Hi, I have two questions about some economics classes. First off, the economics department at my school is offering a special topics course on incomplete markets. Before I try to enlist in this class, I'd like to know what incomplete markets is all about. Also, do you need matrix algebra to be able to understand undergraduate econometrics? I was able to enlist into an undergraduate econometrics class, and I'm a bit apprehensive about taking it. Thanks!
