Researchers tested two features of these contracts, repayment frequency and the time of the first repayment, to determine if characteristics of the loan contract affect borrowers’ repayment behavior and the types of investments they make. They found that less frequent repayments did not increase defaults. A two-month grace period before beginning repayment raised the default rate slightly but allowed entrepreneurs to invest more in their businesses, resulting in long term economic gains.

Researchers offered two days of business training and assistance in identifying a medium-term financial goal to a random sample of women of different castes and religions in India. A random sub-sample of women were invited to attend the training with a friend. Women trained with a friend doubled their demand for loans and expanded their business activity, resulting in higher household income. This impact was stronger among women from religious or caste groups with social norms that restrict female mobility.

In order to examine how voter preferences vary with information about the relevance of ethnicity and politician quality, researchers randomly assigned polling stations during the 2007 Uttar Pradesh elections to two information campaigns, one calling for people not to vote for a party simply for representing their caste and one calling them not to vote for corrupt candidates. The caste campaign not only reduced the likelihood that an individual would vote for a party representing their caste but also increased voter turnout and reduced the voter share of candidates facing heinous criminal charges.

Researchers evaluated the impact of a reform to the pollution audit system in India, making auditors more independent, on the truthfulness of their reporting and the behavior of the firms they audited. Increasing their independence made them more likely to report the truth about industrial plants’ pollution levels.

Researchers tested how demand for weather insurance responded to different marketing schemes and price discounts. They found that demand was very price sensitive, but that poor understanding of the product, distrust of insurance agents, and liquidity constraints also limited take-up.

In three related evaluations in India, researchers introduced an early childhood reading and comprehension program (Shishuvachan) in different contexts—integrated into first-grade classes in Mumbai public schools, implemented in preschools that were specifically designed to implement this program, and integrated into established preschool classes—in order to measure its impact on early literacy rates. Results show that the Shishuvachan program was very effective in improving students' reading skills.

Researchers conducted a randomized evaluation to measure the impact of a crop price awareness program on reducing price uncertainty and promoting forward-looking planting decisions among farmers in India.

Researchers partnered with the Indian NGO Pratham to evaluate whether different technologies and implementation methods can increase students’ English test scores. Overall, the interventions were effective at increasing students’ knowledge of English.

Researchers worked with Bank Rakyat Indonesia and the Microfinance Innovation Center for Resources and Alternatives to measure the impact of incentives and financial education on savings account take-up. Results indicated that the financial education program was not an effective tool for promoting the use of bank accounts, but modest financial subsidies did increase the share of households that opened a formal savings account. Overall, these results suggest that take-up of formal financial services may be more easily achieved through measures designed to reduce the price of financial services, rather than through large-scale financial literacy education.

Researchers partnered with the Akshara Foundation in Bangalore, India to evaluate the impact of hiring trained librarians in primary schools on students’ academic achievement. Overall, the intervention had little effect on students' language, math, and science skills and had no impact on student attendance rates.

Researchers evaluated the effect of (a) simple text message reminders and (b) financial incentives on borrowers' loan repayment. These methods had similarly positive effects, which suggests that the text message reminders may be a more cost-effective intervention. The reminders proved particularly effective for younger borrowers.

Researchers evaluated the effect of personalized options information on seniors' plan choices. They found that people who received personalized information were more likely to change plans, resulting in an average saving of US$100 per year. This suggests that direct information delivery can decrease the difficulty of comparative research, thereby helping consumers make more informed decisions about government services.

Researchers evaluated the effect of the framing of potential investment options on people's investment in life annuities. They found that individuals were more likely to prefer an annuity when their options emphasized future consumption, rather than framing options in terms of investments. These preferences were revealed in hypothetical, but realistic, scenarios.
