Readers of my blog often ask me about how modern monetary theory sits with the views of the debt-deflationists (and specifically my academic colleague Steve Keen). Steve and I have collaborated in the last few days to foster some debate between us on a constructive level with the aim of demonstrating that the common enemy is mainstream macroeconomics and that progressive thinkers should target that school of thought rather than looking within...hopefully, this initiative will broaden the debate and bring more people up to speed on where the real enemy of full employment lies...The modern monetary system is characterised by a floating exchange rate (so monetary policy is freed from the need to defend foreign exchange reserves) and the monopoly provision of fiat currency. The monopolist is the national government. Most countries now operate monetary systems that have these characteristics...the monetary unit defined by the government has no intrinsic worth...The viability of the fiat currency is ensured by the fact that it is the only unit which is acceptable for payment of taxes and other financial demands of the government.The analogy that mainstream macroeconomics draws between private household budgets and the national government budget is thus false. Households, the users of the currency, must finance their spending prior to the fact. However, government, as the issuer of the currency, must spend first (credit private bank accounts) before it can subsequently tax (debit private accounts)... Taxation acts to withdraw spending power from the private sector but does not provide any extra financial capacity for public spending...As a matter of national accounting, the federal government deficit (surplus) equals the non-government surplus (deficit). In aggregate, there can be no net savings of financial assets of the non-government sector without cumulative government deficit spending...contrary to mainstream economic rhetoric, the systematic pursuit of government budget surpluses is necessarily manifested as systematic declines in private sector savings...Unemployment occurs when net government spending is too low. As a matter of accounting, for aggregate output to be sold, total spending must equal total income (whether actual income generated in production is fully spent or not each period). Involuntary unemployment is idle labour unable to find a buyer at the current money wage. In the absence of government spending, unemployment arises when the private sector, in aggregate, desires to spend less of the monetary unit of account than it earns. 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. Thus, unemployment occurs when net government spending is too low to accommodate the need to pay taxes and the desire to net save...Unlike the mainstream rhetoric, insolvency is never an issue with deficits. The only danger with fiscal policy is inflation which would arise if the government pushed nominal spending growth above the real capacity of the economy to absorb it...government debt functions as interest rate support via the maintenance of desired reserve levels in the commercial banking system and not as a source of funds to finance government spending...there is no intrinsic reason for...
