SSI for Disabled Immigrants: Why Do Ethnic Networks Matter?
研究发现，居住在大量同族裔人群中的移民更可能获得残疾补充保障收入，尤其在那些高领取率的移民群体中。网络效应可能促使轻微残疾者申请，但并非源于严重欺诈。
Immigrants residing among many coethnics are especially likely to receive SSI for a disability when they belong to high SSI take-up immigrant groups. After showing that this relationship cannot be fully explained by differences in health, we consider the likely sources of these network effects by separately examining their role in the decision to apply for SSI and, conditional on applying, their role in determining who ultimately receives benefits. Our results suggest that networks may increase the probability of applying for SSI despite minor disabilities, but it is unlikely that network effects are driven by egregious lies on applications.
