Brian posted this link recently which offers a quick and easy interactive tool for playing with the Mundell-Flemming model. Great for when I don't want to get out yet another sheet of paper. (Brian posted another one for Solow.)
He also provided a video he found which nicely demonstrates growth in the world. It's a twenty minute show and really interesting. The topic also speaks to an interest of mine: being a better advocate for liberty. The lecturer didn't talk about liberty much but he did remind us of one of the few things all macroeconomists agree on; growth is good.
