I've been wanting to do more with the health workforce. I just got bad news from my Mathematica fellowship application where I would have done some of that, but perhaps at some other point.
Health is one area where labor shortages are more plausible - not because labor markets fail to work, but because demand growth is so strong and persistent you could imagine that the workforces are constantly struggling to keep up.
That's been my prior.
But apparently that might not be the case either. See WSJ reporting here and here.
The first link highlights why a closer distributional look might be important (a good point that a commenter made to me yesterday about our EPI work).
