Some advantages of becoming a major in economics:

1.  Make better financial choices.
2.  Understand world events better.
3.  Prepare for a career in business, public policy, law, foreign service, etc.
4.  Hone your quantitative reasoning skills.
5.  The economics major usually consists of fewer classes than many other majors.

Some disadvantages of becoming a major in economics:

1.  Economics will not tell you exactly what you should do in every business decision you face in the future.
2.  Economics is fairly math-intensive.
3.  If you're planning on pursuing an MBA after graduation, economics may be too closely related to business for you to look like a "well-rounded" applicant.
4.  If you're only interested in what goes on in the real world, you may find economics too theoretical or unrealistic for your tastes.

    An economics degree can help prepare you for many different kinds of careers. Many economics graduates work for a while in the business world and then pursue an MBA. However, many employers in business look for well-rounded people who are conversant in fields like art and science, so if you are thinking of a business career and want to major in economics, you may want to consider minoring or taking a second major in something less business-related.
    Many economics graduates pursue careers in law. An economics major provides wonderful background for such students, especially those who are thinking about specializing in areas of law like property, contracts, regulation, taxation, and anti-trust law.
    Obviously, some economics majors obtain masters and/or Ph.D. degrees in economics or other closely related fields (like marketing, public policy, international relations, environmental studies, etc.). A Ph.D. will allow you to teach (either at the college or university level) or do research in governmental or other kinds of organizations.
