This contribution explores the history of women and feminism in the Union for Radical Political Economics (URPE) using concepts from feminist radical political economy. A feminist approach changes the categories of economic analysis to offer a new interpretation of an older history: the formation of the Women’s Caucus. I reread the early history of the feminist project in economics through the lens of social reproduction to understand the influence of life experience on practice, particularly on the 1971 women’s walkout during a URPE conference, and on economic theory. Highlighting women’s multiple roles, as graduate students, mothers, wives, girlfriends, and/or caregivers – but ultimately as women – reveals social reproduction as a site of radical politics and demonstrates the importance of reproductive labor for understanding solidarity. In doing so, the analysis provides an example of how a feminist perspective contributes uniquely to economics.
