Publications

"The Causal Effects of Elite Position-Taking on Voter Attitudes: Field Experiments with Elite Communication" American Journal of Political Science 61, no. 1 (2017): 208-221.

Tests theories of how politicians are constrained or unconstrained by, and interact with, public opinion. 

"Do Female Politicians Empower Women to Vote or Run for Office? A Regression Discontinuity Approach" Electoral Studies 34 (2014): 190-204.

Finds that the election of additional women in competitive US state legislative elections has no discernible causal effects on other women's political participation at the mass or elite levels. 

"Campaign Contributions Facilitate Access to Congressional Officials: A Randomized Field Experiment" (with Joshua Kalla). 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.

"What Politicians Believe about Their Constituents: Asymmetric Misperceptions and Prospects for Constituency Control," (with Christopher Skovron), University of California, Berkeley, February 28, 2013.
Shows that politicians are typically ignorant of constituency opinion and salient issues in their districts and, moreover, typically overestimate the conservatism of their constituents. Conservative politicians’ errors are particularly egregious, overestimating their constituents’ conservatism by around 20 percentage points on average.
"Black Politicians are More Intrinsically Motivated to Advance Blacks’ Interests" American Journal of Political Science 57, no. 3 (2013): 521-536.

Employs a unique experimental design to demonstrate that black politicians are more intrinsically motivated to represent blacks’ interests than are whites. When the incentives of politicians to respond to a putative request from a black individual are experimentally reduced, black politicians generally continue to provide representation though white politicians generally do not.
