Social Identity and Preferences
通过实验让亚裔美国人和非裔美国人的社会身份变得突出，发现这会影响他们的耐心程度（即时间贴现率），但对风险偏好无影响；性别身份突出则无效果。
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.
