In May 2020, the IMF published a new Working Paper (No 20/73) – Hysteresis and Business Cycles – which provides some insights into what happens during an economic cycle. The IMF are somewhat late to the party as they usually are. We have known about the concept and relevance of hysteresis since the 1980s. In terms of the academic work, I was one of the earliest contributors to the hysteresis literature in the world. I published several articles on the topic in the 1980s that came out of my PhD research as I was searching for solutions to the dominant view in the profession that the Phillips curve constraint prevented full employment from being sustained (the inflation impacts!). The lesson from this literature in part – especially in current times – is that governments should do everything possible to avoid recessions. The hysteresis notion tells us clearly that the future is path dependent. The longer and deeper the recession, the more damaging the consequences and the longer it takes to recover while enduring these elevated levels of misery. Organisations like the IMF have never embraced that sort of reasoning, until now it seems. They certainly didn’t act in this way during the Greek disaster. But, better late than never.
Before Xmas, I published a two-part reply to Gregory Mankiw’s paper on Modern Monetary Theory (MMT) – A Skeptic’s Guide to Modern Monetary Theory (December 12, 2019). I was trying to get the response finished before the break and Part 2 had already become too long. So I decided to leave one issue that I didn’t get to address for a shorter third response once service resumed. I think this part of the response is necessary to set right on the public record. It exemplifies how critics need to work harder to actually understand what MMT is about. And while they try to claim that MMT is opaque and difficult to get to terms with, thereby sheeting the blame for their misguided renditions of our work back onto us, the issue I discuss today is very easy to come to terms with. It is front and centre and there have been many scholarly and other articles written about it. I refer, of course, to the Job Guarantee as MMTs response to the mainstream Phillips curve. The failure to appreciate where this sits in the MMT framework is not confined to mainstream economists. But this group know all about the Phillips curve literature and the place it holds in their macroeconomics. So there is no excuse not to understand it within a buffer stock framework and how MMT responds.
In – A response to Greg Mankiw – Part 1 (December 23, 2019) – I provided the E-mail correspondence that preceded the publication of – A Skeptic’s Guide to Modern Monetary Theory (December 12, 2019) – by Greg Mankiw. In this blog post, I provide a response to the specific points made in that paper and conclude that if it aims to be a fair ‘guide’ to MMT (even from a critical perspective) then it fails badly. So let me explain why I hold that view. Today’s post is long and will take some reading. It could have been a lot longer. But I intend to take a break from writing the blog until next week (the Quiz will appear as usual though), so you have plenty of time to read this longer than usual post. Normally, I would have spread it out over 3 or 4 parts.
On October 2, 2019, I received an E-mail from Gregory Mankiw. It was sent to me, Randy Wray and Martin Watts and asked us some questions about our textbook – Macroeconomics – which had been published by leading textbook publisher Macmillan in March 2019. The book has been selling strongly with a third printing already in the pipeline and a second edition coming, hopefully, later next year. Macmillan also publish Greg Mankiw’s macroeconomics textbook, which has been the dominant teaching book in undergraduate programs. I will take you through the E-mail correspondence that followed because it puts in context what Greg Mankiw decided to do next. Instead of continuing the correspondence on academic terms, which was a reasonable expectation at the time, given the initial approach and our replies, he decided to submit a paper – A Skeptic’s Guide to Modern Monetary Theory (December 12, 2019) – to the American Economic Association meeting in early January, which purports to be a ‘guide’ (meaning in English – a framework to convey an appreciation of something) to Modern Monetary Theory (MMT). After his initial entreaty and our responses in good faith, Greg Mankiw clearly decided that engaging with us on the terms he initially set out was not going to be in his interests and thus took another tack, without any further consultation or reference to his initial contact with us. I wasn’t impressed with that strategy. I was less impressed with the ‘guide’ that emerged. It says very little about MMT. It demonstrates how hard it is for someone deeply locked into a dominant but failing paradigm to think outside the ‘box’ for a while and try to understand that the ideas of a new and emerging paradigm cannot be meaningfully reduced back into the conceptual framework of the failing paradigm that the contender is seeking to usurp. I guess his strategy is understandable – after all – our book is now a direct competitor for his textbook and offers a new approach that has much stronger empirical correspondence. In that context, it is in Greg Mankiw’s self interest to attack our book in any way he can. The problem is that attacks have to have some foundation to resonate. Greg Mankiw’s attack is so lateral that he would have been better to have remained silent. Sure, he is playing to the mainstream groupthink echo chamber. But the echoes will die eventually as more and more people realise the mainstream is in its last death throes. This is Part 1 of a two-part response to Greg Mankiw’s paper. In Part 1, we review the E-mail trail that started all this. In Part 2, I will discuss his response.
