In recent comments on my blog concern was expressed about continuous deficits. I consider these concerns reflect a misunderstanding of the role deficits play in a modern monetary system. Specifically, it still appears that the absolute size of the deficit is some indicator of good and bad and that bigger is worse than smaller. Then at some size (unspecified) the deficit becomes unsustainable. There was interesting discussion about this topic in relation to the simple model presented in the blog – Some neighbours arrive. In today’s blog I continue addressing some of these concerns so that those who are uncertain will have a clear basis on which to differentiate hysteria from reality. We might all sleep a bit better tonight as a consequence – hence the title of today’s blog!
