For the class of contests where players’ state dependent cost of effort is multiplicative, we show that if the players’ Arrow-Pratt measure of relative risk aversion is increasing (decreasing), then the value of public information is positive (negative). Moreover, if players’ cost of effort (value) is state independent, then players’ effort decreases (increases) with the level of information.
