Recent Thoughts

Recently I have been analyzing ways to mitigate the speed of Japan’s declining birth rate and ways of achieving gender equality in Japan with work-life balance as the central concept, and I have also been making policy recommendations related to these issues. I would like to see those policies become as evidence-based and consistent with the understanding of human mind and human behavior. Furthermore, in panel data analysis, I plan to develop more advanced use of latent class variables than is presently being practiced, thereby providing a more vivid description of the relationship between social conditions and various aspects of people’s life choices and life stages that cannot be directly measured.
