I've been trying to access the papers that state that kind of problem, but most of them need payment for access and I am on a student budget.

I know that maximizing profits=maximizing stock value in a world of certainty, but why is that maximizing stock value will be different from maximizing expected profits in a world of uncertainty?

If you're a student, then you can typically access papers at your library. It's not quite clear to me what you're asking. You might find this informative: papers.ssrn.com/sol3/papers.cfm?abstract_id=146148 –  John May 13 '14 at 14:24
It is microeconomics question. I'm not sure, but the whole thing started with a seminal paper of Peter Diamond in 1967 (which I cannot access for now). –  John Doe May 13 '14 at 15:15
This one (found simply by googling Peter Diamond 1967)? ibe.eller.arizona.edu/docs/2008/Segal/… –  John May 13 '14 at 16:21
No, it is "The role of a stock market in a general equilibrium model with technological uncertainty" (1967). Hal Varian, in his "Intermediate Microeconomics: A Modern Approach", 8th edition, makes the comment that (I'm not quoting the exact words), in a world of uncertainty, it is difficult to assign a meaning for maximizing profits, but maximizing stock market value (which is the same as maximizing profits in a world of certainty) still has a meaning. –  John Doe May 13 '14 at 19:55
I don't have access to that paper. I suggest you get a copy of it from your library. If you have any questions, your professor is likely to be able to provide better answers on this type of question than this site will. –  John May 13 '14 at 20:46
