THE ENHANCING EFFECT OF INTERGROUP COMPETITION ON GROUP-PERFORMANCE

This paper examines the effect of intergroup competition on intragroup cooperation. Three experiments are reviewed. The first experiment establishes that intergroup competition can effectively increase intragroup cooperation in a laboratory setting where symmetric players make binary decisions in one-shot dilemma games. The second experiment shows that this constructive effect of intergroup competition is generalizable to a real-life setting in which asymmetric players make continuous decisions in an ongoing interaction. The third experiment demonstrates that the increase in intragroup cooperation can be accounted for at least in part by motivational, rather than structural, effects of the intergroup competition. Theoretical and practical issues concerning the applications of these findings are discussed
