<p>The first class for Sanderson’s into econ courses deals with the same topic. He says that there are x students trying to get into the class who aren’t registered, how should he decide who gets in and who doesn’t? The early suggestions are to go by lottery, seniority (either direction), major (either preference for econ majors or for non-econ majors), looks, GPA (either direction), etc. Finally the concept of an auction is introduced. It’s a good, active first day that gives introduces concepts of efficiency and even equity.</p>
