This study examines whether limited access to high‑quality demand and supplier information constrains the growth of small retailers in developing countries and whether an AI‑driven mobile application that pools sales data across shops can overcome this barrier. It will further test what the returns are to increasing the size of the data pool. One thousand Lusaka‑based retail shops will be randomly assigned in equal proportion to (i) an inventory‑management app only (control); (ii) the app plus lower-priced supplier recommendations generated from data pooled across a relatively small number of similar shops; or iii) the app plus lower-priced supplier recommendations generated from data pooled across a relatively large number of similar shops; or (iv) the app plus product recommendations ...
We examine the implications of providing privacy information online via a real-world information provision experiment.
Learning the local language is often recommended to foreigners to socially integrate into a new country. We study the extent to which acquiring the local language creates social opportunities for foreigners. Using a field experiment, we investigate the relationship between cultural assimilation via learning the local language and non-native individuals’ ability to socially integrate along two dimensions: (1) housing, and (2) amateur football clubs. We use online messages to contact landlords/realtors to view a property and ask football coaches to join a trial practice. We compare response rates across different email treatments.
Why do workers decline promotion opportunities even when advancement is feasible and associated with higher pay? This study investigates supply-side barriers to promotion by examining whether workers' willingness to accept leadership roles is limited by underestimation of the on-the-job learning due to their low current interpersonal skills. Motivated by our survey results of factory workers, we conduct a two-stage randomized controlled trial with vocational students and factory workers. Students are organized into three-person production teams that complete a sequence of manufacturing tasks designed to simulate a factory production environment. The experiment consists of two production rounds with opportunities to choose or accept a leadership role. The design introduces three sources ...
This study examines the impact of modifications to the Transferencia a Primera Infancia (TPI) in urban areas. The TPI is a conditional cash transfer (CCT) program available to households that are part of the JUNTOS program (Peru’s flagship CCT program) and have a pregnant woman or a child less than 12 months old. The study will examine the impact of increasing the benefit amount on household welfare, child health, and child cognitive development.
Background and target population As part of the fiscal year 2021-22 budget agreed to by California’s Governor and the Legislature, the California Department of Social Services (CDSS) is providing support and oversight for five pilot programs conducting a randomized controlled trial of guaranteed income (GI). The intervention targets two unique low-income populations facing a key life transition that puts them at higher risk for adverse outcomes: youth aging out of extended foster care and pregnant people. Eligibility criteria The eligibility criteria for each target population is as follows: Former foster youth (FFY) - Low-income according to Insight Center’s Family Needs Calculator based on county of residence and household composition at time of application - Exiting/exited ...
Nutritional needs vary for each person, shaped by their genetic profile, metabolic processes, and microbiome composition. Recent technological advances have stimulated innovative solutions for personalized dietary guidance, with Food Recommendation Systems (FRS) leveraging AI to provide tailored recommendations based on users' preferences and health goals. Yet, the current FRS is limited in integrating health profiles, preferences, and nutrition needs. To address this, the project aims to develop and evaluate the impact of applying an AI and natural language processing (NLP)-driven FRS that personalizes dietary suggestions based on individual health parameters, nutritional goals, and preferences. The impact of this project relies on improving dietary adherence, enhancing user satisfacti...
This randomized evaluation investigates the impact of a bundled contract-farming model on smallholder farmers’ productivity and climate resilience in Upper Egypt. Farmers in this region face acute exposure to climate risks, particularly extreme heat and limited irrigation, and are often trapped in a cycle of low investment and poor market access. This intervention offers credit to finance climate-resilient inputs for cash crops, coupled with guaranteed contracts and extension services. We randomly assign farmers to one of four groups: (1) offer credit only, (2) offer credit with a recommendation to participate in contract farming and extension services, (3) offer credit conditional on uptake of contract farming and extension services, and (4) control group with no intervention. This...
This study examines how AI assistance affects individuals' beliefs about their own abilities. We use a randomized field experiment to estimate the causal effect of AI assistance on individuals' perceived competence and related outcomes.
Jails admit nearly 11 million individuals each year, including a high number of inmates with mental illnesses, infectious diseases, and chronic diseases. Since the Supreme Court’s landmark decision in Estelle v. Gamble (1976), federal and state correctional systems (including prisons, jails, and juvenile detention facilities) have been constitutionally mandated to provide “reasonably adequate” health care to the incarcerated population. Yet, unlike health care systems that provide services to the nonincarcerated population, there is no legally-mandated accreditation system for health care provided in U.S. correctional systems, including jails. As a result, jails may struggle to provide needed health care services. This may result in increased morbidity and mortality in this vulnerable p...
