Efficient voting with penalties

Maksymilian Kwiek

Games and Economic Behavior, 2017, vol. 104, issue C, 468-485

Abstract: Simple majority does not reflect the intensity of voters' preferences. This paper presents an efficient collective choice mechanism with two alternatives when the designer may use non-transferable punishments to persuade agents to reveal their private information. The designer faces a dilemma – a punishment may induce a more correct choice, but its cost is socially wasteful. The efficient mechanism is a weighted majority. Weight of each individual is known ex ante and no punishments are applied if preferences are relatively homogeneous. Eliciting types through punishments in order to construct type-specific weights should occur if preference intensity is relatively heterogeneous.
