Interdependence Effects in Mixed-Superposition Electoral Systems: An Empirical Test on Women's Participation in Sub-national Elections

Mixed-superposition electoral systems, while devoid of compensatory mechanisms interconnecting their proportional and non-proportional sections, may create effective linkages that exert some impact upon the behaviour of political parties. This article examines the resulting interdependence effects with respect to women's electoral participation and legislative representation. It is hypothesized that if political parties embrace the logic of ticket-balancing when forming their candidate lists in the proportional representation sections of elections, they become more willing to nominate female candidates in majoritarian districts, which creates an important interdependence effect that ultimately contributes to the increased levels of women's representation. This hypothesis is empirically tested on a sample of 139 sub-national elections held in Russia in 2003–2011, with some additional information derived from the results of 81 previously held elections. The statistical analysis confirms the presence of interdependence effects with respect to women's political participation. The principal contextual factor that intermediates the observed effects is political regime. It is shown that electoral authoritarianism mitigates the interdependence effects of mixed-superposition electoral systems.
