Rethinking economics

If you decide to study economics formally, having already read widely around the subject, you'll probably notice something strange about your course. Many of the ideas and influences you'll have come across elsewhere scarcely appear in the academic curriculum.

Most economics taught today represents one particular approach. In the second half of the 20th century, neoclassical economics came to dominate academia to the point where "it represented perhaps 85% of the profession" and reduced other schools of thought to "several small rumps", says Steve Keen, professor of economics at the University of Western Sydney. As a result, it also dominates economic approaches in business, finance and politics, simply because it's the only economics that most students who go into these fields are taught.

There's a major problem with this, Keen claims: the entire approach is fatally flawed, built on unsound foundations and replete with contradictions from top to bottom. Debunking Economics sets out to correct this by tearing apart modern economics, showing where theory and practice fail and introducing competing views from other schools that have been submerged by the neoclassical consensus.

First published in 2001, this new edition has been extensively updated in the aftermath of the global financial crisis. The clear failure of many economic theories and policymakers such as Federal Reserve chairmen Alan Greenspan and Ben Bernanke, who were beholden to them provides plenty of extra material for Keen's criticisms. While it may not be likely that any reader will agree with all his views, many will concur that much of modern economics needs to be re-examined.

At least, those that make it through will. Keen has set out to write a critique of neoclassical economics, while also making it an introduction to these theories for those without much background in the subject.

That would be a difficult task in a book twice as long and proves impossible here: the text isn't dry, but some chapters would prove very hard going for the beginner. However, if you have studied economics or are planning to do so, this is an interesting and provocative read.
