Professor Borjas, not exactly a fan of immigration, has often found in his research that there are negligible adverse wage impacts of new immigrants on native Americans. This is not a surprising result. Of course, in a new paper, he claims that those previous findings were due to measurement error. It could be. We can’t say. But it sure would have been nice for my brain to have seen a proponent of immigration report this kind of a finding. I am not exactly shocked or startled when it comes from this author.
