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 evaluated two types of reward contracts—one that rewarded providers for increased use of inputs and one that rewarded providers for improved health outputs—among rural obstetric care providers in India. They found that both contracts reduced post-partum hemorrhage by 20-23 percent.

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 of enabling Filipino migrants to label remittances for education on the amount of money they sent home. Labeling remittances as funds to be used for education raised the amount of money migrants sent home substantially (over 15 percent).

In Tanore district of Bangladesh, researchers tested the impact of providing external subsidies for sanitation projects on the behavior of local leaders and, subsequently, on constituents’ perception of their performance. They found that while constituents credited leaders for the sanitation program when the funding source was unknown, they did not credit local leaders when funding information was made transparent.

Researchers worked with First Valley Bank in the Philippines to evaluate the impact of varying the interest rate and account ownership requirements on demand for commitment savings accounts. While savings account take-up was 23 percent, neither the interest rates nor the ownership requirements affected individuals’ demand for accounts.

Improved crop varieties have the potential to produce higher yields than traditional varieties, but rural farmers often do not have the knowledge to properly grow these crops. Researchers seek to understand how providing different amounts of training on how to cultivate NERICA-3, a high-yield but difficult-to-grow rice variety, affects rice yields, nutrition, and health among rural households in Sierra Leone.

Researchers evaluated the impact of photographic monitoring technology on aggregation fraud and perceptions of government legitimacy during the 2010 parliamentary elections in Afghanistan. The announcement of a new monitoring technology reduced both theft of election materials and vote counts for politically connected candidates and increased perceptions of government legitimacy.

Energy-efficient technologies, such as compact fluorescent lightbulbs (CFLs), have the potential to save consumers money, but their adoption remains low. Researchers evaluated the impact of information and price on demand for CFLs in two contexts: an online survey platform and a typical retail setting. Information and subsidies increased consumers’ willingness to purchase CFLs. Researchers estimate that CFL subsidies and information may be more beneficial than bans on incandescent lightbulbs.
