thank you, aisianeconomist! you are always very helpful.
BTW, here is my consideration
BU: one year program(a little short,), tuiition fee(32900$, expensive), in boston( maybe i get some chances to learn from top professors in the top schools, and so if i apply for the phd in boston I dont need to move), strong faculty(top school phd), courses level seems to be much lower than phd level,
BU | Economics
UIUC: 2 year program( can be 1 or 1.5), remedial english and math classes ( maybe I need to take, since my gre is so bad), policy eonomics (it is not economics, i dont know whether it will matter), strong faculty( top shcool phd), high level phd courses seem to be available to MS, courses design discussion with the faculty for each student
Enrichment, MSPE, University of Illinois at Urbana-Champaign
So, why BU is one of the few acdemic programs? so they have good placement for MA students?what schools do they get phd?
Thanks again for your help:)
