Paper on Black Politicians and Blacks’ Interests (AJPS)

David Broockman, political science graduate student at UC Berkelely, recently published a paper titled, “Black Politicians Are More Intrinsically Motivated to Advance Blacks’ Interests: A Field Experiment Manipulating Political Incentives,” in the American Journal of Political Science. The study is a field experiment and it uses data collected with Prof. Dan Butler at ISPS while Broockman was an undergraduate student at Yale.

Abstract: Why are politicians more likely to advance the interests of those of their race? I present a field experiment demonstrating that black politicians are more intrinsically motivated to advance blacks’ interests than are their counterparts. Guided by elite interviews, I emailed 6,928 U.S. state legislators from a putatively black alias asking for help signing up for state unemployment benefits. Crucially, I varied the legislators’ political incentive to respond by randomizing whether the sender purported to live within or far from each legislator’s district. While nonblack legislators were markedly less likely to respond when their political incentives to do so were diminished, black legislators typically continued to respond even when doing so promised little political reward. Black legislators thus appear substantially more intrinsically motivated to advance blacks’ interests. As political decision making is often difficult for voters to observe, intrinsically motivated descriptive representatives play a crucial role in advancing minorities’ political interests.
