Y'all may want to get your scroll bars handy. Last year I signed up for a macroeconomics class but it was cancelled. After I had purchased the book. So I vowed to do the classwork anyway, via self-directed study, since I had the book. Well, laziness and work drama set in, and I didn't get very far. However, given that I have free time now, I'm starting in earnest. This means I will be using this space to work through the problem sets in Principles of Macroeconomics like I did for my Microeconomics class last year. Feel free to comment with your own answers or just disagree with mine or scroll or unfriend or whatever suits your fancy.
