The paper doesn’t seem to exist yet but here are slides from talk by Raj Chetty, Emmanual Saez and Lazlo Sander.  They randomly altered the incentives for referees at the Journal of Public Economics to see what it takes to get referees to give timely reports.  Some referees were offered cash.  Some were simply given shorter deadlines with no carrots.  Still others were threatened with public shame if they did not submit reports on time.  Not surprisingly the threat of humiliation caused many referees to refuse the contract altogether.  Perhaps less surprisingly, cash didn’t do much better than simply shortening the deadline.  The latter did help a bit.
