That is the title of the job market paper of Mitch Downey, of UCSD, the subtitle is “Congressional Elections and Union Officer Prosecutions,” and here is the abstract:
Democratic societies rely on fair judicial systems and competitive political systems. If politicians can control criminal investigations of influential groups and use them to undermine political opponents and protect supporters, it subverts these systems. I test whether prosecutions of politically active labor unions respond to Congressional election outcomes. I use novel data on federal indictments, campaign contributions to measure support, and a regression discontinuity to recover causal effects. I find that union officers are 67% more likely to be indicted when the candidate their union supported barely loses. These indictments weaken unions’ ability to influence politics, making reelection more difficult for union-supported Representatives and easier for the union-opposed. As such, the discontinuity might reflect reduced indictments to protect election winners’ union supporters or increased indictments to target winners’ union opponents. A series of analyses suggest it includes both. The results show that US politicians manipulate the justice system to maintain power.
His other papers, at the above link, are interesting too, covering voting, labor market frictions, and also the political economy of Afghanistan.
