Looking to major in Econ(not going into academia.) Probably financial services?
You can check the course listings.
Williams would have one of the strongest econ departments in the country without exception:
Of the colleges in the above link, the top seven (Williams, Wellesley, Middlebury, Wesleyan, Hamilton, Colgate and Claremont McKenna) also appear here . . .

. . . often outperforming universities 15 or more times their size.
Williams Econ is stellar, easily one of the best in the country. If you’re looking at finance, the alumni network and financial service firm connections here are really strong. However though Williams has a really strong Wall St. pipeline, other national universities such as Penn(Wharton), and Harvard and so on have stronger links to the financial services industry than Williams does.
