billy blog >> Blog Archive >> In the spirt of debate ... my reply

Bill Mitchell

...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... We distinguish the horizontal dimension (which entails all transactions between entities in the non-government sector) from the vertical dimension (which entails all transactions between the government and non-government sector)...A properly specified model will show you emphatically that the horizontal transactions between household, firms, banks and foreigners (which is the domain of circuit theory) have to net to zero even if asset portfolios are changing in composition. For every asset created there will be a corresponding liability created at the same time...you will make errors if there is not an explicit understanding that in an accounting (stock-flow) consistent sense all these transaction will net to zero. In adopting this understanding you might abstract from analysing the vertical transactions that introduced the high-powered money in the first place, but never deny its importance in setting the scene for the horizontal transactions to occur. I think the differences between Steve's models and modern monetary theory are two-fold. First, I do not think that Steve's model is stock-flow consistent across all sectors. By leaving out the government sector (even implicitly) essential insights are lost that would avoid conclusions that do not obey basic and accepted national accounting (and financial accounting) rules. This extends to how we define money. Second, I think Steve uses accounting in a different way to that which is broadly accepted. It might be that for mathematical nicety or otherwise this is the chosen strategy but you cannot then claim that your models are ground in the operational reality of the fiat monetary system we live in. I have no problem with abstract modelling. But modern monetary theory is firmly ground in the operational reality and is totally stock-flow consistent across all sectors. If we used the same definitions and rendered Steve's model stock-flow consistent in the same way as modern monetary theory then Steve's endogenous money circuits would come up with exactly the same results as the horizontal dimensions in modern monetary theory. His results might look a bit different in accounting terms but most of the message he wishes to portray about the dangers of Ponzi stages in the private debt accumulation process would still hold.

Out of control US deficit spending [MMT introduction]

Regular readers know that, while I have a little of what Marshall Auerback calls deficit terrorism in my DNA, I fully support fiscal stimulus as a means to arrest a deep downturn...the US economy will not be able to sustain recovery for long without stimulus. The likely result of withdrawing stimulus is a recession that is deeper than the last one aka a major depression...a lot of talking heads are trying to bamboozle people with tales of woe about hyperinflation and sovereign bankruptcy in the US to support specific claims about what deficit spending can and can't do. Deficit hawks, in particular, are on the warpath...I am throwing in the towel on policy makers because it's clear that Obama has been captured by the deficit hawks and we are headed for a painful recession within the next two years...The policy debates aren't working because the actual mechanics of a fiat monetary system are being obscured by ideological political debates. So, what I want to do is lay the foundations of modern money with you so we can strip away the politics and ideology from the economics...

billy blog >> Blog Archive >> Zimbabwe for hyperventilators 101

Zimbabwe is the new Weimar Republic. Not! Zimbabwe is the front-line evidence that shows that government deficits will generate hyper-inflation. Not! Zimbabwe is the demonstration of the folly of a fiat monetary system. Not! Zimbabwe is an African country with a dysfunctional government. Yes!...Now at the risk of repeating myself a million times, this is the macroeconomic sequence that defines responsible fiscal policy practice. This is basic macroeconomics and the debt-deficit-hyperinflation hyperventilating neo-liberal terrorists seem unable to grasp it: [Mitchell summarizes modern monetary theory (MMT)]...So a responsible government will attempt to maintain spending levels sufficient to fill any saving....

billy blog >> Blog Archive >> The enemies from within

...Unemployment is the major source of poverty whether it be in a advanced or developing country. It is alienating, soul destroying, extends its costs well beyond the individual and the income losses alone dwarf the costs arising from so-called microeconomic inefficiencies. The daily loss of GDP involved in not having all available workers doing something productive is mammoth. It is a no-brainer that it is the large economic problem that should be solved in any country...If the private sector cannot produce enough then there is only one sector left ladies and gentleman who can do the trick!...Given the private sector doesn't want to spend at present -- and you cannot blame them for that given the appalling state of their balance sheets and the very unsteady housing market -- there is a danger that demand will drop further unless the government adds to its stimulus packages...the US is an economy that desperately needs more aggregate demand. The only constraint on employment is the lack of spending and there is no financial constraint that exists in a fiat monetary system that prevents the government from eliminating that demand deficiency...
