Now, I know this is a physics forum, but I am interested in economics a bit. I am planning on competing in the Fed Challenge with a team from my school. I need to know macro-economics theory, which I do not. Does anyone know of a good textbook for macro? could I use an AP prep book? Thanks very much. PS - I have little-to-no knowledge of economics, so any books would have to preferably be fairly lower level, while still comprehensive and chock full of content. PPS - I wasn't sure which forum/subforum to stick this in, so I decided General Discussion couldn't hurt.
