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.

Textbooks get out of date and need revision in the light of recent data or events. Some textbooks are exposed as being just plain wrong and should be re-written completely. Obviously authors in the latter category are reluctant to admit that their textbook is not an adequate description of the way – for example, the economy works – and so they not only resist updating their offering but they also defend it against all the evidence. Anyway, after reading Paul Krugman’s most recent attempt to come to grips with Modern Monetary Theory (MMT) I concluded that it was way past the date that he should be rewriting his macroeconomics textbook. Otherwise he is misleading the students who are forced to use it in their studies. So Paul, its time to update your textbook.
