We consider collective contests with group-specific minimum shares, which we call group-specific "norms" of competitiveness. The minimum shares bound the incentive schemes available to a group. We fully characterize how group sizes interact with such norms. We show that the smaller group is generally "aggressive," adopting the norm sharing rule, which helps generate maximal intra-group competition. On the other hand, the larger group is often "docile," exceeding the norm sharing rule, which softens intra-group competition. We also examine how group welfare relates to group sizes and the norm sharing rules. We identify when the larger group fares worse in the contest, a phenomenon known as Group Size Paradox in the literature.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
