Researchers tested whether reminders delivered via text message improved knowledge and adoption of social distancing and handwashing. They found no evidence that individuals changed their self-reported behaviors; this finding may highlight limited effectiveness of SMS-based information campaigns after the initial phase of the pandemic.

Researchers evaluated the impact of general and personalized information regarding the relationship between wood burning and indoor pollution on households’ knowledge of pollution and their pollution mitigation efforts. Both general and personalized information increased households’ awareness of pollution, but only personalized information improved households’ measured air quality.

Researchers evaluated the effects of a national apprenticeship training program on the firms that received apprentices. Firms that received apprentices increased their profits as well as employment.

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.

Researchers worked with the state government to evaluate the impact of three programs to build demand for vaccination: local immunization ambassadors, small, non-financial incentives, and tailored SMS reminders. The most effective policy option increased measles vaccination by approximately 55 percent by combining local immunization ambassadors selected by the community, incentives that increased in amount across the immunization schedule, and SMS reminders to caregivers about the next scheduled vaccine.

In France, researchers evaluated the effect of a financial independence and social integration program for young adults living in government-subsidized housing. They analyzed its impact on the young adults’ professional lives, housing situations, financial independence, and general welfare.

The researchers aim to understand the role that digital cash transfers can play as a policy tool both to increase household resilience during the pandemic and to stem the spread of the disease by increasing adherence to social distancing in Ghana.

By the time they reach primary school, disadvantaged children often lag behind their more advantaged peers in the skills and concepts of formal math. To address this issue, researchers examined the impact of math games, played in preschools and exercising early emerging, universal and intuitive numerical and spatial abilities, on children’s learning of school math in Delhi, India. They found that the games led to long-term increases in children’s intuitive math abilities. The games also bolstered children’s mastery of the spatial and numerical language used in the preschools, but they did not enhance children’s subsequent learning of primary school mathematics.

Researchers conducted a randomized evaluation to understand whether providing information about the risk of accident and methods for prevention, or incentives to install home safety measures affect take-up of a home safety adaptations program. Cost reduction incentives and information disclosures increased take-up of home safety adaptations. Providing information on the perceived risks of falling was more effective than offering home adaptations for free.

In the United States, researchers evaluated the impact of the mandatory-participation bundled payment model for hospitals and explored which hospitals were incentivized to opt in to bundled payments after the model was later made voluntary. The mandatory-participation bundled payment program produced modest reductions in Medicare claims, but the voluntary program produced smaller declines in Medicare claims than if the mandatory program had continued.

Researchers evaluated the impact of a bid training program on the business performance of local small and medium-sized firms. The bid training led firms to bid on and win more contracts, with the positive impacts concentrated on a quarter of firms.

Researchers are partnering with the Mexico City Labor Court to evaluate whether rotating court notifiers across areas and casefiles can reduce incidences of bribery, increase the notification rates, and improve the functioning of labor courts.

Researchers evaluated the impact of exposure to and incentives to consume discordant media on political attitudes and behaviors in Turkey. Participants changed their media consumption habits, trusted discordant media sources more, and had less polarized attitudes towards the government, but did not change how much they trusted people with opposing political views.

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.
