Several readers have E-mailed about the concept of a multiplier in macroeconomics particularly in light of comments I made yesterday about the current debate as to whether the deficits will be expansionary and whether it would be better to cut taxes rather than increase spending. There appears to be a lot of confusion about the most basic concepts involved so this blog seeks to address some of those issues. It is not a comprehensive literature review.

Several readers have written to me asking about the Ricardian equivalence theorem, which is increasingly getting mentioned in the media and public policy reports. As I will explain, the theorem is used by anti-government proponents to argue that fiscal deficits are counterproductive and that cutting deficits in the middle of a recession will actually be good for the economy. They never really give up, do they? The theorem is a good example of the general mainstream approach where stark policy conclusions are derived which capture the popular debate but the underlying assumptions that are required to generate those conclusions are rarely widely known or mentioned in the popular press. Of-course, if the public understood these underlying assumptions then they would not take the conclusions seriously.

In the coming period and probably years you should expect to hear, read and be submerged with mainstream economists coming out and assessing the structural budget deficit. Across most economies, these so-called “experts” will be arguing that the structural deficit in the nation is too high and deep cuts are needed to bring it into surplus. The importance of this debate is that they use the structural deficit estimates as an indicator of the fiscal stance being taken by the government and thus separate out the effect of the automatic stabilisers. The problem is that it is an inexact science. The mainstream approach is highly dependent on the NAIRU concept (see below) and thus will err on the side of concluding that the deficit is “too big” and “likely to cause inflation”, whereas it is probable that the deficit will be too small to underpin private savings and high levels of employment.

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.

I am now in New York on business for the next few days then off south to the capital Washington. In this blog I want to outline the horrible scenario that everyone has been predicting would happen – the increasing fiscal deficits will increase taxation. I know that has been on our minds. I have reached the ineluctable conclusion that future taxation will increase as a direct consequence of the current deficits. The tax revenue gained by the government will also reduce future deficits. Wouldn’t it be preferable that we didn’t push future taxation up and instead controlled net government spending? If you believed that you would have rocks in your head. In this blog I will be also be discussing debt, inflation, and other nasties.

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.

I must have just woken from a bad dream. Did I read this week that the Australian Government will record a deficit of $A58 billion or 4.9 per cent of GDP but are forecasting unemployment will rise from its present parlous level of 5.4 per cent to 8.5 per cent by the middle of 2012? It must be a joke. If it is serious then this lot deserve to be a one-term government not that I have any hope that the alternative (conservative or green) would do any better. They are all caught up in this neo-liberal straitjacket which has been increasingly tightened over the last 30 years and now ensures that our national government will not use its economic policy capacity responsibly. Our current Federal Government not only continues to abandon full employment but is also abandoning the unemployed. What a place!

The ABC News Online business reporter Michael Janda ran this Opinion piece – Economists tackle the deficit and debt debate today. He interviews three economists – myself, Steve Keen (University of Western Sydney) and Stephen Kirchner (Centre of Independent Studies). The discussion is interesting because it demonstrates how the journalists modify what you say to mean something slightly different (no accusation here that it was designed to skew meaning though) and generates the statistic that two out of three economists do not understand how the modern monetary economy works.

I read the headline – Aussies don’t understand deficits: MP – in the Canberra Times with interest and after reading the article I returned to the on-going conversation I have with myself – why have we all been so stupid to have been so duped by the neo-liberal agenda? Almost all the public debate about the Federal Budget tomorrow is a total non sequitur. It bears no relation to the important questions that the Budget process has to deal with. Somehow, we are all sidelined by a rhetoric and a focus that conveniently diverts us away from these real issues and, instead, transfixes us on a piece of fiction. But a convenient fiction which maintains the relative power elites and perpetuates disadvantage. I understand all of that … but I still can’t get my head around why we have allowed ourselves to be so conned.

Today I am in Melbourne (my home town) presenting a workshop on skills development for the new green jobs economy which is a joint Victorian Government/Brotherhood of St Laurence show. But that is not what I am writing about here. Regular readers of billy blog will know that when I talk about budget deficits I typically stress two points: (a) that the Government is not financially constrained and therefore all the hoopla about debt and future tax burdens are just a waste of time. But just because the Government can buy whatever is for sale by crediting relevant bank accounts doesn’t mean they should not place limits on the size of the deficit; and so (b) given the federal deficit “finances” private saving, it should therefore be aim to “fill” the spending gap left by the private desire to save. If the Government does that then it can maintain full employment and price stability and move towards a more equitable society. So it is of importance that we have some idea of the size of this spending (or output) gap.
