Information and immigrant settlement
研究随机分配的信息干预（2.5小时行前培训及手册）对菲律宾新移民在美国定居的影响，发现虽不影响就业和福祉，但显著减少了移民的社会网络连接，表明信息与社会网络存在替代关系。
We study a randomly-assigned program providing information on U.S. settlement for new Filipino immigrants. The intervention, a 2.5-hour pre-departure training and an accompanying paper handbook, has no effect on employment, settlement, and subjective wellbeing, but leads immigrants to acquire substantially fewer social network connections. We rationalize these findings with a simple model, showing that information and social network links are substitutes under reasonable assumptions. Consistent with the model, the treatment reduces social network links more when costs of acquiring network links are lower. Offsetting reductions in the acquisition of social network connections can hence reduce the effectiveness of information interventions.
