Rational Choice and Inmate Disputes over Phone Use on Rikers Island

Abstract

Abstract: In an attempt to reduce the high costs of illicit inmate telephone use, a high-security, computerized phone system/or Inmates was introduced on Rikers Island in 1993. A Jew months after implementation, correction officers observed that the system had the beneficial side effect of reducing fights over phone use. This paper confirms the anecdotal evidence, finding that the new phone system reduced both phone costs and inmate violence related to phone use by 50%. There was little evidence of displacement to other forms of violence. These results demonstrate that violent crime may often be precipitated by sltuatlonalfactors and may be prevented by reducing opportunities for disputes
