Later this week I will be in Japan for a series of presentations and meetings with a broad spectrum of Japanese politics. The various hosts of the events which I will confirm in Wednesday’s blog post are all committed to advancing an MMT understanding in Japan and ending the hold that ‘sound finance’ has on the public policy debates and regularly lead to poorly contrived policy shifts (such as the recent sales tax hike) in pursuit of lower fiscal deficits. As part of my preparation for my presentations I have been studying various aspects of the Japanese situation so that I can address the issues with a solid evidence base. One of the recurring themes put forward by the ‘sound finance’ lobby (which includes much of the economics profession both inside and outside of Japan) is that its ‘challenging’ demography demands that the Government move to surplus to ‘save up’ to avoid the impending fiscal disaster associated with a rising dependency ratio. This issue is not confined to Japan, of course. It is just that Japan’s demography is a little further down the ageing road than other nations. But while rising dependency ratios matter and need attention, the construction of the problem by the ‘sound finance’ lobby misses the point completely and their ‘solution’ to their ‘non problem’ only serves to exacerbate the real problem. That is what today’s blog post is about. In Part 2, I will elaborate more on the nature of the productivity challenge and some of the options that have been suggested to deal with it.
