A 2015 study from the University of Wisconsin found that private prisons in Mississippi (which has one of the highest incarceration rates in the state) handed down more violations and increased inmate sentences more frequently than their state counterparts, elongating the amount of time a citizen spends in a prison bed and, in turn, jacking up profits for the facility. States may want to consider increased monitoring to prevent excessive violations to keep costs in line or having contracts that don’t just reward operators for filling beds but require them to produce outcomes such as reduced rates of recidivism,” observed Anita Mukherjee, the study’s author.
