Jennifer Doleac

Doleac has written extensively prisoner reentry. Prisoner reentry is a considerable challenge in the United States due to the ubiquity of background checks and the myriad of obstacles prisoners face reentering the labor force upon release. An increasingly popular policy at the federal, state and municipality level is the "ban the box" initiative. Employers often will ask applicants for jobs if they have any prior arrests or convictions by checking Yes or No on a "box". The ban the box initiative are laws, oftentimes at the city level, banning employers' right to ask this information of applicants during the earliest stages of the application process. In her most-cited publication, a 2018 article published in the Journal of Labor Economics, Doleac and Benjamin Hansen from the University of Oregon found that these laws had unintended consequences on the hiring of low skill minorities.[11] The authors found that ban the box policies lowered the chances of employment by 5 percent for young, low-skilled black men and almost 3 percent for young, low-skilled Hispanic men. The authors argue that this effect was caused by rampant statistical discrimination in labor markets. Without information on a candidate's criminal history, employers make extreme racially biased assumptions that the applicant is similar to his or her demographic. Thus seeing a black applicant, even one without a criminal history, the firm "fills in" the missing information by assuming he or she is like the group average, and thus is more likely to believe the applicant has a criminal history, even when they do not.

In addition to conducting her own research, Doleac synthesizes and critiques other studies of crime and criminology, highlighting results supported by solid empirical work and by natural experiments that support causal relationships.[4] She has testified about the impact of Ban-the-box policies on hiring before the U.S. House Committee on Oversight and Government Reform[12] and about effective crime-reduction policies before the New Mexico Legislature.[13]

Doleac hosts the Probable Causation podcast focusing on law, economics and crime.[4]

In 2018, Doleac, then a Brookings expert, released a study under Brookings along with Anita Mukherjee and Molly Schnell which claimed that harm reduction (an evidence-based approach focused on maximizing health) does not work. Doleac and her co-authors claimed that syringe exchange programs and naloxone distribution would worsen addiction.[14] However, the claims were disputed by public health officials who argued that the results of Doleac's finding go against previous research on harm reduction. Doleac and her co-authors, it was claimed, only focused on economic literature on harm reduction and ignored public health research. In response to the criticism, Doleac released a statement through Brookings where she said the public health discipline was filled with researchers who "collectively have so little understanding of rigorous research methods". In response to Doleac's comments, Brookings released a statement where the institute said that it "does not take positions on issues, nor does [it] endorse Doleac's response to the criticism and feedback she received".[15]
