Hi!I am starting to realize that my best path is to go the "european masters as a stepping-stone" route.How is the difference in admissions between say Barcelona GSE/CEMFI/LSE/Bocconi vs. say a top 20 US PhD program in terms of math? Do the mentioned masters programs require real analysis for instance? Or is it sufficient if I have full calc sequence + Lin Alg? I am an econ major btw, so I have most of the econs + stat courses.
