Researchers evaluated the long-run effects of temporary contact between individuals from different regions during military service on interregional attitudes and national identity sentiments among former Spanish male conscripts. Overall, conscription outside of one’s region of origin led to positive and long-lasting effects on interregional sentiments, and increased the sense of national identity among conscripts from regions with strong secessionists movements.

Researchers evaluated whether providing low-stakes diagnostic tests and feedback to teachers led to improved student learning outcomes in India. They found that teachers in intervention schools exerted more effort when observed in the classroom but students in these schools performed no better on independently-administered tests than students in schools that did not receive the program.

Researchers evaluated the impact of access to a package of free dental services on employment levels for urban residents of Santiago, Chile. Results found that participants with access to these services had better dental health, and that self-esteem and short-term employment increased among women, particularly those who had previously been missing front teeth or with lower levels of self-esteem.

Researchers evaluated whether an alternative teacher incentive scheme, providing rewards based on the performance of all students, could help reduce dropout and improve student math learning. Introducing the pay-for-percentile incentive scheme reduced overall student dropout rates. However, these reductions were driven almost entirely by students at intervention schools with math textbooks. Among schools with math books, the incentive scheme also improved the math achievement for higher performing students.

In Niger, researchers evaluated the impact of a training program for input distributors (agro-dealers) on smallholder access to and use of agricultural inputs. Researchers found that trainings for agro-dealers combined with a demonstration plot increased the share of farmers adopting improved seeds, but did not increase the quantity used to have an impact on agricultural output.

Researchers conducted a randomized evaluation to test the impact of providing recently unemployed individuals informational brochures about job search strategies that motivated an active search on their labor market outcomes. Providing informational brochures improved the employment and earnings of job seekers who exhibited an increased risk of long-term unemployment but had no measurable effects on the general population.

Researchers conducted a randomized evaluation to test the impact of life skills training and mentoring on dropout rates and non-cognitive skills among girls in India. Their evidence suggests that the intervention is successful in developing stronger life skills including increased agency, more equitable gender norms, and stronger socio-emotional support.

In partnership with Melchia Investments, a private Ghanaian technology company, researchers are conducting a pilot randomized evaluation to identify the effectiveness of a new tax collection technology in increasing property tax revenues for local governments.

Researchers are evaluating the impact of providing different types of information about the health risks of Covid-19 on individuals’ risky behavior among diabetic and hypertensive individuals in Tamil Nadu, India, with special attention to de-biasing over-optimism about personal health risk.

Researchers studied the impact of the gender of communicators on the effects of a program to train farmers to communicate information on agricultural technology to other farmers. While there was no gender gap in communicators’ ability to acquire, retain, and use the information about the technology, other farmers were less willing to learn from female communicators. In spite of this, other farmers learned just as much about the technology and experienced similar farm yields when the communicator role was reserved for women.

Researchers evaluated the effects of introducing price increases during peak periods and also real-time information about electricity usage to residential customers in the United States. Households that received feedback about usage reduced consumption and individuals were more responsive to pricing events that happened with more advance notice.

In Tanzania, researchers are conducting a randomized evaluation to test the impact of factory employment and different compensation schemes on gender differences in labor market outcomes, taste for competition, and views on social and gender norms.

Re searchers used a randomized evaluation to measure the impact of providing mobile calling credits to low-income adults on well-being outcomes in Ghana. Overall, the mobile credit intervention increased the ability for individuals to meet unexpected communication needs, particularly when delivered in installments, leading to meaningful improvements in mental health and modest decreases to domestic violence.

Researchers randomly provided more or less cash to garment-making firm owners in Ghana before a bargaining game to evaluate the impact of endowment on the negotiated sale price of a good. Owners of garment-making microenterprises with lower household liquidity agreed to lower sale prices during the bargaining process, suggesting that the prior wealth of microentrepreneurs who participate in bargaining may impact how much they are able to earn.

The researcher evaluated the impact of a sexual harassment training on the incidence of sexual harassment, opposite sex relationships, and attitudes and beliefs towards sexual harassment in India. Overall, the training reduced extreme forms of sexual harassment in the short run and intermediate forms of harassment in the long run, likely by changing men’s beliefs about others' attitudes to sexual harassment. The training also reduced opposite sex romantic relationships between classmates.
