Experiment.

We conducted an embedded experiment when we surveyed donors to see what types of prompts (peer effects, a matching incentive, or both) might incentivize them to use the PaP system to pay school fees by an earlier deadline. Donor attendance at registration events was almost 100% and thus (a) independent of treatment. However, (b) donors overall strongly preferred to use matching funds for a computer or library, not general funds or improvements to school grounds. At the transaction level, numbers are again too small to assess statistical differences, but seem independent of (c) experimental treatment or (d) a donor’s particular preference for how to use matching funds.
