要旨Abstract

　本稿では，労働者が勤務する事業所の運営主体が，労働者の賃金に与える影響について，比較研究を行う．日本の訪問介護労働市場に着目し，運営主体が営利目的か非営利かに応じて，賃金分布を比較する．また本研究では，先行研究が着目してきた平均賃金格差のみならず，労働者の背景属性で条件付けた賃金格差の分布についても推定を行う．結果，営利／非営利間の賃金格差は労働者の背景属性に応じて大きく異なることを示す．

　This study compares the impacts of operator type–non-profit and for-profit–on worker wages. Focusing on the Japanese home care labor market, we compare wage distributions according to whether the operator is a for-profit or non-profit. In addition to the average wage gap, on which previous studies have focused, this study also estimates the distribution of the wage gap, conditional on workers' background attributes. The results show that the wage gap between for-profit and non-profit firms differs significantly depending on the background attributes of workers.
