Hi all. We are approaching ¡­

Hi all. We are approaching the final lecture and the exam. I have received some requests for a topic for the last seminar. Prominent among these requests is the topic of general equilibrium with externalities which is what I'll start with. Also, note that the slides for Lectures 2 and 3 have been posted. They were never meant to be posted and they should be complemented with blackboard material so I don't know how useful they will be.
