The additional events referred to in the editorial were events that were reported after the prespecified cutoff date and, therefore, these were not included in the primary analysis reported in thearticle.
Thearticle cited an analysis by a professor in Akita University that used generational accounting methodology to calculate the financial burden being placed on the next, unborn generation, of Japanese by current welfare system.
It may be over-stating the case, but I wonder if theanalysis above is one way to look at a phenomenon described in an article in the July 23 Nihon Keizai Shimbun, from which the graph at top is taken.
