Researchers partnered with the Honduran government to evaluate the impact of replacing textbooks with laptops on student learning. Using laptops resulted in no change in learning outcomes, suggesting that laptops could be a cost-effective substitute to textbooks if they can replace enough textbooks.

Researchers partnered with a large Indonesian Islamic bank to evaluate the impact of sending moral appeals in reminder text messages to late-paying credit card holders. Messages stating that non-repayment of debts by someone who is able to repay is an injustice increased the number of clients meeting minimum payments, proving more effective than substantial financial incentives for repayment.

In partnership with a mobile network operator launching a new phone-based savings account, researchers evaluated the role of defaults and financial incentives on savings decisions. Two months after the launch of the phone-based savings account, the company’s employees randomly assigned a default contribution rate of 5 percent were 40 percentage points more likely to contribute to the account than employees assigned a default contribution rate of 0 percent.

Researchers conducted a randomized evaluation in Ethiopia, Tanzania, and Zambia to measure whether generating social connections between manufacturing firm managers could lead to the diffusion and adoption of best business practices. These social interactions led to the spread of best practices related to business formalization, but did not increase the implementation of other practices that may boost business productivity.

Researchers partnered with the Bavarian State Opera House to conduct a randomized evaluation to test the impact of different fundraising methods on the giving behavior of aristocrats and corporations. They found that aristocrats were more responsive than other donor types but corporations gave the largest donations across all treatment groups.

Researchers investigated the impact of a new product that allowed Kenyans to invest small amounts of money in low-risk, high-return infrastructure bonds using their mobile phones. However, lack of awareness and low product take-up, triggered by logistical issues during implementation and a pending general election, ultimately led researchers to discontinue the evaluation.

Researchers in Indonesia compared the effectiveness of two methods of identifying the low-income households: a community method where villagers ranked households according to perceived wealth, and a proxy-means test which relied on measures of consumption and assets. The community methods of selecting who qualified for the cash transfer program were less accurate than proxy-means tests overall, but they greatly improved local satisfaction and better matched the low-income individual's own concept of poverty.

Employers often rely on subjective performance evaluations by supervisors to gauge the performance of workers–particularly in the public sector, where civil servants’ work performance is hard to measure. However, relying on the opinions of local supervisors could cause subordinates to prioritize pleasing their supervisors rather than focusing on productive tasks and work responsibilities. Researchers conducted a randomized evaluation testing the impact of two alternative subjective performance evaluation schemes on subordinates’ work performance.

In Pakistan, researchers are evaluating the impact of using mobile phones to directly connect politicians with voters and give voters the opportunity to provide real-time feedback to their elected representatives.

Researchers are conducting a lab-in-the-field study to measure the impact of a community-driven development program in Bangladesh on participants’ preferences and values about fairness, equity, civic engagement, and participatory decision-making.

Following the implementation of a policy mandating lower-caste representation in some local village councils in India, researchers evaluated how lower-caste presidents invested in and distributed goods. They found that disadvantaged lower-caste groups received more public goods in councils with an elected leader from their own group.

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.

Working with a large bank in Indonesia that markets platinum credit cards to high-income customers, researchers designed a series of randomized evaluations to understand the demand for status goods. Overall, researchers found that a substantial part of the demand for the platinum card is explained by the desire to own the prestigious card itself, beyond the tangible benefits and services it comes with.
