男女賃金差別と年功賃金森ます美『日本の性差別賃金』の検討

摘要

Today the opinion is generally shared that seniority-based wages in Japan are built on personal attributes rather than on work performance and therefore conducive to gender-based discrimination, However, when we examine typical movements aiming at reforming gender-based wage discrimination, we recognize an important role played by seniority-based wages as valid criteria or justification for advancing the ongoing reform. Therefore the issues as to whether wages are determined by personal attributes or by work performance should be considered to belong to dimensions different from those of the issues as to whether gender-based discrimination is strong or weak. Accordingly, the opinion that seniority-based wages are essentially gender-discriminative does not hold true empirically and theoretically. We should note that this misunderstanding concerning seniority-based wages may lead to a non-evidenced conclusion that pay-for-performance systems are generally desirable. These aspects are examined with reference to the discussion by Matsumi Mori concerning gender-based wage discrimination in Japan.
