We investigate behavioral responses of judges and prosecutors to more severe punishments by analyzing the effects of Truth-in-Sentencing (TIS) laws in a large sample of individual criminal cases. We use the "State Court Processing Statistics: Felony Defendants in Large Urban counties", an individual level dataset on approximately 100,000 criminal cases in state courts.
Our evaluation of the impacts of the TIS laws produced consistent evidence on several channels of behavioral responses to longer effective prison sentences in the criminal justice process.
