For students using “economics” as a proxy for “banking and finance post grad”, Haverford probably edges out Carleton by virtue of proximity to NYC. Easier to do in-person events/internships, better known in that grography, more alums in the area, etc.
If it’s genuinely about a course of study, you may want to figure out where you think you’d be happier for 4 years. The academic calendar may or may not matter, the courses available and distribution requirements may differ, different study abroad opportunities might be approved at each.
Rarely is there a “better”. Just “better for you”.
