Information sharing in private value lottery contest

Author

Listed:
  • Wu, Zenan
  • Zheng, Jie

Abstract

We investigate players’ incentives to disclose information on their private valuations of the prize ahead of a rent-seeking contest: Information sharing arises in equilibrium if types are concentrated enough, whereas sharing information is strictly dominated if types are sufficiently dispersed.
