Intergenerational Mobility of Immigrants in the United States over Two Centuries
利用超过100年的父子配对数据，发现来自几乎所有国家的移民子女向上流动性高于美国本土出生者子女，且这一优势在历史上和今天相似，部分源于移民选择定居在子女前景更好的地区。
Using millions of father-son pairs spanning more than 100 years of US history, we find that children of immigrants from nearly every sending country have higher rates of upward mobility than children of the US-born. Immigrants’ advantage is similar historically and today despite dramatic shifts in sending countries and US immigration policy. Immigrants achieve this advantage in part by choosing to settle in locations that offer better prospects for their children.
