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.

Credit-building loan products (CBLs) have begun to proliferate in the U.S. marketplace, but there is little evidence on the effects of these products on consumers and lenders. IPA and RAND worked with researchers to evaluate the impacts of a CBL offered at a credit union in Missouri, both alone and coupled with financial education. While on average CBLs did not affect credit scores, they increased the likelihood of having a credit score and improved credit scores for individuals who did not have loans at the beginning of the study

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.

Researchers studied the short- and long-run effects of these reports on electricity use and found that reports reduced energy consumption by about 2 percent across twelve utilities. The reports had the strongest effect in the short-run, but the program had enduring effects among households that were dropped from the program after two years.

Researchers are testing the impact that stress-tolerant seeds, which have better yields than conventional varieties under weather shocks, affect landless laborers.

During periods of high electricity use that strain the grid, electricity customers do not have any reason to conserve because they pay a fixed price per kilowatt hour of power. In this study, the researcher evaluated the impact on electricity usage of a real-time pricing scheme, which charges households different prices throughout the day based on fluctuating wholesale costs. Households charged according to real-time pricing consumed less electricity in response to higher prices, primarily due to lower consumption during peak times.

Researchers conducted a randomized evaluation to test whether organizing short learning sessions for villagers about early adopters’ use of a flood-tolerant rice seed variety, Swarna-Sub1, impacted other farmers’ adoption of it. These “farmer field days” were a cost-effective strategy to improve farmers’ learning about Swarna-Sub1 and increased their take-up of Swarna-Sub1 in the next planting season by 40 percent.

Researchers worked with a large nationwide retailer in the United States to test whether sharing information, and providing subsidies and sales incentives had an effect on the demand for energy efficient water heaters. Results showed that information alone did not increase demand, and a $100 rebate or the combination of a $25 sales incentives and a $100 rebate significantly increased purchases of the water heaters. In this context, providing more information alone was not an effective way of increasing demand for energy efficient durable goods.

A study on parents’ demand for conditionality in a Brazilian cash transfer program revealed that parents are willing to pay to for the conditionality in order to monitor their children’s school attendance.

Researchers conducted a randomized evaluation of the ways in which information dissemination within social networks affected farmers’ adoption of a weather insurance product in rural China. Results suggest that social networks had a significantly positive effect on insurance take-up, driven by the diffusion of knowledge about insurance. These effects were larger when people who were the first to receive financial education were more central to the social network.

In Argentina, a researcher evaluated whether informing students of their potential could be a cost-effective way to increase motivation and improve educational outcomes among secondary school students. They found that the intervention did not impact students’ perceptions of the difficulty of school tasks, school climate, academic performance, or future education plans.
