Since I published Wednesday’s blog – MMT is biased towards anti-crony – there seems to have been a fair bit of commentary on other sites some bordering on personal attacks (against me). I’ll steer clear of that level of discussion. I also note that John Carney over at CNBC responded with this article – Can the Government Guarantee Everyone a Job? – saying that if the notion of employment buffers is a central aspect of Modern Monetary Theory (MMT) then “it would mean that MMT is wrong”. I found his response interesting but essentially a rehearsal of the mainstream errors that arise when you haven’t really come to terms with what MMT is adding to macroeconomic theory. So today’s blog is a supplement to the Wednesday’s blog (and many others) and aims to provide some more context especially to those interested in the evolution of ideas and schools of thought. The point is that whatever else happens we are left with a choice – employment or unemployment buffer stocks. MMT provides the theoretical insights to show that employment buffers are superior whether you like them or not.
