It is important to understand that economics and an undergrad business degree are very different paths. Economics is a liberal arts course of study and gets very theoretical at the upper levels. In contrast if you go to an undergraduate business school you will take a business core with introductory classes in subjects such as accounting, finance, IT, marketing etc. and then you will major in one of those disciplines. I’m not saying that one is better than the other, but they are different. I would take the time to look at the coursework (can be found online) for both a economics major and a business degree and see if one set of classes is preferable to you.
