Consider a symmetric common-value Tullock contest with incomplete information in which the players’ cost of effort is the product of a random variable and a deterministic real function of effort, d. We show that the Arrow–Pratt curvature of d\(R_{d},\) determines the effect on equilibrium efforts and payoffs of the increased flexibility/reduced commitment that more information introduces into the contest: If \(R_{d}\) is increasing, then effort decreases (increases) with the level of information when the cost of effort (value) is independent of the state of nature. Moreover, if \(R_{d}\) is increasing (decreasing), then the value of public information is nonnegative (nonpositive).
