Immigration and Social Mobility

At the National Bureau of Economic Research, Ran Abramitzky and colleagues have a paper titled "Intergenerational Mobility of Immigrants in the US over Two Centuries." The abstract:

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. In the past, this advantage can be explained by immigrants moving to areas with better prospects for their children and by “underplacement” of the first generation in the income distribution. These findings are consistent with the “American Dream” view that even poorer immigrants can improve their children’s prospects.
