Stop, Collaborate, and Listen: Women's Collaboration in US State Legislatures

Collaboration plays a key role in crafting good public policy. We use a novel data set of over 140,000 pieces of legislation considered in US state legislatures in 2015 to examine the factors associated with women's collaboration with each other. We articulate a theory that women's collaboration arises from opportunity structures, dictated by an interaction of individual and institutional characteristics. Examining the effect of a combination of characteristics, we find support for an interactive view of institutions, where women's caucuses accelerate collaboration in Democratic‐controlled bodies and as the share of women increases. Collaboration between women also continues in the face of increased polarization in the presence of a caucus, but not absent one. Our findings speak to the long‐term consequences of electing women to political office, the importance of institutions and organizations in shaping legislative behavior, and the institutionalization of gender in politics.
