In a Bureau of Prisons (BOP) funded study by Doug McDonald. and Scott Camp, known as the "Taft Studies," privatized prisons were compared side-to-side with the public prisons on economic, performance, and quality of life for the prisoner scales. The study found that in a trade off for allowing prisons to be more cheaply run and operated, the degree to which prisoners are reformed goes down. Because the privatized prisons are so much larger than the public-run prisons, they were subject to economies of scale. Privatized prisons run on business models, promoting more an efficient, accountable, lower cost alternative to decrease government spending on incarceration.
