More than two billion people around the world lack access to clean drinking water, and current approaches to increasing access have fallen short. Researchers conducted a randomized evaluation to test the impact of delivering clean water directly to households on the valuation of clean water, and other water-related benefits in India.

Researchers evaluated the impact of providing teachers with access to high-quality online lessons and implementation support on student achievement in mathematics. Providing teachers with access to the lessons, reminders, and implementation support significantly increased student achievement.

This study evaluated the impact of subsidies and two different marketing messages on the take-up of insecticide-treated bed nets by rural households. Take-up did not vary with the framing of marketing messages but was highly sensitive to changes in price. Gaining access to a highly subsidized bed net in the first year also increased households’ willingness to pay for an additional net a year later.

Researchers in Udaipur, India, evaluated the impact of a village-level iron fortification program on the physical health of local families in 134 villages. Despite high take-up rates at the beginning of the study, overall take-up rates fell by the end of the evaluation. Results showed a significant difference in anemia rate and physical health between the treatment and comparison group when program take-up was high, but no difference when it was low.

Researchers conducted a randomized evaluation to test the impact of providing information about the quality of migration agencies to potential migrants on migration choices and welfare. Information reduced the rate of migration in the short term, which lowered workers’ use of low-quality agencies, but did not change their intentions to migrate in the future or beliefs about the returns to migration. Those who did migrate received better pre-departure training and reported higher-quality job experiences abroad.

Researchers in Zambia found that the use of chlorine decreased with higher prices, but this decline was partially offset by better targeting of the product to families who were more likely to use it. Additionally, there was no evidence that higher offer prices screened out poorer or less educated households.

Researchers are partnering with Bridge International Academies to evaluate the impact of an SMS-based information provision program on students’ learning outcomes in Kenya.
