Migration, Friendship Ties, and Cultural Assimilation
利用德国社会经济面板数据，研究发现有德国朋友的移民在经济关切、政治兴趣和政策态度上更接近本地人，而就业、居住时间、生育、搬家及在德国接受教育是建立友谊的关键因素。
Abstract We study immigrant assimilation by analyzing whether friendship with natives is a measure of cultural assimilation, and by investigating the formation of social ties. Using the German Socio‐Economic Panel, we find that immigrants with a German friend are more similar to natives than those without German friends, along several important dimensions, including concerns about the economy, an interest in politics, and a host of policy issues. Turning to friendship acquisition, we find that becoming employed, time spent in the host country, the birth of a child, residential mobility, and additional education acquired in the host country are significant drivers of social network variation.
