The for-profit prison industry sells itself as a cost-effective option for cash-strapped states, but according to a new study from the University of Wisconsin, privatized prisons are keeping inmates locked up longer in order to boost profits.
Researcher Anita Mukherjee studied eight years* of data from Mississippi, which has one of the highest incarceration rates in the country, and found that private prisons there doled out twice the amount of infractions against inmates, lengthening their sentences by an average of two or three months. The extra time, Mukherjee found, adds up to an increase of about $3,000 in additional costs per prisoner. Mukherjee also noted that inmates housed in private prisons were more likely to wind up back in the system after being released—despite industry claims of lower recidivism rates.
The study, which compares length of stays in private and public prisons, is not the first to highlight strategies undertaken by the private prison industry to raise returns for stockholders. Last year, Christopher Petrella, a researcher at the University of California-Berkeley, accused the Corrections Corporation of America of including provisions in its contracts with governments to keep the most costly inmates—those with health issues—from being transferred to its prisons. Through open records requests, Petrella found there were 14 different exclusion criteria, including disabled or elderly inmates, those who were HIV-positive, or anyone with "sensitive medical conditions and/or high risk diagnoses."
