Today Greg Mankiw finds a paper that attempts to show what I’ve been saying all along about illegal aliens:
Using data drawn from the 1960-2000 U.S. Censuses, we find a strong correlation between immigration, black wages, black employment rates, and black incarceration rates. As immigrants disproportionately increased the supply of workers in a particular skill group, the wage of black workers in that group fell, the employment rate declined, and the incarceration rate rose.
Of course, I’d blame some of that on other disastrous Democratic policies, but I’m glad the idea’s out there.
