In South Africa, researchers evaluated whether people have enough information to identify reliable borrowers among their peers and if they can help enforce loan repayment. They found that when given incentives, peers were not effective at screening for creditworthiness, but they were effective at enforcing peer repayment and reducing default.

In Sierra Leone, researchers evaluated the effect of publicly-screened debates during the run-up to parliamentary elections. Debates impacted voters’ political knowledge and voting decisions, and also caused candidates to invest more in their constituencies, both during the campaign and one year later.
