University Course Choices

I have looked all over the forum finding out information about Economics and Management but i am still not sure which one to choose. I want to go into banking hopefully but i also want to start my own business and have knowledge of other business areas such as marketing. Below i have listed why i would want to choose economics and why i would want to choose management. I have also listed the negatives.

Economics
-Tells me about the world
- broard range of careers not only related to business
-interesting topics
- broard range of skills needed such as numerical and writing skills
- traditional and respected subject
- there is not many negatives but i wish it could focus more on some business aspects(i did contact university of birmingham who said i can choose some management modules which is very good)

Management
-broad and interesting
- at some university i.e southbank can be to vocational and not enough academics
-range of career paths
- i keep reading that business mangement doesn't have high employment rates

I like both subjects a lot so i considered apply for it combined but only a hand full of universities are doing that course so am not sure whether to do mangament or do economics with some management modules. If anyone has anymore information which can tell me about whether i can take business modules in economics or help with my choice in any way feel free cause am in need of some real guidance.

thanks for your time and help in advance
