Capital punishment and deterrence: Examining the effect of executions on murder in Texas

This study tested the deterrence hypothesis in Texas, the most active execu tion jurisdiction during the modern era. Using monthly observations during 1984 through 1997, both the general relationship between executions and mur der rates and the specific relationship between executions and felony murde r rates were examined. An initial bivariate relationship between executions and murder rates proved to be spurious when appropriate control variables were included in regression models. Within a context so ideally suited for finding any potential deterrent effects, this study confirmed the results o f previous ones that failed to find any evidence of deterrence resulting fr om capital punishment.
