Outline of Final Research Achievements

By focusing on the wage difference between male and female workers as well as the difference between full-time and non-full-time workers, this research examined the impact of an expansion of female labor supply on the Japanese economy, when labor supply by female workers is obstructed by child caring and nursing caring of their parents. The results indicate that the impact of more female labor supply on the Japanese economy is quite limited due to the fact the there is a huge wage gap between male and female workers. This result also suggests the importance of government policies to support female workers such as provision of on-job training to female workers while they are out the labor market, in order for them to improve their human capital.

Academic Significance and Societal Importance of the Research Achievements

将来の労働人口が減少することが指摘されている中、女性労働の重要性が益々指摘され、女性労働の確保と出生率の上昇が社会的にも大きく議論されてきた。当該研究では女性労働の確保において量的な確保では将来の安定的な経済成長にはかなり限定的で有り、むしろ質の改善が必要不可欠であることを示した。特に男女間の賃金格差、正規－非正規の違いが決定的に影響を与え、育児や親の介護で時間が取られている女性の労働を確保する際には質的な労働の改善、すなわち、育児休暇期間中などにおける研修などのサポートを通して、女性の人的資本の改善が必要不可欠であることを示した。
