Identity-Driven Cooperation versus Competition
扩展身份经济学，探讨技术变革如何通过影响市场与非市场活动，重塑社会身份，加剧个体主义与地位竞争，减少关怀行为，进而影响社会福利。
This paper seeks to extend the domain of identity economics by exploring motivational foundations of in-group cooperation and out-group competition. On this basis, we explore the reflexive interaction between individual economic decisions and social identities in response to technological change in market economies. Our analysis explores how technological change falling on marketable goods and services, rather than non-market caring relationships, leads to a restructuring of identities, which increases the scope of individualism and promotes positional competition at the expense of caring activities. Since positional competition generates negative externalities while caring activities create positive ones, these developments have important welfare implications.
