Here is some twisted logic if you ever saw it. Sydney Morning Herald main economics writer Ross Gittins wrote yesterday that the Opposition leader’s scaremongering about the build-up of debt is a faux concern and amounts to hysteria. So he sets about soothing us with some explanation. But it is the explanation that leaves out some of the more important insights which if known would alter the way the reader understood the article and the issue being discussed.

I am often sent E-mails asking me to explain succinctly (what my other explanations are not!) how public deficits finance saving. What does it mean? How does it work in a macroeconomic system? What is the difference between automatic stabilisers and discretionary budget dynamics? What would have happened if the government had not have increased the growth in spending? All these sorts of questions. So this short blog – to make up for yesterday’s ridiculously long blog – will cover those issues. It should clear up any outstanding issues about why deficits are important to underwriting growth.

Yesterday, regular commentator JKH wrote a very long comment where he/she challenged some of the statements and logic that modern monetary theorists including myself have been making. While I don’t want to elevate one comment to any special status – all comments are good and add to the debate in some way – this particular comment does make statements that many readers will find themselves asking. In that sense it is illustrative of more general principles, points etc and so today’s blog provides a detailed answer to JKH and tries to make it clear where the differences lie. Some of these differences are at the level of nuance but others are more fundamental.

In November last year, during a visit to the LSE, the Queen of England (and Australia to our eternal shame) asked some pointy heads why “if these things were so large, how come everyone missed them?” in relation to the apparent inability of the mainstream economics profession to foresee the crisis. Apparently, the Royal Academy then called a special workshop to discuss this and came up with an answer which they then relayed post haste … as “Your Majesty’s most humble and obedient servants” to Liz. The whole affair represents the standard massive denial that defines mainstream macroeconomics. There are no saving graces. It would be useful if they just desisted for a while and went and played gin rummy.

The public debate is constantly distorted by claims that cannot be substantiated. One such claim is that the current period of budget deficits is building a stock of future claims on the well-being of the future generation – our kids. Accordingly, the neo-liberal deficit terrorists claim that the best thing we can do for the future generation is to avoid running deficits. My view is that we have been imposing a huge future burden on our children but this would be larger if we tried to run surpluses now. In fact, the years of surpluses exacted a huge toll on our children’s prospects that they will have to endure for years to come.

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!).
