Economics degrees are very common, and at most of the highly-selective LACs, economics is the top major (even at the (once?) famously counter-culture Wesleyan). Most of the Ivies (not LACs, I know) do not have business majors; instead, economics is considered the classic major that acts as a springboard to the business world, and this is certainly the case at LACs, where, currently, it seems that everyone is majoring in economics. If memory serves, it’s the top major at the “little three” (Amherst, Williams, Wesleyan).
