Researchers evaluated the impact of a door-to-door deposit-collecting service, which regularly collected funds from clients’ homes to be deposited at a local bank, on clients’ savings. Results demonstrated that clients who lived farther from a bank were more likely to take up the service, and clients who took up the service significantly increased their savings.

This study measured the effect of receiving free subscriptions to either a liberal or conservative-leaning newspaper on voters’ political knowledge and opinions in the United States. Results demonstrated that neither subscription had an impact on voters' political knowledge, but that both subscriptions caused voters to increase their support for the Democratic presidential candidate. This suggests that the informational effect of news exposure was stronger than the effect of the slant.

This evaluation examined the direct impact of providing small consumer loans to marginally creditworthy individuals in South Africa on their credit access, investment, and well-being, as well as the profitability of these loans for lenders. Results found approving loans for marginally creditworthy applicants did improve economic outcomes for poor households and generated profits for lenders.

Researchers measured the impact of individual-liability microcredit on marginally creditworthy applicants in the Philippines. They found that increased access to microcredit expanded borrowing and improved risk management and sharing, but it also led clients to shrink their businesses.

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 investigated the impact of the price of insecticide-treated bed nets (ITNs) on usage and demand in Kenya. Researchers found that cost-sharing considerably dampened demand, and those who were left out under a cost-sharing scheme had very high usage rates when they could access the product for free. Because there are social health benefits from achieving a certain ITN coverage rate, the results suggest that free distribution of ITNs is both more effective and cost-effective than cost-sharing.

Researchers studied the policy consequences of mandated representation of female policymakers by determining whether there was any difference in the provision of social services between male- and female-led village councils. Results suggest that reservations for female leaders affected policy decisions in ways that seemed to better reflect women’s preferences.

Researchers conducted a randomized evaluation to test the impact of offering interest-paying mobile money saving accounts to farmers, and in some cases farmers’ friends, on their financial behavior such as agricultural investment. Providing farmers access to interest-bearing mobile savings accounts increased both the amount of money they saved using these accounts and the likelihood they invested in fertilizer, while providing farmer’s closest farming friends the same incentivized mobile money accounts did not increase savings.

International remittances are an important financial tool for many developing countries, and many organizations offer financial products or financial education services to help families manage the remittances they receive. Researchers provided families with financial products and financial education in the Philippines to test whether the two services influenced each other.

Fertilizer use has been promoted to boost agricultural productivity and increase farmers’ yields and income. Researchers conducted a randomized evaluation among rice farmers in Bangladesh to evaluate the impact of providing leaf color charts and basic training on the quantity and timing of fertilizer use and crop yields. Fertilizer use declined while yield moderately increased for farmers.

In Zambia, researchers examined the impact of access to seasonal credit on farming households’ consumption, labor allocation, and agricultural output. The results suggest that access to food and cash loans during the lean season increased agricultural output and consumption, decreased off-farm labor, and increased local wages.
