I reviewed a lot of the studies of the economic effects of immigration in LBO several years ago: Economics of immigration. Bottom line: on balance, it’s quite good. Not popular these days, so it’s more important than ever to make the point.
Just in, a new study from the San Francisco Fed. Quoting from the abstract:
Statistical analysis of state-level data shows that immigrants expand the economy’s productive capacity by stimulating investment and promoting specialization. This produces efficiency gains and boosts income per worker. At the same time, evidence is scant that immigrants diminish the employment opportunities of U.S.-born workers.
It’s too bad that most of the yahoos whipping up a nativist frenzy aren’t much into empirical evidence. But there it is.
