First, I have to give a HT to Dr. Mankiw, one of his posts today points to a YouTube video that offers a simple quiz about the relative sizes of the U.S. economy and the economies of other nations in the world. The information is essentially the same as something I pointed to in my post of June 20, 2007. It's formatted in a more interesting manner, and has a different objective than what I suggested. I encourage you to give it a look. If you can't view it at work, try it at home. Or vice-versa.
What do you think about it?
