| Outline of Final Research Achievements |
This research involved various studies on Japan’s non-regular workers. To evaluate various problems qualitatively and quantitatively, empirical analysis was conducted using microeconomic datasets and theoretical macroeconomic models were also used. They include characteristics of non-regular employment based on wage prospects, job transition between regular and non-regular jobs, and employment status persistence. In addition, Japanese firms’ long-term employment practices were reexamined from the dual structure viewpoint, as well as the effects of household economic risks on the fertility rate, and the labor demand factor decomposition of increases in the number of non-regular workers.

| Academic Significance and Societal Importance of the Research Achievements |
雇用者の4割近くにまで増加した日本の非正規労働者の特徴と、その増加の要因と影響について、賃金、労働移動、長期雇用慣行、出生率、労働需要などの多様な観点から、ミクロ経済データによる実証分析を中心に、事実の提示と量的・質的評価を行った。とくに、現在でも長期雇用慣行は正規雇用労働者において堅固に残っており、非正規雇用の増加は正規雇用部門の縮小を必ずしも意味しないことを示す複数の実証的事実を提示した点は、雇用政策に対する含意が大きいと考える。また、因果関係に配慮した分析手法によって、量的評価を行っている分析も多く、雇用関連政策の効果に対する情報となる。
