Outline of Final Research Achievements

Complete elimination of females' time costs of both child-rearing and elderly care induces a 2 % increase in potential labor force and a 1% increase in the total GDP. If a gender gap in wage profiles completely vanishes, then the total GDP eventually expands by approximately 4 %. The replacement rate of the public pension scheme would become less than 50% from year 2039 even under that assumption that the accumulated pension fund is going to be used up completely by year 2115. Population aging leaves more burdens on the LTCI. In the next about forty years, the burdens on the first group (age 65 and over) and the second group (age 40 to 64) become more than 1.7 times and more than 2.7 times as much, respectively.
