Researchers evaluated the effects of a free health insurance policy and UCTs of the same value on the economic, health, and psychological outcomes of informal workers in Kenya. Participants who received health insurance self-reported reduced stress and had lower cortisol levels; UCTs led to fewer children in the household being sick and reduced overall hospitalizations in the household. Neither intervention had meaningful impacts on economic outcomes or other metrics of health and healthcare utilization.

Researchers conducted a randomized evaluation to study the impact of a large-scale Community-Led Total Sanitation (CLTS) program in Indonesia on sanitation practices, attitudes towards open defecation, and child health. When implemented by external resource agencies instead of local governments, CLTS increased toilet construction, reduced roundworm infestations among children under five, and decreased tolerance of open defecation.

Researchers conducted a randomized evaluation to measure the demand for private tutoring services, estimate how pricing can influence take-up and enrollment in these services, and examine how enrollment and performance differs by gender and age. Researchers found that demand for tutoring services decreases with increased prices, but that higher initial prices could help identify students who are more likely to utilize the services.

In Kenya, researchers are studying the impacts of a program that combines vocational training with one-time cash grants to boost youth employment and entrepreneurship.

To test this theory, researchers evaluated a multi-faceted approach aimed at improving long term income of the ultra-poor in multiple countries, including Yemen.
