Short video clips are a good way to get students interested in economics and help them understand the basics. I especially like the Golden Balls video for teaching game theory and Milton Friedman's classic telling of the pencil story for teaching price theory. The videos of Gerald Ford telling a joint session of Congress to "Whip Inflation Now"and of Arthur Burns telling a congressional committee that he would not increase the money supply are really good for macro.
2010 was a great year for new videos especially new cartoons, about which Amity Shlaes just posted a thoughtful article, Economics By Cartoon .
Here are some new videos which I think would be useful in the classroom if placed in context and used to generate discussion.
