Why Female Politicians Are More Effective

Some dubbed it "The Year of the Woman." But despite "mama grizzly" talk and a crop of high-profile female candidates, last year's elections resulted in no net additions to the female ranks of the Senate and, for the first time since 1978, a net loss in the House. In fact, more than 90 years after the first woman was elected to Congress, female politicians still hold less than a fifth of all national seats, and do only slightly better at the state level. But that's more than just a blow for diversity and equality, according to a forthcoming study in the American Journal of Political Science—because women also rank as the most effective lawmakers in the land.

The research is the first to compare the performance of male and female politicians nationally, and it finds that female members of the House rout their male counterparts in both pulling pork and shaping policy. Between 1984 and 2004, women won their home districts an average of $49 million more per year than their male counterparts (a finding that held regardless of party, geography, committee position, tenure in office, or margin of victory). The spending jump was found within districts, too, when women moved into seats previously occupied by men, and the cash was for projects across the spectrum, not just "women's issues."

A similar performance gap showed up in policy: Women sponsored more bills (an average of three more per Congress), co-sponsored more bills (an average of 26 more per Congress), and attracted a greater number of co-sponsors than their colleagues who use the other restroom. These new laws driven by women were not only enacted—they were popular. In a pair of additional working papers, led by Ohio State political scientists Craig Volden and Alan Wiseman, researchers tracked every bill introduced between 1981 and 2009, and found that those sponsored by women survived deeper into the legislative process, garnered more press attention, and were more likely to be deemed "important" overall. All of which leads the authors of the AJPS paper, University of Chicago Public Policy Professor Christopher Berry and his student and Stanford doctoral candidate Sarah Anzia, to conclude that it’s the women themselves—specifically, their skills at "logrolling, agenda-setting, coalition building, and other deal-making activities"— that are responsible for the gender-performance divide.

So are women just innately better politicians? Probably not. More likely, say Berry and Anzia, female politicians are better than men because, as in other fields, they simply have to be. More than 90 years after the first woman was elected to Congress, female politicians still hold less than a fifth of all national seats, and do only slightly better at the state level. In order to overcome lingering bias against women in leadership positions, those women must work that much harder to be seen as equals.
