Economist: When national governments dispense funds to local governments to spend on local projects, any local government can receive a greater proportion of government funds by creating more local projects than other local governments create on average.
Proposition
An incentive structure rewards individual participants based on their performance relative to other participants. Each participant's rational response is to do more of the rewarded activity, beyond what they would otherwise do, in order to capture more of the reward. The aggregate result is that everyone overdoes the activity, leading to a worse collective outcome than if no incentive existed.
Evaluate
The economist describes a competitive incentive that drives participants to take more of an action than is collectively optimal — projects funded externally, where each locality gets more by doing more than other localities — and the systemic outcome is greater overall spending and taxation across the system. The right answer should mirror this dynamic: an incentive based on relative performance, individuals each ramp up their activity, leading to a worse collective outcome.
Goal
Find an answer where individuals respond to relative-performance incentives by escalating an action beyond what's collectively beneficial, producing a worse aggregate outcome.
