<p>You should look on a course basis. Usually, business majors get more funding and have better resources. I was excited about taking one class (intermediate macroeconomics), which is a fundamental course in the sequence after basic economics, and ended up having to drop because the instructor was an asian grad student who could not articulate herself properly in english, so after the first day, I had to leave otherwise I knew I would be miserable for the entire semester. It is very important for professors to be qualified, and having a grad teach this intro course might tell you something about the calliber of the department, but I am definitely not sure. You would have to investigate it further-- that was only my single experience with one class.</p>
