Even when there are no official school fees, the financial burden of purchasing uniforms, books, and other school supplies prevents low-income students from remaining in school. In Uganda, researchers tested whether a school-based savings program improved academic performance and reduced dropout rates by enabling students and their families to save for school-related expenses.

Adolescent girls living in low-income settings may be trapped in a vicious cycle that prevents them from attaining employment and achieving better health outcomes and reproductive autonomy. Researchers will evaluate the impact of a program in Sierra Leone that aims to address this problem by bundling health education, vocational skills training, and micro-credit.

At the end of 2009, 22.5 million people were living with HIV in sub-Saharan Africa. The number of voluntary counseling and testing (VCT) facilities in the region has grown significantly over time, but utilization of the services has remained low. Researchers evaluated the Malawi Diffusion and Ideational Change Project (MDICP), which sought to explore the demand for, and the impact of, learning one’s HIV status.

Sanitation is essential to health and welfare, but as many as 2.5 billion people in the developing world have no access to improved sanitation. In slums near Nairobi, Kenya, IPA-affiliated researchers from UC Berkeley and the University of Maryland are testing how subsidizing the cost of connecting to the sewer system and providing information about the health benefits of improved sanitation affects the number of landlords who connect to the sewer system.

Commitment devices – in which people restrict their own choices in the near future to reach a farther off goal – have been shown to help people reach their goals, including savings goals. But are people good at choosing the right commitment contract? This evaluation in the Philippines tested the demand for and impact of a new commitment savings account with fixed regular installments. Clients could choose the stakes of the contract (in form of a default penalty) themselves.

Hundreds of millions of children worldwide are infected with parasitic worms. These worms are detrimental to children's health, their cognitive development, their education and their futures. Chronic illness caused by worm infections reduces literacy and adult productivity. This evaluation found that free deworming treatment substantially improved student attendance and health.

Why do so few people use fertilizer even though it can considerably improve yields? This project measures the increase in yield due to fertilizer and hybrid seed use in Western Kenya. It found that fertilizer is profitable, and providing information goes part of the way towards increasing fertilizer adoption. Programs that help farmers commit when they have money to use fertilizer in the future have a very large impact on fertilizer adoption.
