As a person who has a MA, and saw many people go to the job market with it, I can safely say you should definitely go for an MBA rather than the MA. Also I'm fairly confident that almost every U.S. MA program will give little to no funding. So, you should definitely count on having to pay for it yourself. While MBA's are expensive, I'm fairly certain you would recoup the cost faster in industry than you would with the MA. The fact of the matter is MBA's are far more valuable in the U.S. for now. If you fully intend to go for a PhD later, then the MA may not be a terrible idea, but I don't see many people going back for PhD's once they've started to make a substantial paycheck in industry. Not in economics anyways.
