What we're going to do for the rest of the class, for the rest of the semester, is we're going to start to talk about how you apply those tools to more realistic situations.
Which is, in some sense what we've done so far is give you a set of tools to understand how to think about how consumers and producers make decisions, and then to understand how you compare positive and normative implications of economics. So this is actually, in some sense, a key breaking point in the course.
