The recommended textbook for this class is Hal Varian's Intermediate Microeconomics, and the material we cover will roughly correspond to Chapters 18 to 37. The first two weeks (up to Jan. 12) correspond to Chapters 18-22 of Varian. Weeks three and four (Jan. 17 - Jan. 26) correspond to Chapters 31 and 32, but as we also cover material which Varian does not cover Victor Lima's lecture notes will be made available from the Social Sciences copy center (on first floor of 1126 E. 59th Street). In week 5 (Jan. 31 and Feb. 2) we address Chapters 34 and 36 of Varian, as well Ronald Coases's seminal article on externalities available here.

After the midterm (Feb. 9) we learn about monopoly (chapter 24 and 25 of Varian) then move on to basic game theory (chapter 28 and 29) on Feb. 14. An interesting paper on the empirical relevance of game theory is available here. From Feb. 16-23 we apply game theory to study oligopoly (chapter 27), as well as in the oligopoly chapter of Victor Lima's notes. The last three classes (Feb. 28-Mar. 6) deal with asymmetric information, something Varian addresses in Chapter 37. In addition, a seminal paper on the role of information in economics, Akerlof's ``Lemons'' model is available here. Furthermore, preliminary notes from Victor Lima on asymmetric information and Insurance will be distributed in class.
