"Campaign Contributions Facilitate Access to Congressional Officials: A Randomized Field Experiment" (with David Broockman). American Journal of Political Science 60, no. 3 (2016): 545-558.

Argues that members of Congress grant preferential access to purported political donors over concerned constituents. Is the first experimental demonstration of the biasing role of money in politics.

"Editorial Bias in Crowd-Sourced Information" (with Peter Aronow). PLoS ONE 10, no. 9 (2015).

Employs multiple field experiments conducted on Wikipedia to show how the Wikipedia pages of incumbent U.S. Senators are biased towards positivity by systematically removing factually true yet negative facts about the Senators.

"The Female Political Career," (with Frances Rosenbluth and Dawn Teele), The World Bank and Women in Parliaments Global Forum, 2015.

Reflects survey results from 84 countries around the world designed to understand the hurdles women face in launching and sustaining successful political careers. Argues that gendered social roles and gendered social expectations shrink the pool of female political candidates even before an election begins and once in office, gendered roles and expectations continue to dog female legislators, capping ambitions as surely as they stunt their success.
