Budget deficits do not cause higher interest rates

...An often-cited paper outlining the ways in which budget deficits allegedly push up interest rates is -- Government Debt -- by Elmendorf and Mankiw (1998 -- subsequently published in a book in 1999). This paper was somewhat influential in perpetuating the mainstream myths about government debt and interest rates...Their depiction of...Ricardian equivalence...alleges that: ``the choice between debt and tax finance of government expenditure is irrelevant...[because]...a budget deficit today...[requires]...higher taxes in the future...'' ...I have dealt with this view extensively...Ignoring the fact that the description of a government raising taxes to pay back a deficit is nonsensical when applied to a fiat currency issuing government, the Ricardian Equivalence models rest [on] several key and extreme assumptions about behaviour and knowledge. Should any of these assumptions fail to hold (at any point in time), then the predictions of the models are meaningless. The other point is that the models have failed badly to predict or explain key policy changes in the past. That is no surprise given the assumptions they make about human behaviour. There are no Ricardian economies. It was always an intellectual ploy without any credibility to bolster the anti-government case that was being fought then (late 1970s, early 1980s) just as hard as it is being fought now...So where do the mainstream economists go wrong? At the heart of this conception is the [pre-Keynesian] theory of loanable funds...where perfectly flexible prices delivered self-adjusting, market-clearing aggregate markets at all times...Mankiw claims that this ``market works much like other markets in the economy''...[assuming] that savings are finite and the government spending is financially constrained which means it has to seek ``funding'' in order to progress their fiscal plans. The result competition for the ``finite'' saving pool drives interest rates up and damages private spending. This is what is taught under the heading ``financial crowding out''...Virtually none of the assumptions that underpin the key mainstream models relating to the conduct of government and the monetary system hold in the real world...When confronted with increasing empirical failures, the mainstream economists introduce these ad hoc amendments to the specifications to make them more realistic...The Australian Treasury Paper [used advanced econometric analysis to find that] domestic budget deficits do not drive up interest rates. The long-run effect...is virtually zero. The short-run effect is zero!...toss out your Mankiw textbooks...

Your Textbooks Lied To You: The Money Multiplier Is A Myth

The following comes from an excellent new paper from the Fed. The paper describes the myth of the money multiplier and is an absolute must read for anyone who is trying to fully understand the current environment. It turns much of textbook economics on its head and describes in large part why the bank rescue plan and the idea of banks being reserve constrained is entirely wrong: ``Simple textbook treatments of the money multiplier give the quantity of bank reserves a causal role in determining the quantity of money and bank lending and thus the transmission mechanism of monetary policy. This role results from the assumptions that reserve requirements generate a direct and tight linkage between money and reserves and that the central bank controls the money supply by adjusting the quantity of reserves through open market operations. Using data from recent decades, we have demonstrated that this simple textbook link is implausible in the United States for a number of reasons...bank loan supply does not respond to changes in monetary policy through a bank lending channel, no matter how we group the banks...''

billy blog >> Blog Archive >> In the spirit of debate ... my reply Part 2

Today, I offer Part 2 of my responses to the comments raised in the debate so far...Modern monetary theory does not use the term ``money'' in the same way as the mainstream because it creates instant confusion. As Scott said ``Money is always someone's liability, so better to be precise about whose liabilities we are talking about than saying money.'' That is why we emphasis fully understanding the asset-liability matches that occur in monetary systems. And that leads you to realise that transactions between government and non-government create or destroy net financial assets denominated in the currency of issue whereas transactions within the non-government sector cannot create net financial positions...So modern monetary theorists prefer to concentrate on what is going on with balance sheets after certain flows have occured rather than narrowly defining some financial assets as money and others not...There is no doubt that the non-government institutions can increase credit. Some slack analysts call this an increase in money. But the accurate statement is that, as a matter of accounting it increases the (in Scott's words) ``the quantity of financial assets and financial liabilities 1 for 1 in the non-govt sector. So, with private credit, there is BY DEFINITION no NET increase in private sector financial assets created.'' Once we understand that and note that typically the non-government sector seeks to net save in the currency of issue then modern monetary theory tells you that the public sector must run a deficit to underwrite this desired net saving or else see an output gap widen...Who is in control is an interesting question. Clearly, the government cannot directly control the money supply which renders much of the analysis in mainstream macroeconomics textbooks as being irrelevant. The Monetarists via Milton Friedman persuaded central banks to adopt monetary targetting in the 1980s and it failed a few years later -- miserably...Then you might like to consider it from the other angle -- a government which accepts responsibility for full employment can ``finance'' the saving desires of the non-government sector by increasing its deficit up to the level warranted by the spending gap (left by the full employment non-government savings)...Orthodox macroeconomic theory struggles with the idea of involuntary unemployment and typically tries to fudge the explanation by appealing to market rigidities (typically nominal wage inflexibility). However, in general, the orthodox framework cannot convincingly explain systemic constraints that comprehensively negate individual volition. The modern monetary framework clearly explicates how involuntary unemployment arises. The private sector, in aggregate, may desire to spend less of the monetary unit of account than it earns. In this case, if this gap in spending is not met by government, then unemployment will occur. Nominal (or real) wage cuts per se do not clear the labour market, unless they somehow eliminate the private sector desire to net save and increase spending...to maintain high levels of employment and given that the public generally desire to hold some reserves of fiat money, the government balance will normally have to be in deficit...modern monetary theory demonstrates that if you want the non-government sector to net save...
