She is a junior so still deciding. Are you a current senior or a junior deciding where to apply? It is so hard to assess fit without being able to be on campus, but from what you describe, you will likely find many students with similar interests. Writing is a big part of the culture and reputation, but there are many students who never take an English class!
Like most liberal arts schools, there are so many clubs on campus at both schools that you’ll have no trouble finding ways to try out sports, activism, arts, religion, service, etc. If you’re a senior making a final decision I’d recommend reaching out to the school(s) to ask to speak with a current student (and possibly a faculty member) in the econ department. The schools understand what a strange time this is, and I am guessing they would be happy to make that kind of connection for you.
