There is no credit risk for a sovereign government
...UC Berkeley economist Brad DeLong...likes to think of himself alongside Krugman as part of the ``Keynesian'' army against all the neo-liberals. Both are in fact New Keynesians. In that sense, they are not very dissimilar to Mankiw and his gang. Interestingly, they appear to be continually trying to one-up Mankiw as part of some internecine struggle within the American economics academy. But from a Modern Monetary Theory (MMT) perspective, it is hard to tell their various narratives apart...a sovereign government is never revenue constrained because it is the monopoly issuer of the currency. That is a basic starting point in exploring the differences between spending and taxation decisions of a sovereign government and the spending and income-earning decisions/possibilities of the private sector entities (households and firms). The two domains -- government and non-government -- are very different in this respect and any attempt to conflate them as if both are subject to budget constraints is wrong and starts the slippery slide down into the total mispresentation of how the macroeconomics system operates...When a government runs a surplus it is not ``saving'' anything. The surpluses go nowhere! They are just flows that are accounted for and the aggregate demand which is drained by the surpluses is lost in that period forever...DeLong is actually teaching some bastardised course in Political Science here and only allowing the conservative side of the debate to be aired...HSBC economist Steven Major ...[writes in the Financial Times (FT)]...so contrary to what is being peddled each day in the financial press that a medal for bravery should be awarded...
