I strongly recommend you to evaluate your decision carefully and completely.
It is obvious that any candidate with science or engineering background may easily shift her/his major,
however, you'd better consider your career integrally and in the long run.
I believe candidate with science or engineering degree takes more initiatives in his/her future career development.
Economy or administration is pretty easy, you may learn it all by yourself later.
Trust me, you can.
But, very few can do reversely.
I wish you good luck.
A hot title won't mean much in your whole life.
