Contrary to the usual opinion on HN, this provides a good reason to do an MBA!
You should learn enough economics that if you are even a bit insightful you will avoid Econ 101 thinking, you will learn about things like intrinsic and extrinsic motivation, and a lot of other things relevant to management.
My MBA program mentioned in passing intrinsic / extrinsic motivation in the Ethics class - which in my program did not even have a final exam :).
Most of the time was spent on cost cutting, customer vs producer surplus, profit margins, efficient markets theory, lots marketing, lots of "the purpose of a commercial enterprise is to make money for its owner" said in different ways, and maybe some operations analysis.
