It’s taken us a few years to tackle the obvious topic for the Debunking Economics podcast, what are the biggest failings of neoclassical economics. Prof Steve Keen tells Phil Dobbie that it starts on page one of rudimentary economics textbooks, which the idea of the demand curve. Having debunked that, he moves on to the capital market line, used to determine investment decisions. Then it’s the models being used to determine the impact of climate change. Then the concept of diminishing marginal productivity. And finally, the process of simplifying assumptions. Having dismissed all the major tenants of economics Phil asks Steve if there any laws that apply to the ‘science’, in the same way that gravity applies to physics. Or is it all lost in the realm of unproven speculation?
