This study tests the hypothesis that collective descriptive representation has important benefits for strengthening and legitimizing democratic society. Specifically, we test whether increased proportions of collective female descriptive representation in the statehouse and the presence of a female state executive are important to female citizens' attitudes toward government responsiveness, or external efficacy. We hypothesize that an increase in female collective descriptive representation in the legislative and state executive branches of government will increase female citizens' external efficacy but will be unimportant to males. We pooled American National Election Studies (ANES) data from 1988 to 1998 and used ordered probit techniques to test the hypothesis. In addition to our main independent variable of interest, our model includes state political culture, dyadic descriptive representation, dyadic substantive representation, sociodemographics, political participation, strength of partisanship, and electoral dummy variables as controls. Our results confirm that higher levels of collective female descriptive representation promote higher values of external efficacy for female citizens, suggesting that collective female descriptive representation has important benefits to a democratic society. E xternal political efficacy is the individual perception that governmental authorities and institutions are responsive to citizen influence
