TY - RPRT AU - Brenøe, Anne Ardila TI - Origins of Gender Norms: Sibling Gender Composition and Women's Choice of Occupation and Partner PY - 2018/Jul/ PB - Institute of Labor Economics (IZA) CY - Bonn T2 - IZA Discussion Paper IS - 11692 UR - https://www.iza.org/index.php/publications/dp11692 AB - I examine how one central aspect of the childhood family environment – sibling gender composition – affects women's gender conformity, measured through their choice of occupation and partner. Using Danish administrative data, I causally estimate the effect of having a second-born brother relative to a sister for first-born women. The results show that women with a brother acquire more traditional gender norms with negative consequences for their labor earnings. I provide evidence of increased gender-specialized parenting in families with mixed-sex children, suggesting a stronger transmission of traditional gender norms. Finally, I find indications of persistent effects to the next generation of girls. KW - occupational choice KW - sibling gender KW - gender identity KW - family formation ER -
