The role of bank deposits in Modern Monetary Theory

I get a lot of queries from readers about how the banking system operates. One recurring theme relates to the role of deposits in the banking system. Mainstream economic theory considers banks to be institutions that take in deposits which then provides them with the funds to on-lend at a profit. Accordingly, the ability of private banks to lend is considered to be constrained by the reserves they hold. While students find it hard to think outside of this construction, the reality is very different. Banks do not operate in this way. From the perspective of Modern Monetary Theory (MMT) private bank lending is unconstrained by the quantity of reserves the bank holds at any point in time. We say that loans create deposits. So then what is the role of deposits in MMT. That is the topic for today. I am deliberately simplifying to get the essential understanding across.

Budget deficit basics

I get many E-mails every week from people asking me to explain exactly what a deficit is. They understand that a budget deficit is the difference between revenue and spending but then become confused as a result of being so ingrained with narratives emanating from politicians and lobbyists who misuse terms and always try to conflate deficits and debt. So today’s blog is a basic primer on deficits and why you should welcome them (usually) and why we all should sleep tight when the government is in deficit. So – budget deficit basics …

I am now advocating biblioclasm …

So I guess it is time to build those very large bon-fires and burn all the mainstream macroeconomics textbooks that have poisoned the minds of millions of students for years. Mankiw, Blanchard, Barro to name a few. Burn them all. I also think it is time to delete all the computer code that supports mainstream economics models. My long-held belief that these actions would be educative and liberating have been ratified by a recent IMF conference that seems to have concluded that “the macroeconomic models that had been relied upon in the past and had informed major aspects of monetary and macro-policy had failed”. So all the supporting literature needs to be deleted. I am now advocating biblioclasm …

Monetary system not behaving according to textbooks – system is wrong!

In a speech in Maryland on January 7, 2011, one of the US Federal Reserve Governors, Elizabeth A. Duke spoke about current monetary trends in the US. It was hot on the heels of the testimony that the Federal Reserve boss Ben Bernanke made to the US Senate (January 7, 2011). They echoed similar messages. The reality is that the US economy is stagnating with very moderate growth and a very weak labour market. The overwhelming reliance on monetary policy as the saviour (low interest rates and quantitative easing) is misguided and will not provide the spending support that the private sector requires to regain their confidence again. But the interesting point to come from Duke’s speech was her observation that the US monetary system is not behaving according to how the mainstream macroeconomics textbooks (and thousands of orthodox teachers) depict it. That comes as no surprise when it is clear from the perspective of Modern Monetary Theory (MMT) that the textbooks are a joke. But given the monetary system is not “behaving itself” you can guess what all those mainstream professors are out there telling their students. Simple, the system is wrong!

The Australian economy loses to the snail

Three months ago, I wrote that Australia continues to grow but the signs are not all good in response to the moderating National Accounts data for the June quarter and associated data releases. My position in the national debate was lambasted as heretical and my competence was questioned because as all the bank economists, politicians, and related officials know Australia is close to full capacity and full employment and is about to burst at the seams courtesy of the “once-in-a-hundred” years commodities prices boom. My response, if only that was true! Sure enough, unemployment rose last month and there have been many signs that my judgement that the fiscal withdrawal and rising interest rates were cruelling growth was sound. Today’s Australian Bureau of Statistics release of the National Accounts data for the September quarter should shut those who are talking things up continually up. The Australian Bureau Statistics shows the Australian economy is growing barely faster than the zero line of no growth. And our so-called mining boom is not sufficient to generate a positive net exports contribution. The reality does not match the direction of policy or the rhetoric that is being used to justify the withdrawal of fiscal support. Bad luck if you are unemployed, underemployed or one of those that will certainly lose their jobs as employment growth stalls, again!

Money neutrality – another ideological contrivance by the conservatives

I have noted in recent weeks a periodic reference to long-run neutrality of money. Several readers have written to me to explain this evidently jargon-laden concept that has pervaded mainstream economics for two centuries and has been used throughout that history, in different ways, to justify the case against policy-activism by government in the face of mass unemployment. It is once again being invoked by the deficit terrorists to justify fiscal austerity despite the millions of productive workers who remain unemployed. I have been working on a new book over the last few days which includes some of the theoretical debates that accompany the notion of neutrality. There will also be a chapter in the macroeconomics text book that Randy Wray and I are working on at present on this topic. Essentially, it involves an understanding of what has been called the “classical dichotomy”. It is a highly technical literature and that makes it easy to follow if you are good at mathematical reasoning. It is harder to explain it in words but here goes. I have tried to write this as technically low-brow as I can. The bottom line takeaway – the assertion that money is neutral in the long-run is a nonsensical contrivance that the mainstream invoke to advance their ideological agenda against government intervention. It is theoretically bereft and empirical irrelevant. That conclusion should interest you! But be warned – this is just an introduction to a very complex literature that spans 200 years or so.

Wealth effects – been down that road before

In recent days, there has been some talk here about wealth effects and how they might complicate the interpretation of the multiplier. The claims made about that the multiplier understates the likely expansion as a result of the wealth effects is somewhat misleading but that is another story. The fact is that the inclusion of wealth effects has a long standing in economics. They were initially used as part of the mainstream denial that involuntary unemployment could exist in a market economy with flexible prices. This goes back to the famous Keynes versus Classics debates. In that debate, the mainstream argued that the wealth effects would be sufficient to restore full employment during a recession without any need for government intervention. The problem is that the ideas do not withstand scrutiny – either theoretically and empirically. They certainly do not provide a credible attack on the Modern Monetary Theory (MMT) claim that fiscal policy intervention is required to combat a situation where aggregate demand is deficient relative to the productive capacity of the economy. This spending gap manifests as involuntary unemployment in the absence of an appropriate policy response. Given the ideological position that these “wealth effects” have occupied in the literature I am always suspicious when someone proposes we take them seriously. That is what this blog is about.
