Truthfulness Compensation in Mechanism Design
Community peer evaluations suffer from strategic misreporting when participants attempt to direct resources toward family and friends. Without an explicit counter-incentive for accuracy, social ties dominate survey responses, preventing lenders from acquiring honest information.
Picture this
Imagine a witness in court who is tempted to lie to protect a friend, but is offered a small reward if testimony matches verifiable facts. By offering peer evaluators a modest financial bonus tied to the objective accuracy of predictions, evaluators weigh the immediate cash reward for honesty against the social temptation to favor friends, restoring truthful information flow.
What the evidence says
Small monetary payments for accuracy doubled reporting accuracy under no-stakes conditions and improved reporting accuracy by over 100% under high-stakes conditions at an added cost of only INR 40 (US$0.70) per loan.
- Who
- 1,345 households in 274 peer groups of five microentrepreneurs in Amravati, Maharashtra, India [5, 6].
- How
- Randomized evaluation assigning peer groups to receive accuracy-calibrated compensation of INR 100 (US$1.70, equivalent to two-thirds of average daily wage) versus a lump-sum compensation regardless of accuracy [12, 13].
What to do
Offer microentrepreneurs small, accuracy-calibrated monetary incentives when completing peer evaluation surveys to ensure truthful data collection.
From the source
"Conversely, the monetary payments substantially improved the accuracy of reports by over 100 percent."
