Economics or accounting degree? Watch
Firstly, economics is much broader and as such, doesn't close as many doors as an accounting degree, yet if you chose to go into accounting later on in life you could easily do this with an economics degree. In fact, depending on where you get your economics degree from it can actually be easier to become an accountant with economics rather than accountancy. The main reason for this is that accountancy is seen by many as 'softer' than economics and it is not respected anywhere near as much in the workplace.
At the end of the day, it's down to you but doing an economics degree will not close the accountancy door later on in life so don't worry about that.
Hope this was somewhat helpful.
