Cosponsoring and Cashing In: US House Members’ Support for Punitive Immigration Policy and Financial Payoffs from the Private Prison Industry

The private prison industry is a multi-million-dollar industry that has increasingly profited from the detention of undocumented immigrants. As a government contractor, therefore, the industry has a natural interest in government decision making, including legislation that can affect its expansion into immigrant detention. In this article, we examine the relationship between campaign donations made on behalf of the private prison industry and an untested form of position taking—bill cosponsorship—in the US House of Representatives. We hypothesize the private prison industry will reward House members for taking positions that benefit the industry. We also hypothesize the private prison industry will also reward House members who incur greater political risk by taking positions out of sync with the party. To test our hypotheses, we focus on punitive immigration legislation that has the potential to increase the supply of immigrant detainees over the course of eight years. We find support for our second hypothesis, that private prison companies are more likely to reward House Democrats who cosponsor punitive immigration policies even after accounting for possible endogeneity. The findings have important implications regarding the relationship between House members and private interests.
