I have noticed that the top major at a lot of Colleges is Economics. I don’t want to get lost within the crowd, so what are some other subcategories I could major/minor in to make me stand out more than the plain old Econ majors?
What’s going to make you stand out (presumably to employers?) is not your major by itself, but what you do with it.
An economics major who has strong quantitative skills, knows how to program in Python or Ruby, and has 2-3 internships under his belt? Stands out. An economics major who spent a summer at the IMF, the World Bank, or administering microfinance programs in West Africa for a nonprofit? Stands out. An economics major who does an independent project with economics professors and publishes it or presents it at national conferences? Stands out (although perhaps more to grad programs than employers).
If you want to major in economics, major in economics - but then do internships and jobs and/or learn skills that make you stand out.
@juillet The main thing I was asking is what are the sub-categories that can play into economics (i.e. finance, business, etc.).
Sanskrit?
@DrGoogle Thanks for the suggestion 
Here’s how the [Journal of Economic Literature](American Economic Association) has classified academic fields of economics. There is a subfield called financial economics, which is related to finance. There’s also one that refers to business economics specifically. A lot of these subfields are individually related to business.
Virtually anything can play into economics. You can pair political science and economics to get political economy. You can pair psychology and economics to get behavioral economics. Economics and math produces game theory or econometrics. Economics and history yields historical economics (I actually helped an undergrad student with a quant project in historical economics when I was teaching). Earth science/environmental science and economics makes environmental economics…you get the picture.
I guess the question is…what do you want to do?
@Dylan197 Neither finance or business is under the umbrella of economics. A school may have other focuses under economics (international, labor economics, economic history, etc.), but most schools I’ve seen simply teaches you a bit of all.
AFAIK, there aren’t really subcategories to economics, and finance and business certainly do not go under economics.
EDIT: @juillet proved me wrong. However, financial economics won’t teach you everything you need to know for a finance career, unless it is a business degree.
@Woandering, I was going to say the EXACT same thing until I did a search to see if someone had published on the subfields of economics, lol. I never thought of finance and business as under the economics umbrella. I’d still argue that they aren’t - just like psychology isn’t, but there’s still such a thing as behavioral economics because they can be blended/related.
I also want to point out that while I found it to answer the question, undergrads wouldn’t specialize anyway (with the exception of a few programs). You’d major in economics and get a broad education in the field.
