Social identities prescribe behaviors for people. We identify the marginal behavioral effect of these norms on discount rates and risk aversion by measuring how laboratory subjects' choices change when an aspect of social identity is made salient. When we make ethnic identity salient to Asian-American subjects, they make more patient choices. When we make racial identity salient to black subjects, non-immigrant blacks (but not immigrant blacks) make more patient choices. Making gender identity salient has no effect on intertemporal or risk choices.
社会身份为人们规定了行为方式。我们通过衡量当社会身份的某个方面变得突出时实验室受试者的选择如何变化,来确定这些规范对贴现率和风险厌恶的边际行为影响。当我们使亚裔美国人的种族身份变得突出时,他们会做出更有耐心的选择。当我们使黑人受试者的种族身份变得突出时,非移民黑人(而非移民黑人)会做出更有耐心的选择。使性别身份变得突出对跨期选择或风险选择没有影响。
