After decades of “tough on crime” policies, the number of ex-offenders in the USA has increased dramatically. Felony convictions limit ex-offenders’ opportunities in the labor market. In an effort to reduce these barriers, many US jurisdictions have implemented closed records policies such as “ban the box.” By limiting employers’ access to applicants’ criminal history records, these policies attempt to eliminate the discrimination that qualified ex-offenders face in the labor market because of the stigma attached to a criminal conviction. These policies have been under scrutiny because of the possible ramifications limiting employers’ access to labor market information might cause. Drawing upon Merton’s theory of “unintended consequences of purposive social action” (1936), this paper investigates the motivations behind the decision to implement and enforce closed records’ policies and the existing body of knowledge on ex-offender barriers to employment available to social agents and analyzes the potential ramifications.
