As mentioned by other responses, statistics, data science, and econometrics are important classes to take to maximize your career opportunities. I also agree that taking another field of interest is useful, as economics can be used in many areas and having that education will make you stand out. This could be history, political science, the arts, etc. Also see if there are student clubs that focus on economics or "close substitutes" (finance, business fields) that would provide you with networking opportunities and job leads. If you are interested in working for government or a firm with your economics degree, I highly recommend that you join NABE (the National Association for Business Economics at www.nabe.com) as a student member. NABE has several student chapters at various universities around the US and is open to both undergrad and grad student participants. Even if there is not a local student chapter, you could attend the regional meetings as well as their national conferences/meetings. I highly recommend doing internships, as that will give you a much better idea of what economics jobs entail on a day to day basis. You can find internships at your school's career services center, JOE, NABE's job listings, or just creatively use Google to target firms of interest. I work for Disney, and we have many Professional internships in data science, finance, marketing analytics, consumer research that economics graduates would be a good fit for. Just google Disney professional internships if you want to check them out.
