Everywhere I look I find examples of politicians and leading lights making macroeconomic statements without understanding macroeconomics. Given that these statements have policy implications that impact on real people making such erroneous statements – no matter how well-intentioned one is – is a dangerous thing that we should avoid. Imagine if I suddenly started to make claims about the strength of bridges such that they would fall down if my advice was taken. There would be a law against that. One notable economist apparently thinks that macroeconomics is not “regular economics” – but rather some far-fetched misplaced set of ideas that would be better forgotten. My view is different. A correctly specified macroeconomics provides a safeguard against falling into logical traps – such as the fallacy of composition. The so-called “regular economics” is a fantasy world where the angels on the pinheads are assumed away into one representative angel who knows all and never makes a mistake (on average). If you want to understand how mass unemployment arises and how it is solved then the mainstream version of “regular economics” will leave you in the dark.

I know it is fashionable these days, particularly on the left to claim that class is dead – that its not about class any more – that left-right is dead – etc. But there was an interesting Bloomberg article (August 29, 2011) – Give Karl Marx a Chance to Save the World Economy – by one George Magnus, who is listed as a senior economic adviser at UBS Investment Bank. Confused? Why would a banker invoke the thoughts of the long-dead and usually vilified (by bankers) philosopher? For me it is always a normal part of thinking to go back to Marx because his dissection of capitalism – the sources of profits and the importance of seeing beyond the superficial exchange relations and thus understanding class relations embedded in production – has not, in my view, been bettered. And now a banker is suggesting that need to read Karl Marx.

Many people have drawn to my attention in recent weeks the evolution of the Modern Monetary Theory (MMT) Wikipedia entry and raised concern about the criticisms that are now on that site. I thought I better go and read the entry. I certainly have not added material to the site. Having said that I am happy that there is a page available. It seems that the criticisms cited are sourced to blogs by an Austrian Schooler, a graduate student blogger, and Brad DeLong. There does not appear to be an sound academic citation. The critics actually admit to basing their views on a cursory reading of the MMT literature and then only on the blogs that are out there now (including this one). The major claim is that MMT is just an accounting tautology. That just means they have read the first of hundreds of pages of MMT and then probably haven’t really grasped its significance. MMT is in fact an accounting-consistent, operationally-sound theoretical approach to understanding the way fiat monetary systems work and how policy changes are likely to play out.

I was reading an interesting study the other day that helps us understand why the macroeconomic policy debate is so awry at present. The paper – Cognitive dissonance, the Global Financial Crisis and the discipline of economics – by Adam Kessler an economist at a Florida university demonstrates that the mainstream economists who are highly influential in the current policy debate suffer from “cognitive dissonance” which leaves them in denial of the facts. CD leads to dysfunctional opinions and if these opinions carry weight in the public debate the policies implemented are also likely to be dysfunctional. It is a sad testimony that the mainstream of my profession is largely operating in a parallel universe but bringing their crazy ideas to our universe and pressuring governments to follow policies that damage a vast majority of people. One thing that is clear – the majority of these economists never have to carry the costs of their denial and retire on nice pensions. The same cannot be said for the victims of their arrogance and denial.

Yesterday I raised the issue of the dysfunctional political situation in the US which is preventing the US President from introducing a public works program aimed at boosting the degenerating public infrastructure. The fact that such a policy could generate millions of jobs and improve the long-term productive capacity of the nation is unquestioned. It was suggested that the US President might offer the conservatives widespread deregulation which would cut wages as a compromise. This would be pandering to their erroneous claims that that supply-side factors are restraining the capacity of American businesses to create work. Today we examine some recent research evidence that demonstrates how far amiss the current policy debate is. The evidence shows that firms are constrained by lack of spending at present and that the private sector is in a vicious cycle of spending paralysis. It suggests that the only way ahead is for the government to increase aggregate demand (via fiscal policy) but that the ideological obsession of the elected politicians is blocking the only growth option currently available. We are in a state where our politicians are deliberately stopping the economy from growing.

I have very (very) little time today and I am typing this in between meetings. There was a lot of non-news today – the news that pretends to be news and full of import but which in reality is largely irrelevant and just serves to flush out more nonsensical commentary from self-importance financial analysis (mostly located in private banks). Then the non-news commentary suffocates any sensible evaluation and in some cases governments are politically pressured to change policy in a destructive manner – fuelling the next wave of non-news. Today’s classic non-news was the downgrading of Japan by Moodys. Once again, a ratings agency declares itself irrelevant.

Earlier this year I reported on what a wonderful Xmas all the Ricardian agents (consumers and firms) had enjoyed in the UK as a result of the government austerity program. Please read my blog – Ricardians in UK have a wonderful Xmas. It seems those “agents” just cannot get enough of it. Now, more than 15 months into the austerity program and with the cuts about to really bite, the British economy continues to go backwards. Our real world laboratory is providing priceless data upon which we can assess basic propositions that mainstream macroeconomics provides and which Modern Monetary Theory (MMT) contests. A nation cannot have a fiscal contraction expansion when all other spending is flat or going backwards. Britain is up against an impossible equation.

Paul Krugman (August 20, 2011) was bemoaning the loss of intellectual values in the current debate when he referred to this Wall Street Journal article (August 19, 2011) – Why Americans Hate Economics. On face value I concluded that the WSJ had stumbled onto something – that the mainstream economics profession was not worth its salt. I was wrong though. The WSJ author was making a case that we should return to the economics that dominated the world prior to the Great Depression. The problem is that it is this way of thinking that represents the dominant paradigm today. It is the paradigm which has caused all the problems. It is this mainstream paradigm that people hate. The WSJ author is very confused. But then Paul Krugman’s response is hardly meritorious. So this is why the World hates economics – by which we mean mainstream New Keynesian macroeconomics.
