On the Wikipedia page for economist Ricardo Reis we learn he was “Influenced by: Greg Mankiw”, which basically should tell you everything. Everything that is that would lead to the conclusion that his macroeconomics is plain wrong. Yet his connections in the profession are strong and has prestigious academic appointments, is ensconced in senior editorial positions on influential economics journals, advises central banks in the US and has regular Op Ed space in a leading Portuguese newspaper (his homenation). These facts tell you what is wrong with my profession. That someone can write articles that are just so off the mark yet have significant influence in the profession and be held out in the public debate as to be someone who is worth listening to and being reported on. I have received many E-mails in the last few days about the proposal offered by Reis at Jackson Hole last week. Many readers are still confused and actually thought the proposal had credibility. Let me be clear – bank lending is not influenced by the reserve positions of the banks. Without credit-worthy borrowers lining up to access loans, the banks could have all the reserves in the world and the central bank could invoke any number of nifty ‘indexing’ or other support payment schemes on those reserves, and the banks would still not lend. And with those credit-worthy borrowers lining up to access loans, the banks will always lend irrespective of their current reserve position or the nifty support schemes the central bank might dream up. Core Modern Monetary Theory (MMT) 101!

I noted in Monday’s blog – Modern Monetary Theory – what is new about it? – that I am working on a paper (with my colleague Martin Watts) that will form the basis of a a keynote talk I will give at the – International Post Keynesian Conference – which will be held at the University of Missouri – Kansas City between September 15-18, 2016. That talk will now be held at 15:30 on Saturday, September. 17, 2016. I also listed four areas where we would discuss the novel contribution that Modern Monetary Theory (MMT) has made to macroeconomics, despite the claims of both mainstream economists and some Post Keynesians that there is nothing new in MMT. The first two blogs on this topic covered the juxtaposition of employment versus unemployment buffer stocks and the implications of that for how we view the Phillips curve, a central framework in macroeconomics linking inflation to developments in the real sector (unemployment etc). Today’s blog considers another section of the paper – the dynamics of fiscal deficits and public debt. We consider the difference between deficit doves, who consider fiscal deficits are appropriate under some conditions but should be balanced over some definable economic cycle, which we argue has been the standard Post Keynesian position, and the MMT approach to deficits, which considers the desirable deficit outcome at any point in time to be a function of the state of non-government spending and the utilisation of the productive capacity of the economy. We argue that fiscal rules expressed in terms of some rigid balance to GDP target are not only meaningless but dangerous. Fiscal rules in MMT are only meaningful if related to the state of non-government spending and the utilisation of the productive capacity of the economy. This body of MMT work is clearly novel and improves on the extant Post Keynesian literature in the subject which was either silent or lame on these topics.
