Workers without social connections may be disadvantaged in the labor market because employers favor applicants who have been referred. Researchers tested three interventions in an online labor market to investigate why employers are more likely to hire referred workers. First, referrals provide a signal that workers will perform well and have lower turnover. Referred workers outperformed and had lower churn than non-referred workers with the same observable characteristics. This is true even at companies to which they were not referred. Second, being referred makes workers more productive. Referred workers were particularly productive when they work with their referrers. However, workers’ concerns about their reputation with their referrer or their referrer’s position at the firm did not lead workers to exert more effort.

Health education campaigns are often seen as a way to promote healthy behaviors and encourage the adoption of inexpensive life-saving and life-improving technologies. Researchers evaluated three health education campaigns for parents that aimed to reduce iron-deficiency anemia among primary school students in rural China. None of the campaigns had an effect on hemoglobin levels or anemia. In contrast, providing students daily multivitamin supplements increased blood hemoglobin levels, although it did not improve them enough to reduce anemia rates.

Researchers partnered with Chile’s national pension authority to evaluate the effect of personalized versus generic information, delivered via self-service kiosks at government offices, on long-term savings. People who received personalized information increased their voluntary contributions in the first year, but the impacts faded over time.

Researchers evaluated the impact on educational outcomes of providing enhanced vision services to low-income elementary school children. Providing vision screening and free eyeglasses significantly increased achievement in two of the three districts studied, while screening without the provision of free eyeglasses had no effect.

The Government of Zambia partnered with researchers to test the effect of two different recruitment strategies for a newly created healthcare position, the Community Health Assistant (CHA). One strategy emphasized career opportunities and the other emphasized the contributions one could make in the community. The evaluation found that emphasizing opportunities for career advancement led to the selection of CHAs who were more qualified, had similar community service motivation, performed better on the job, and significantly improved health practices and outcomes in their communities.

Researchers are evaluating the impact of a digital school fee loan, with and without a direct repayment incentive, on repayment rates, households’ well-being, and students’ educational outcomes.

Researchers evaluated the impact of a program addressing constraints related to hygiene infrastructure and access to sanitary products while addressing social stigma around menstruation, on girls’ learning and psychosocial well-being in Madagascar. The program led to improvements in academic learning outcomes and anxiety. Reduction in stigma and improvements in observed hygiene behaviors were larger in schools with peer leaders who were identified, trained, and coached to address these harmful social norms.

Researchers evaluated the impact of informing middle school teachers in Italy about their implicit stereotypes towards immigrant students on end-of-year grading. Both math and literature teachers eligible to receive feedback before the end-of-the-year grading gave higher grades to immigrant students.

Researchers are conducting a randomized evaluation to study the effect of changing legal penalties, along with citizens’ beliefs about these penalties, on corruption and lawbreaking in India.

Researchers studied the impact of providing personalized and generic information about potential savings via letters and e-mails on enrollee health plan choices.

Researchers are partnering with Bridge International Academies to evaluate the impact of daily quizzing on students’ learning outcomes in Kenya.

In rural Uganda, researchers evaluated whether videos encouraging communities to speak out against violence against women (VAW) could change behavior, attitudes, and norms. Women exposed to the videos were more willing to report VAW to authorities. More broadly, women in villages where the videos were screened experienced less VAW in their household.

Researchers evaluated the impacts of increased exposure to financial markets on participants’ financial literacy and investment behavior in Israel, and found it reduced the gender gap in financial literacy and confidence. They found that engaging in financial markets increased participants' understanding of basic financial concepts, and reduced the gender gap in financial literacy, self-assessed financial knowledge, and subsequent stock investment.
