Only two OECD countries continue to exhibit an M-shaped curve of female labor force participation across the life cycle: Japan and South Korea. In this seminar, Mary Brinton analyzes how labor market structure and workplace norms influence this pattern. Her analysis draws on data from over 160 in-depth interviews with highly-educated Japanese and Korean men and women of childbearing age, and demonstrates how working conditions exert a powerful influence on gendered patterns of behavior at home and in the labor market.
