Madsen's videos have proved to be a lot more popular than we expected, so we've decided to speed up their release to keep up the momentum. They're all based on his excellent new book, Economics Made Simple, which makes a terrific introduction to economics and markets, going from value and trade all the way up to banking and finance. We've mentioned the book on the blog before, but what I've only just noticed is how affordable the Kindle edition is — £2.40 for the full book! As a digital media enthusiast like me, that's exciting: as the overheads of book publishing fall, books like Madsen's will become even more available to everyone. Of course, the Youtube videos are free. Even if you don't buy the book, do share Madsen's videos far and wide.

Here's a playlist of the videos so far, and here's where you can subscribe to our YouTube channel so you don't miss any of our other great videos either.