Its Wednesday and some snippets only today. I was reviewing some data on public investment in the European Union the other day and up popped an article in Barrons that covered the same issue. The data reveals the stark failure of the Eurozone and the European Union, in general. The consequences of the European Union’s ideological obsession for rules over reality is now clearly undermining the future prosperity of the Member States. While the fiscal austerity has created elevated and persistent levels of mass unemployment, increased poverty rates, widening disparities between wealth and income, divergences in living standards across the Member States, what hasn’t been focused on much is the intergenerational consequences of the austerity. The data makes it clear that public investment in infrastructure has ground to a halt and in many cases, nations are not even replacing existing capital as it wears out. The quality and quantity of public infrastructure in place is crucial for general material prosperity and the future productivity of nations. While starving such expenditure may not have political consequences in the short-run – and this is why the austerity is partially focusing on cuts to investment spending – over times as the extant infrastructure deteriorates the the nation and the future generations lose out badly. Just another day in Europe! And across the Atlantic, the Democrats are proposing a ‘Balanced Budget Amendment’ to the US constitution. Madness on both sides of the sea!
It is Wednesday and despite being on the other side of the Planet than usual (in Helsinki at present) I am still not intending to write a detailed blog post today. I am quite busy here – teaching MMT to graduate students and other things. But I wanted to follow up on a few details I didn’t have time to write about yesterday concerning the role that NAIRU estimates play in maintaining the ideological dominance of neoliberalism. And some more details about the Textbook launch in London on Friday, and then some beautiful music, as is my practice (these days) on Wednesdays. As you will see, my ‘short’ blog post didn’t quite turn out that way. Such is the tendency of an inveterate writer.
It is Wednesday – so just a few observations and then we get down a bit dirty (funky that is). Today, I consider the GND a bit, critics of MMT, Japan, and more. Never a dull moment really. I didn’t really intend writing much but when you piece together a few thoughts, the words flow and so it is. The main issue is the recurring one – the lets have a little, some or no MMT narrative. This misconception regularly crops up in social media (blog posts, Twitter etc) and tells me that people are still not exactly clear about what MMT is, even those who hold themselves as speaking for MMT in one way or another. As I have written often, MMT is not a regime that you ‘apply’ or ‘switch to’ or ‘introduce’. An application of this misconception is prominent at the moment in the Green New Deal discussions. The argument appears to be that we should not tie progressive policies (for example, the Green New Deal) to Modern Monetary Theory (MMT) given the hostility that many might have for the latter but who are sympathetic with the former. Apparently, it is better to couch the Green New Deal in mainstream macroeconomic concepts to make the idea acceptable to the population. That sounds like accepting Donald Trump’s current ravings about the scourge of socialism. It amounts to deliberately lying to the public about one aspect of the economics of the GND just to get support for the interventions. I doubt anyone who thinks democracy is a good thing would support such a public scam. And so it goes.
It is Wednesday so just a few things to report and discuss. I have noted in recent weeks an upsurge in the Twitter noise about Modern Monetary Theory (MMT) and various statements along the lines that MMT economists are male chauvinists, mindlessly attack other heterodox economists because we are a religious cult, that we thrive on conflict, that only the US has a sovereign government and more. Quite amazing stuff. And these attacks are coming mostly from the so-called heterodox side of the economics debate although not exclusively. It is quite an interesting exercise to try to understand the motivations that are driving this social media behaviour. Things that would never be said face-to-face are unleashed with regularity these days. There appears to be a sort of self-reinforcing ‘echo chamber’ that this squad operate within and it seems to lead to all sorts of bravado that would be absent in face-to-face communication. None of the attacks seem to have any substance or foundation. They just reflect an insecurity with the way that MMT is creating awareness and challenging progressives to be progressive. And, they just make the Tweeters look stupid. I thought I would document some of the recent trail of nonsense to let you know what is going on in case you haven’t been following it. It is a very interesting sociological phenomena.
I am recording some promotional videos in London today for Macmillan Higher Education who will publish our forthcoming textbook – Macroeconomics on March 11, 2019. These will be the first of many short videos to support the teaching program outlined in the textbook. At last Friday’s very successful launch of the – Gower Initiative for Modern Money Studies (GIMMS) – I was asked a question at the end of the first formal workshop I presented, which I was unable to answer due to time constraints. The question went something like – “What do you think of the movements to instill pluralism into the teaching of economics?” The corollary was whether our forthcoming textbook adopts a ‘pluralist’ approach. The question implied that ‘pluralism’ was a desirable characteristic for a macroeconomics course to feature. In this blog post I discuss this question. It outlines what I might have said by way of answer to that question. But, given the medium, in a lot more detail than I would have provided at the actual event. Generally, we adopt a ‘pluralist’ approach. But it all depends on what we mean by that term. What we do not do is privilege the mainstream macroeconomics in any way. Too often, those who call for ‘pluralism’ in economics think it is appropriate to force students to learn swathes of the mainstream theory and practice as if it is knowledge. They think this is somehow a liberal approach to learning. Our view is that learning is about knowledge accumulation. Universities are not places where ‘fake knowledge’ should be disseminated. That is what propaganda is about.
It is Wednesday and so just some snippets. I have written about the behavioural impacts that studying mainstream economics, particularly the microeconomics component can have on students as they progress through their studies. I have observed sort of nice young people entering first-year and by later years, become arrogant, self-opinionated and delusional jerks. This phenomenon is particularly prominent if they go onto to do postgraduate level studies. It is well documented. The way mainstream economics is taught builds on anti-social attitudes that might already be present in students who choose to undertake this sort of training. The curriculum matters a lot. In that context, our next macroeconomics textbook (see below) will, in my view, actively work against any predisposition towards selfishness and against altruism, while still providing students with a first-class, technical education in how the monetary system operates.
