Outline of Annual Research Achievements

事業期間最初の実績としては、解雇確率の上昇が起こった1997年以後、景気に対する賃金感応度にどのような変化が起こったのかを検証した、"Inequality through Wage Response to the Business Cycle; Evidence from the FFL Decomposition Method," 2019, Journal of the Japanese and International Economies, 51, pp. 87-98が挙げられる。その後、事業開始前には予測をしていなかったCOVID-19の発生により、コロナ禍前と後を比較すると賃金や働き方にも変化が生じた。そこで、事業内容にも微調整を加えながら、最新の研究を行ってきた。すでに出版された“What the COVID-19 School Closure Left in Its Wake: Evidence from a Regression Discontinuity Analysis in Japan”, 2021, Journal of Public Economics, Volume 195, 104364.では休校が母親に与えた影響を働き方含め、包括的に分析した。“How Serious Was It? The Impact of Preschool Closure on Mothers' Psychological Distress: Evidence from the First COVID-19 Outbreak”は、Japanese Economic Reviewから出版されることがすでに決定している。今後、これらのCOVID-19の結果も含めて、賃金や雇用の影響も含めたまとめを行っていく。

Current Status of Research Progress
Current Status of Research Progress

1: Research has progressed more than it was originally planned.

Reason

令和5年度には日本経済学会の女性研究者奨励賞を受賞するなど、仕事の範囲も広がり、より一層忙しさを増した。“How Serious Was It? The Impact of Preschool Closure on Mothers' Psychological Distress: Evidence from the First COVID-19 Outbreak” (with Reo Takaku)は、令和5年度末に査読付き学術雑誌に提出し、Japanese Economic Reviewから出版されることがすでに決定した。もうひとつのコロナ禍に関しての論文はRevise and ResubmitのStatusにあり、改訂稿を提出済みである。
“Is Asian Flushing Syndrome a Disadvantage in the Labor Market?” (with Daiji Kawaguchi, Jungmin Lee, and Ming Jen Lin), 2023, Health Economics, Volume 32, Issue 7, pp.1478-1503という論文もHealth Economicsに令和5年度に出版された。事業期間中執筆された他の全論文がRevise and Resubmitの状態にある。すなわち、これまでの蓄積してきた研究成果が、ほとんどのものは出版され、世間に公表されることとなった。その意味では、本研究の論文だけでなく、当初の計画にはなかった本議論と関連する付随的な研究に関しても、研究成果をあげることができたと言える。

Strategy for Future Research Activity

令和6年度は最終年度になるため、本研究の最終目標である問題点の取りまとめ(労働者のインセンティブ体系としての適切な賃金決定に関する現状と問題点の提示)および、給与体系により労働者の生産性を上げるための最適企業戦略を提言することを目指す。もちろん、コロナ禍前後で賃金や働き方にも変化が生じたことは事実である。コロナにまつわる残りの論文を出版し、コロナ禍での賃金や雇用の議論を含めた上で、この大きなテーマの最終的なまとめを行いたいと思っている。
