In recent years, a growing literature emerged studying the role of identity in economics. Yet, mainstream economists and other social scientists still eye identity economics with suspicion. This article illustrates the underlying assumptions of identity economics, gaps in the literature, as well as existing tools and research in other domains of economic theory that help to close these gaps, while demonstrating that identity economics is able to provide sophisticated approaches and additional findings that support transdisciplinary research on the topic. In order to demonstrate how these tools can be used to study the complex social systems in which identity, preferences, and institutions co-evolve, I develop a number of simple analytical models and elaborate on their implications, while keeping technicalities to a minimum. In addition, I show how findings in behavioural economics apply to identity economics and prove insightful for our understanding of the complex interdependencies between identity and group formation.

走向更好的社会行为经济模型？身份经济学

近年来，越来越多的文献研究身份在经济学中的作用。然而，主流经济学家和其他社会科学家仍然怀疑地看待身份经济学。本文阐述了身份经济学的基本假设、文献中的差距以及有助于缩小这些差距的其他经济理论领域的现有工具和研究，同时证明身份经济学能够提供复杂的方法和其他发现支持关于该主题的跨学科研究。为了展示如何使用这些工具来研究身份、偏好和制度共同进化的复杂社会系统，我开发了许多简单的分析模型并详细阐述了它们的含义，同时将技术性保持在最低限度。此外，
