题目: “经济学系列讲座”第47期 Endogenous Information Acquisition and Norm Formation
主讲人：Marie Claire Villeval法国国家科学研究中心经济学教授，经济科学协会(ESA)主席、Management Science部门主编
We investigate whether the ability of individuals to select their source of information affects the influence of social information on behavior and on empirical and normative beliefs in the ethical domain. In a large scale (N=1945) online lying game, we vary across treatments whether individuals can access empirical or normative information from others, and the presence of group identity in terms of political affiliation.
We show that information search is motivated self-servingly, as a majority of individuals manage to consume more lenient information. This bias depends on whether own party is or not the source of lenient information. Selecting a more lenient source of normative information increases the willingness to lie, while empirical information influences empirical beliefs but much less behavior. Normative beliefs are influenced neither by empirical or normative information. A follow-up experiment (N=2414) reveals that assigning the source of information exogenously weakens the influence of social information, with little effect of polarization.
Key words: Social Norms, Information Acquisition, Peer Effects, Group Identity, Dishonesty
