The latest release of our principles of economics class covers Externalities, Costs and Profit Maximization, Competition and the Invisible Hand, and Monopoly.
I am especially fond of our video, Trading Pollution, which explains the economics of tradeable pollution permits. Tyler and I worked with the incredibly talented team at Tilapia Film for a long time on a montage involving jigsaw puzzle pieces that’s near the middle of the video. The montage is only a few seconds long but I think it’s a beautiful way of illustrating how the price system draws upon information that is dispersed across many minds. There is a lot of deep economics behind the visual metaphors.
Addendum: For those of you using our textbook, this video and others are available directly from the textbook (using QR codes) and also available with assessment in our course management system, Launchpad.
