I know this is an indirect solution, but why even have papers in a business course anyway? I was a business undergrad, and after all of the lower-level BS classes, it was all about projects and discussions in class, not paper writing. Any long-form writing I had to do was in-class writing essays and stuff on exams, where you can't copy paste.

I know a lot of the CS people on here look down on business education, but the real value in it is not learning specific facts like "what is WiMax" but instead being able to work on a team to create something and being able to communicate and discuss business problems intelligently.

The team projects and case study discussions is really where I learned things. Traditional assignments in a business course don't really make a lot of sense.
