learning to Learn" (LTL; Nourani et al, 2025). Using a sample o...
In many developing countries, elections are often accompanied by political violence. A recurring pattern is the escalation of protest beyond its initial target—from resistance against the government to attacks on civilians, media organizations, and private property. We term this grievance-exceeding protest, distinguishing it from grievance-directed protest targeting government actors. Using the case of Bangladesh’s 2024 uprising, we hypothesize that the perceived success of such escalation may have embedded grievance-exceeding protest into citizens’ democratic norms. We argue that misperceptions about political opponents sustain this norm: citizens overestimate opponents’ tolerance for grievance-exceeding protest, generating a security-dilemma dynamic in which both sides retain violent...
We design and evaluate a series of RCTs, based on the idea of creating settings with different types of social interactions among students in the educational environment. The interventions are based on designing a set of novel educational curricula on coding, and using them as a backdrop for inducing certain types of interactions. The context of coding allows us to create a learning environment that can mimic the classroom, with exogenous rules for interactions, performance, and rewards. That is, we create our own educational setting where interactions are induced in pre-determined ways within a learning/performance context. The larger RCT has three treatment arms, based on implementing three types of coding curricula that have distinct features and are hypothesized to have distinct eff...
We measure cannabis users’ willingness to pay for legal cannabis using an incentive-compatible procedure. We also use a controlled experiment to study the causal impact of i) information about the prevalence of potential health risks in illegal-market cannabis and ii) consumption experience with legal cannabis on the demand for legal cannabis products.
We conduct a randomized controlled trial (RCT) in the canton of St.Gallen, Switzerland. The study evaluates the social and economic consequences of legal access to cannabis. We also study the causal effects of different distribution channels.
This study explores how zero-interest loans, in the form of inventory, shapes sales performance and economic empowerment of rural female entrepreneurs. The study also explores the relative efficacy of such loans versus general marketing support to make them better salespersons. Beyond asking whether inventory-on-credit helps, we unbundle two mechanisms: the ability to demonstrate a product to customers, and the ability to offer instant delivery from stock on hand. The study uses a four-armed randomized controlled trial in Bihar (India): full inventory advance (demonstration and instant delivery), sealed stock (instant delivery, no demonstration), demo unit only (demonstration, no instant delivery), and a business-as-usual control. The results are expected to inform scalable models for r...
Diet-related chronic diseases impose substantial health and economic costs worldwide, making it critical to understand the mechanisms that drive persistent unhealthy food consumption. Traditional approaches to addressing this challenge focused on hard-end (e.g., taxes, subsidies, bans) and soft-end (e.g., nudges) measures to influence consumer decisions. However, these measures fail to account for a critical root cause of unhealthy food consumption: the indulgent and rewarding experience gained from consuming unhealthy foods. It is therefore important to account for consumption experience and memory when designing nudges or interventions to steer consumers to healthy food choices. This study fills this gap by utilizing attribution bias to examine how an induced positive consumption expe...
This study evaluates the impact of Gemini Guided Learning, an AI-powered instructional experience within Gemini that provides personalised learning through guided questions, step-by-step scaffolding, and multimodal resources rather than supplying direct answers, on mathematics learning in Junior Secondary Schools (JSS1 and JSS2, ages 13–15). The trial randomly assigns classrooms either to continue with regular teaching or to use Gemini in approximately half of their mathematics lessons over an eight to nine (8-9) week period. The same teachers are responsible for both treatment and control classrooms; all will receive training on how to use the tool, though it will only be applied in treatment classes. Mathematics performance of students and teachers will be assessed at the beginning an...
