I thought of a couple short and intuitive, but perhaps forgettable, formulas to provide for tomorrow's test (in response to a question in class). So I'll write the formulas associated with the zero-cost monopolist's pricing rule and the tax-incidence breakdown on the board tomorrow. I think they might be more confusing than helpful, though, what with the Greek notation. I'm open to further suggestions: are there any long formulas that cannot be figured out with a good understanding of core concepts?
We did not look at most of today's slides, but you may wish to do so for review. Keep in mind that most of the material on those slides goes beyond what will be tested. See slide 2 for clarification on this point.
Good luck tomorrow,
