| Outline of Final Research Achievements |
There exists anxiety about future pension among the younger Japanese, because of longevity and decreasing population. One criteria of measuring pension risk is the income substitution ratio, which is the share of pension benefit to average worker income. Japanese government announces the 100 years simulation of reserve fund and the computer programs every 5 years. Under economic scenarios, the program minimizes the risk of pension benefit, as the reserve after 100 years is smaller than the benefit payment amount at the end. The policy to the risk is called “Macro Slide”, which cut the benefit against the inflation. The original program took a few minuets but we improve the optimization routine faster to less than minuets.
