As indicated yesterday, Steve Keen and I agreed to foster a debate about where modern monetary theory sits with his work on debt-deflation. So yesterday his blog carried the following post, which included a 1000-odd word precis written by me describing what I see as the essential characteristics of modern monetary theory. The discussion is on-going on that site and I invite you to follow it if you are interested. Rather than comment on all the comments over on Steve’s site, I decided to collate them here (in part) and help develop the understanding that way. That is what follows today.

On July 8, 2009 a world first occurred in Sweden when the Swedish Riksbank (its central bank) made announced that its deposit interest rate would be set at minus 0.25. While this has set the cat among the pidgeons around the financial markets, it is a classic example of “central banking gone crazy” or more politely “quantitative easing on steroids”. The only problem is that performance enhancing drugs seem to make athletes ride or run faster. This move will do very little to make the Swedish economy increase output or employ more people. For a background to my analysis on this event in central banking history you might like to read my blog – Quantitative Easing 101.

In today’s Australian newspaper ex Federal Treasury official Tony Makin writes that We keep repeating Keynes’s mistakes. Do we now? The story is a litany of half-truths and basic conceptual errors. He is now a professor of economics. Bad luck for his students. The article, one of a regular contribution he makes to the increasingly squawking right-wing News Limited daily, is a classic example of how to deceive the public with spurious economic reasoning – that the author knows most of the public will just accept without question.

In yesterday’s (August 23 2009) Financial Times, so-called financial markets expert Nouriel Roubini wrote that The risk of a double-dip recession is rising. The American academic was recently in Australia as a speaker at the Diggers & Dealers Forum which is an annual mining conference. The problem is that Roubini is an influential advisor to the US Government and so will have a hand in determining the direction of fiscal policy. He continually demonstrates, however, that he does not understand how the fiat monetary system operates and in that context becomes part of the problem.

Why doesn’t this article get headlines in the newspapers? Today I read a recent article – Why Are Banks Holding So Many Excess Reserves? – from two researchers at the New York branch of the Federal Reserve Bank. It is obvious that the authors understand much more about the modern monetary system than most of the journalists, economists and politicians who make so-called informed commentary about such matters. Three messages emerge: (a) bank reserves play an important role in the conduct of interest rate policy and budget deficits put downward pressure on interest rates; (b) the money multiplier conception of economics is inapplicable to a modern monetary system; and (c) the current build-up of bank reserves will not be inflationary. I thought that it would be nice for you to read this stuff from someone other than billy blog (and my fellow modern money travellers!).

The euphoria over a 0.4 quarterly growth figure which translate into annualised GDP growth being at least 2.5 per cent less than would be required to keep the unemployment rate from rising should be attenuated by the fact that National Accounts data is very slow to come out. The picture it paints which conditions our current expectations and debates is old – at least 3 months old by definition. And it is sobering when amidst all the self-congratulation and applause for our strong export performance that newer data has come out today which suggests that GDP growth is probably now negative although we won’t find that out for three more months. Meanwhile the debt and deficits argument continues in the public debate. Here is an update.

Well the conservatives are scrapping between themselves, which is just as well because it might derail their drivel campaign about the trillion (whatever!) dollar debt wave that we are about to drown under. Me, I will surf it out with my longboard and enjoy the experience! Anyway, seems Mike wants to end our little engagement which is fine because tomorrow I will be talking about “R we or R we not”. National Accounts are out at 11.30. So this blog summarises where I think we are at. Remember that it started with the blog – Neoliberals invade The Greens! and the space theme continued with Mike conjuring up the Mitchell Strikes Back and today The return of Mitchell. Whatever, it is more clear than ever that the conservative macroeconomics has The Greens in its grip – sadly.

I was going to write about retail sales and company profits data today but the short story is that retail sales continue to defy the predictions (stimulus packages work). I ran a regression model today to generate a (reasonable) forecasting model of retail sales behaviour up to the point the stimulus packages were announced (November 2008) and then projected out to April 2009 and compared the dynamic trend with the actual data. Every data point since November 2008 is above the trend (which is why the ABS has abandoned its trend series for the time being). But it does tell you that the Australian economy is withstanding the world downturn. We will know more on Wednesday, when the national accounts (GDP) data comes out. Anyway, there has been more engagement with the “other side” or should I say “another side” today and I guess I should respond to that. And so the saga continues for another day.

In the days following my blog – Neo-liberals invade The Greens – I have had some interesting responses. Mostly they have been negative and personal but some have been positive and constructively trying to develop the debate. My blog was not an attack on green values – far from it. But it did pinpoint major macroeconomic failings with the current official policy of The Australian Greens which I consider need to be remedied in order to render the other excellent components of their platform viable. I would also note that it is very dangerous to start critiquing a theoretical argument if you really do not understand the basis of the argument. Here is some thoughts in this regard.
