whoo boy, did I find out during undergrad Economics is not the same as finance (unless you are allowed to specialize or branch out to other related disciplines). Economics teaches you how to look at the entire world and U.S. economy, and hopefully a little about how to judge the competitivness of a firm or industry. Economics felt Wayyyy tooo Academic and high brow, and to me the econometric modeling smacked of...well...an attempt to use Science to explain Finance. I was a 5 year because I ended up dropping out of economics (changing majors).
Economics...to work for a bank? Did he want to be an investment manager or something, and judge the competitiveness of firms? His economic modeling wouldn't impress most banks much. Wrong major, what about finance - at least that way he could be a bookkeeper or the like for for a firm....or a Business degree teaches you some of the above, but also teaches you some of the nuts and bolts accounting etc for running a small business or the financial side of a corporation (depending on your specialty). What's he doing, studying the theoretical over the practical? Physics may actually be an apt comparison depending on what classes he took.
