We study how changes in the information available to the players of a symmetric common-value Tullock contest with incomplete information affect their payoffs and their incentives to exert effort. For the class of contests where players' state dependent cost of effort is multiplicative, we show...

We show that under standard assumptions a Tullock contest with asymmetric information has a pure strategy Bayesian equilibrium. Moreover, two-player common-value Tullock contests in which one of the players has an information advantage have a unique equilibrium. In equilibrium both players exert...
