This paper analyzes the impact of intra-household bargaining on the labor supply of heterosexual couples with different divisions of domestic work. The research aims to compare the decision-making process in families with traditional and egalitarian gender role attitudes toward the division of domestic work. The collective model of labor supply with distribution factors is estimated using data from Uruguay from the year 2019. The findings indicate that couples of all types are sensitive to bargaining power shifts, as measured by the education and non-labor income gaps between partners and the type of partnership (marriage vs. cohabitation). These results suggest that households with a more egalitarian division of domestic work tend to assign a larger share of non-labor income to women after the negotiation process, highlighting the significant role of gender norms and intra-household dynamics in determining labor supply decisions, with key policy implications for promoting gender equality in labor markets.
