Outline of Final Research Achievements

The study examines the impact of childcare support policies on the dynamic behaviour of the economy, with an eye on Japan's declining birthrate and ageing population. It is often assumed that childcare support policies benefit only those households raising children and impose only a burden on families that are not raising children, which has been increasing rapidly in recent years. In such cases, political conflicts will arise against introducing the policy. In our model, we show that childcare support policies increase the sustainability of the social security system and can be a desirable policy for many households, including households without children. We also showed that this trend tends to be more pronounced in countries with higher current childcare costs and lower fertility rates.

Academic Significance and Societal Importance of the Research Achievements

少子化対策は多くの場合、出生率を増加させるような政策に焦点があてられる。これまでに多くの実証的な観点から、どのような政策が出生率を上昇させるのかについて議論がされてきた。ただし、その政策がどのように人々の効用に厚生に影響を与えるのかについての議論は不十分であり、理論的な観点からのアプローチは少なかった。本研究では、理論面も含めて様々な子育て支援政策を検討し、それぞれの政策によってだれがどのように負担をし、あるいは恩恵を受けるのかについても明らかにした。
