The Last Will Be First, and the First Last: Segregation in Societies With Relative Payoff Concerns
研究了生产率不同的个体如何形成联盟，发现平等主义和个人主义社会中都会出现按生产率相邻者结盟的隔离现象，且被排除在外的分别是生产率最低和最高者。
Abstract This article studies coalition formation among individuals who differ in productivity. We consider egalitarian societies in which coalitions split their surplus equally and individualistic societies in which coalitions split their surplus according to productivity. Preferences of coalition members depend on their material pay-offs, but are also influenced by relative pay-off concerns. The stable partitions in both egalitarian and individualistic societies are segregated, i.e., individuals with adjacent productivities form coalitions. If some individuals are not part of a productive coalition, then these are the least productive ones for egalitarian societies and the most productive ones for individualistic societies.
