Controlling for a variety of state characteristics, we investigate the impact of the execution, commutation, and removal rates, homicide arrest rate, sentencing rate, imprisonment rate, and prison death rate on the rate of homicide. The models are estimated in a number of different forms, controlling for state fixed effects, common time trends, and state-specific time trends. We find a significant relationship among the execution, removal, and commutation rates and the rate of homicide. Each additional execution decreases homicides by about five, and each additional commutation increases homicides by the same amount, while one additional removal from death row generates one additional homicide.
