Scores for quiz 3 are on Angel. The library should have three copies of the textbook on reserve by Wednesday (they told me).
Today's four slides are up. You need to understand the role played by our technical assumptions on preferences — completeness, transitivity, strict monotonicity, continuity and strict convexity.
Some general comments: Most of the stuff you should know for Wednesday's quiz was written or worked out on the board Friday and today. You can see the material presented from another perspective in the textbook (chapter 4), the workbook (sections 5-7), my very brief online writeup, or the links at the bottom of the writeup (in this case, to a site for a Stiglitz-Walsh chapter). You are expected to find and use these resources as needed in your studies outside of class. I hope they are easy to find from the website's front page.
