Abstract

We study contests between two groups where all the players have a common value of winning. In each group one of the players has an information advantage over the other players. This player is referred to as the dominant player. We show that a group contest is equivalent to a contest between the dominant players, and, as such, the expected total effort of both groups is always the same, while their probabilities of winning as well their expected total payoff are not.
