False Skill Signals?
Lawrence Mishel of the Economic Policy Institute is skeptical of the claim that the US has a shortage of college graduates.
… This is because college graduates (those with bachelor’s degrees only) have not fared well in the labor market for at least 10 years—real wages are no higher than 10 years ago—while those with advanced degrees have seen their wages grow strongly. I have covered this ground in Education is Not the Cure for High Unemployment or for Income Inequality. In fact, those economists who argue that employment and wages are polarizing, such as Larry Katz of Harvard or David Autor of MIT, are pretty clear that employment outcomes for about half of college grads are part of the “middle” that’s faring poorly. That’s why it is misleading to use those analyses to argue that having more people go to college is the answer to growing wage inequality or middle-class wage stagnation; getting onto the better wage track requires either getting an advanced or professional degree (not just a college degree) or joining a clear subset of college graduates. That being the case, the arguments of those seeing “polarization” in the data lay out a very narrow track to good earnings and, in my view, further raise the issue of the need to make sure that those without college degrees, and many with college degrees, have good quality jobs.
