Researchers conducted a randomized evaluation to look at the effect of private connections in a setting where most households already had access to high-quality water through public taps. They found that households had a high willingness to pay for piped water, and while home water connection had no impact on waterborne illness, households' self-reported happiness improved substantially.

In Indonesia, researchers conducted a randomized evaluation with seaweed farmers to observe both the impact of participating in a program that determined optimal seaweed production methods and receiving summarized results of the program on the adoption of optimal farming inputs. They find that simply participating and observing outcomes in the program did not change key input choices in the production of seaweed. Instead, farmers changed their practices only after they were presented with summaries on results from the program.

Researchers partnered with SKS Microfinance to measure the impact of bundling a health insurance product with microloan renewals on health insurance take-up, and health care use and spending. They found that the requirement to purchase health insurance substantially reduced microcredit clients’ loan renewal rates, meaning that people were willing to give up credit to avoid buying insurance.

Researchers examined the impact of an initiative to promote savings, through financial incentives, reminders, and messaging, on the savings behavior of the urban poor in Peru. Preliminary results found that the initiative increased the probability that clients reached their savings goals; negatively framed messages appear to be more effective than positive messages in getting people to save.

Researchers are examining the impact of offering health insurance through a microfinance institution on clients’ health behaviors and health outcomes, as well as on the institution’s profit, client retention, and default rates.

Researchers tested the assumption of price inelastic demand using a randomized evaluation in South Africa. The results suggest that the demand curves were downward sloping, and steeper for price increases relative to the lender’s standard rates. Researchers also found that loan size was far more responsive to changes in loan maturity than to changes in interest rates.

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.
