I'm looking at Public Policy programs. I'm in the same boat. Just finishing a M.A. in Econ, but I think I'll have a comparative advantage in a policy analysis type program, and my Gre scores have been too low for a Phd in Econ. Plus I'm not a superstar in math. I'm ok at it, but would probably struggle in a Econ Phd where, but I feel I would thrive in a public policy phd. I've yet to find a good forum that discusses admission to public policy programs. Grad cafe has one, but there isn't a lot of traffic.
Generally the Quant requirements are much lower for these programs. Have you found any schools you're targeting?
