... hey, what do your notes look like (no one ever has asked me that). So, in order to keep the people happy, here is my comparison of consumer surplus and compensating variation from Benefit-Cost Analysis course last week (click for a larger image [hope it is correct!]). Today I get to explain "consumer surplus without apology." I haven't worried about this stuff in a long time, but we have a layer of graduate students enrolled in the course this semester (did you hear that SACS?).
