What other offers do you have?
Did you receiving any funding.
They seem like a decent choice if you want to go work at a policy institute or aim high and go for WB or IMF. But it seems their academic placements are less than desirable. At least in the US.
I personally would consider GWU, but I got into BU and that pretty much sealed it because its a better program and they offer funding in years 2-5. From what I hear funding is hard to come by at all at GWU.
