I have recently had discussions with a PhD student of mine who was interested in exploring the cyclical link between productivity growth and the economic cycle in the context of the intergenerational debate about ageing and the challenge to improve the former. The issue is that sound finance – the mainstream macroeconomics approach – constructs the rising dependency ratio as a problem of government financial resources (not being able to afford health care and pensions) and prescribes fiscal austerity on the pretext that the government needs to save money to pay for these future imposts. Meanwhile, the real challenge of the rising dependency is that the next generation will have to be more productive than the last to maintain real standards of living and if austerity undermines productivity growth then it just exacerbates the ageing problem. My contention has always been the latter. That governments should use their fiscal capacity now to make sure there is a first-class education and training system in a growth environment to prepare us for the future when more people will have passed the usual concept of working age. This question also is hot at the moment in the Brexit debate in Britain and in this blog post I offer some empirical analysis to clear away some of the myths that the Remainers have been spreading.
