This blog post by Steve Keen, Professor of Economics and Head of Economics, History and Politics at Kingston University London, is an excellent summary of the flaws of the Neoclassical Economics school of thought that currently dominates policy making world wide. In it, Steve also discusses alternative approaches to modeling the macro economy that made apparent the inevitability of a Global Financial Crisis well in advance. For those unfamiliar with Steve Keen's work in heterodox economics, this post should be a perfect primer.
Good stuff, and I'm interested in Keen (not sure I'll admit to being a fan yet, though he's interesting, rigorous, and is presenting some strong challenges to the economic mainstream).
I wish this had taken off a bit. I'd encourage you to resubmit it and ping [email protected] to see if it might get stronger visability. Though I suspect HN may not have sufficient economic depth to let this take off.
