I don't think he's talked about it on his site yet, but Tyler Cowen has a new book coming out called Create Your Own Economy: The Path to Prosperity in a Disordered World.
As economist Tyler Cowen boldly shows in Create Your Own Economy, the way we think now is changing more rapidly than it has in a very long time. Not since the Industrial Revolution has a man-made creation -- in this case, the World Wide Web -- so greatly influenced the way our minds work and our human potential. Cowen argues brilliantly that we are breaking down cultural information into ever-smaller tidbits, ordering and reordering them in our minds (and our computers) to meet our own specific needs.
Create Your Own Economy explains why the coming world of Web 3.0 is good for us; why social networking sites such as Facebook are so necessary; what's so great about "Tweeting" and texting; how education will get better; and why politics, literature, and philosophy will become richer. This is a revolutionary guide to life in the new world.
I never properly reviewed Cowen's last book (sorry!), but I found it as enlightening and entertaining as Marginal Revolution is. (via david archer)
