Ann Pettifor on mainstream economics: Ann has a article that talks about the underlying factor behind the Brexit vote. Her thesis, that it represents the discontent of those left behind by globalization, has been put forward by others. Unlike Brad DeLong, I have few problems with seeing this as a contributing factor to Brexit, because it is backed up by evidence, but like Brad DeLong I doubt it generalizes to other countries. Unfortunately her piece is spoilt by a final section that is a tirade against mainstream economists which goes way over the top. ...
Most economists have certainly encouraged the idea that globalization would increase overall prosperity, and they have been proved right. It is also true that many of these economists did not admit or stress enough that there would be losers as a result of this process who needed compensating from the increase in aggregate prosperity. But once again I doubt very much that anything would have changed if they had. And if they didn’t think enough about it in the past, they are now: see Paul De Grauwe here for example.
There is a regrettable (but understandable) tendency by heterodox economists on the left to try and pretend that economics and neoliberalism are somehow inextricably entwined. The reality is that neoliberal advocates do use some economic ideas as justification, but they ignore others which go in the opposite direction. As I often point out, many more academic economists spend their time analyzing market imperfections than trying to show markets always work on their own. They get Nobel prizes for this work. I find attempts to suggest that economics somehow helped create austerity particularly annoying, as I (and many others) have spent many blog posts showing that economic theory and evidence demonstrates that austerity was a huge mistake.
