I'm not an entrepreneur, MBA, or econ major (did take some classes in college, continually read up on the subject), so take this with a grain of salt. There's a tremendous amount of overlap and shared concepts, but probably going to need to know more about business/finance than economics per se. Some of the busywork can be farmed off to an accountant/lawyer, but you'll need to understand pricing, unit economics, profit and loss and basic accounting principles. If you're interested in taking investors, you'll need a very good understanding of terms and preferences to avoid getting screwed, and you'll need to be able to talk about business plans realistically to make a pitch. If you start to take on multiple employees, there is a tremendous amount of knowledge (both intuitive and book-learning) about organizational behavior and management that you'll need to internalize.
