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.

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.
