I've been terrible posting new problems for you. I have excuses - but they're not good enough. I'll get more on here tomorrow to challenge your brain. I've already promised - two weeks (less than that!) and we'll kick back and relax a little bit.
All right - something to think about. Go to this link (open it in another browser): http://www.collegeboard.com/prod_downloads/ap/students/economics/ap04_frq_micro.pdf
These are the three short answer questions from last years' exam. Skip the first one - that deals with externalities, which we will get to this week. See what you can do with the second and third ones, though. You have the info to work with those.
In fact, #2 can be answered completely here. Any takers?
