Update: The National Employment Law Project has responded to these studies with a critique that we cover here.
Ban-the-box policies have become popular in recent years as a way of minimizing discrimination based on criminal history, and have been adopted by 24 states, the federal government, and a number private companies. But until recently there has been little hard data available about the general effect of those policies on employment opportunities. A number of recent studies have begun to fill that gap, and the results have been disturbing. The consensus seems to be that while banning the box does enhance the employment prospects of those with criminal records, it also encourages employers to fall back on more general racial stereotypes about criminal history without the “box” to confirm or deny it.
Most recently, a multi-year field study by Amanda Agan (Princeton University) and Sonja Starr (University of Michigan Law School) found that although banning the box made it more likely that individuals with criminal records would receive call-backs from prospective employers, it dramatically increased the gap in call-backs between black and white applicants. Employer responses to over 15,000 fictitious job applications sent to New York and New Jersey employers after ban-the-box policies took effect showed that black applicants received 45% fewer callbacks than white applicants, up from a 7% differential before the new policy took effect:
