Researchers evaluated the impact of several informational interventions with different modes of delivery and customization levels on high school choice outcomes among middle school students in New York City. All interventions made students less likely to rank a low graduation rate high school as their first choice and less likely to apply to any low graduation rate schools

Leveraging the increasingly widespread use of social media, researchers conducted a large-scale randomized evaluation to test the direct and indirect impact on electoral accountability of a nonpartisan information campaign delivered via Facebook ads during the 2018 Mexican municipal elections. Incumbent parties with negligible corruption levels saw their vote share increase by 6-7 percentage points in localities targeted by the Facebook ads.

In the United States, researchers evaluated the impact of the mandatory-participation bundled payment model for hospitals and explored which hospitals were incentivized to opt in to bundled payments after the model was later made voluntary. The mandatory-participation bundled payment program produced modest reductions in Medicare claims, but the voluntary program produced smaller declines in Medicare claims than if the mandatory program had continued.

Researchers conducted a randomized evaluation in East Java, Indonesia to investigate the impact of the level and transparency of financial incentives on the take-up of these new banking services. They found that larger incentives caused an increase in take-up, but only when the incentives were not publicized among the community. When incentives are made public, higher incentives instead have no effect on take-up, despite greater agent effort.
