Transmission of information within transnational social networks: a field experiment
通过实地实验，研究近期移民如何向母国社会网络成员传递风险决策信息，发现家人建议和朋友决策显著影响母国个体的风险选择。
Abstract Several studies have shown a relationship between the stocks of migrants and country-level investment in the home country; however the mechanism through which this relationship operates is still unexplored. We use a field experiment in which participants who are recent immigrants send information about risky decisions to others in their social network in their home country. The results demonstrate how this information influences decisions in the home country. We find that the advice given by family members and decisions made by friends significantly affects an individual’s risky decision-making.
