Researchers examined the informational, behavioral, and monetary drivers behind takeup of residential energy efficiency audits and subsequent investments in Wisconsin. While receipt of promotional letters and subsidies did induce higher rates of audit participation, overall takeup and investment in energy efficient home solutions remained low and realized energy savings fell short of predicted models.

Researchers evaluated the effects of a free health insurance policy and UCTs of the same value on the economic, health, and psychological outcomes of informal workers in Kenya. Participants who received health insurance self-reported reduced stress and had lower cortisol levels; UCTs led to fewer children in the household being sick and reduced overall hospitalizations in the household. Neither intervention had meaningful impacts on economic outcomes or other metrics of health and healthcare utilization.

Researchers partnered with two political parties in the Philippines to evaluate the effect of deliberative campaigns on voter turnout and vote shares. While deliberative town halls did not increase voter turnout, results suggest that they were effective in increasing vote shares by changing voters’ attitudes and making the party’s platform more persuasive among specific societal groups.

Researchers conducted a randomized evaluation to study the impact of a large-scale Community-Led Total Sanitation (CLTS) program in Indonesia on sanitation practices, attitudes towards open defecation, and child health. When implemented by external resource agencies instead of local governments, CLTS increased toilet construction, reduced roundworm infestations among children under five, and decreased tolerance of open defecation.

Polio is endemic in Pakistan, and vaccination campaigns often suffer when government health workers hired to administer the vaccine underperform. Researchers introduced individualized bonus contracts to health workers to evaluate the impact of time preferences on vaccine delivery and quality of service. Relative to those with random contracts, vaccinators with tailored contracts provided significantly smoother service.

Researchers introduced two programs during peak consumption hours—text messages encouraging energy conservation for the benefit of society, or price increases—to evaluate the impact of social motivation and dynamic pricing on energy conservation. Both programs led to reductions in electricity use, but the impacts of the dynamic pricing were larger and persisted for longer than the impacts of the social motivation messages.

Researchers conducted a randomized evaluation of the VIP:Voice, a digital election participation platform, to measure the impact of information and communications technologies on individuals’ political participation. Via the platform, researchers interacted with nearly 100,000 citizens, recruited citizen monitors in 38 percent of the wards of South Africa and deployed 347 citizen monitors to polling places. However, around 50 percent of participants dropped out at each subsequent, and more time-intensive, form of engagement requested via the platform.

In Peru, researchers are conducting a randomized evaluation to measure the impact of an SMS reminder campaign on the frequency of credit report checks, credit scores, total debt levels, and interest rates paid on debt.

Researchers examined the impact of race concordance (when the race of a patient matches that of their physician) and incentives on the take-up of preventive health services by Black men. Results indicate that physician race concordance significantly boosted demand for all preventive health services, and especially for more invasive tests.
