Q. Are there case studies for managerial economics?
We do have quite a bit of information over your topic. My search in the database Business Sources Premier (part of EBSCOhost) returned 108 results. See the attached screen shot for my search terms and first page of results. To avoid information overload, I recommend you refine your search criteria. Try to be as specific as you can so that you don't have to sift through a lot of irrelevant results.
