The existence of a strong link between socio-economic background and individual preferences has been documented among both children and grown-ups. Here, we study whether such a correlation persists even in a highly homogeneous population of young adults: university students. Our findings indicate that participants living in an area characterized by a high socio-economic environment tend to trust more and are more inclined to reciprocate higher levels of trust, as compared to those coming from less wealthy neighborhoods. This behavioral difference is, at least in part, driven by heterogeneities in beliefs: subjects from the most affluent part of the city have more optimistic expectations on their counterpart’s trustworthiness than those living in a lower socio-economic environment. By contrast, no significant differences emerge in other preferences: generosity, risk attitudes, and time preferences. Finally, we do not find any systematic evidence of out-group discrimination based on neighborhood identity.

儿童和成年人之间都有社会经济背景和个人偏好之间的紧密联系。在这里，我们研究了即使在高度同质的年轻人群体（大学生）中，这种相关性是否仍然存在。我们的研究结果表明，与来自较不富裕社区的参与者相比，生活在具有较高社会经济环境的地区的参与者倾向于更多地信任，并且更倾向于回报更高的信任度。这种行为差异至少部分是由于信仰的异质性所致：与生活在较低社会经济环境中的人相比，来自城市最富裕地区的人们对同伴的信任度抱有更为乐观的期望。相比之下，其他偏好没有明显差异：慷慨，风险态度和时间偏好。最后，我们找不到基于邻里身份的群体外歧视的任何系统证据。
