The debate about austerity – and the relationship between public deficits, national debts and growth – has missed a crucial point. Unless countries are on the verge of a bond market strike, the amount of debt or the size of the deficit matter less than what activity the taxpayer is actually funding. If spending supports areas that increase growth rates via increases in productivity and innovation – such as education, skills, research and new technologies – then the long-run ratio of debt to economic output could be lower (and the state in better shape) than if its spending is less productive.
