Ownership or procurement, which matters? exploring asymmetries in local public transportation in Italy through a semi-parametric approach

The local public transportation (LPT) system is crucial for the growth and competitiveness of regions. The efficiency of service providers and the chosen procurement system significantly influence the LPT system's operational dynamics. This study combines an analysis of service contract determinants with a comprehensive examination of company ownership impacts and LPT service procurement dynamics in major Italian cities. Using a GAMLSS (Generalized Additive Models for Location, Shape, and Scale) approach, the study identifies key factors influencing contract outcomes. This study reveals the complex interplay of cost factors, ownership models, and geographical disparities, offering valuable insights for policymakers and public transportation professionals.
