This work discusses the issue on how to include data about property and violent crimes in the production technology for the assessment of police technical efficiency. It applies recent advances in Directional Distances and Nonparametric Estimators. We claim that crime is an external variable not under the control of the decision units in view of the fact that it is exogenously determined. The results from the Conditional Directional Distance Analysis can be relevant to cities with high property misdemeanors and homicide rates.

An appropriate access charges regime represents the basis for implementing an open market and for guaranteeing fair competition in the rail sector. In accordance with the recent European and national legislations, the Italian rail infrastructure manager has lately presented a new charges scheme with a better cost orientation and a deeper market segmentation based on the ability to pay. This paper describes and compares the new and the previous regimes, presenting a case study on selected Italian corridors.
