In this paper, we evaluate the efficiency of state police services in the continental United States using a multiple-stage data envelopment analysis model. Using multiple inputs and multiple outputs to characterize police service provision, technical and scale efficiency are calculated for the...

Data envelopment analysis was introduced as a nonparametric linear programming estimator to estimate the production frontier and technical efficiency of observed production units. Allowing multiple inputs and multiple outputs, the approach can be considered a nonparametric quantile regression...
