There is no single, sufficient condition for admission with financial aid. We look at a portfolio of items that include (not in any order): GRE scores (especially the Quantitative); transcripts; grades in math and economics courses; letters of recommendation; and the written statement of purpose. Each year, out of about 200 applicants, we offer admission with funding to approximately 35 Ph.D. applicants and 0-5 M.S. applicants.
What are my chances of funding?
