Resumen de Evaluating the effectiveness of the Spanish police force through data envelopment analysis

Isabel María García Sánchez

• The aim of this paper is to evaluate the level of effectiveness of the National Police Force in Spain, attempting to show the possibilities that the Data Envelopment Analysis technique offers in this field. Furthermore, we have implemented a two-stage procedure which uses econometric methods to estimate the set of variables which will explain the performance of effective units. The results of our analysis show that there is a high level of investigative effectiveness, which decreases regarding coercive and overall effectiveness. This indicates that although there is logic in the cases solved and the culprits arrested, this cannot be extended, given the level of offences, to the number of cases solved, and to a lesser degree to those arrested for them. The units which are most effective overall are characterized by the solving of crimes against the right to sexual freedom and indemnity and by the arrest of a high percentage of those guilty of other offences.
