The best work being done on the explosion in incarceration is by Marie Gottschalk, a professor at UPenn. She's done two great books on what has driven the increase in incarceration, and how the drivers of incarceration have changed over time (e.g. the War on Drugs was a major driver in the 1980s, but faded in importance relative to three-strikes and zero tolerance laws in the 90s).
