We revisit the group size paradox in a model where two groups of different sizes compete for a prize exhibiting a varying degree of rivalry and where group effort is given by a CES function of individual e¤orts. We show that the larger group can be more successful than the smaller group if the degree of complementarity is sufficiently high relative to the degree of rivalry of the prize.
