An amazing list of videos by some of the best economists can be watched here. It is a list of special lectures at the LSE, starting by the one recently given by Paul Krugman. You can find Johan Van Reenen and Hal Varian on Management and Growth, Lord Stern on Climate Change, Kahneman on his last book ("Thinking, Fast and Slow"), and Robert H. Frank on his recent book on evolutionary economics, consumption, taxation and inequality (which I will review soon upon request for a journal). It is a great progress that the Internet makes available for everybody the lectures of these people. In the past it would have been impossible to watch all of them in a single life time. And, by the way, the new (2011) edition of Robert Shiller's courses on Financial Markets are also available now. Peer pressure for us, more humble lecturers.
