The decision to work is an important yet understudied facet of women’s economic empowerment. This study explores the relationship between married women’s agency over the decision to work, workforce participation, and control over financial resources, using cross-sectional survey data collected in 2022 in India’s three most populous states: Bihar, Uttar Pradesh, and Maharashtra. Employing logistic regression, inverse probability weighting, and partial identification approaches, we demonstrate that married women in all three states are significantly more likely to engage in paid work when they alone have the final say over the decision to work, compared to when their spouse is the primary decision-maker. We also find that sole decision-making about paid work is positively related to married women’s control over money in Bihar and Maharashtra, and with savings and remittances in Maharashtra. In Maharashtra, women who jointly decide about employment with their spouse are also more likely to work than women whose husbands are the sole decision-makers. Joint decision-making is positively associated with women’s control over money in all three states. Our study highlights work-related agency as an important pathway to married women’s economic opportunities and inclusion in India, and is among the first to empirically examine the relationship between women’s work-related decision-making and economic outcomes. These results align with existing evidence on the positive relationship between women’s household bargaining power and health and human capital outcomes, and offer support for designing programmes to promote women’s participation in the workforce.
