From public to mixed ownership in local public services provision: an empirical analysis

There is a long tradition of companies that provide local public services, such as energy distribution or solid waste collection, being strategically important for the promotion of the development of areas where they are present and having a great influence on citizens’ quality of life. This article examines the determinants of the choice of ownership structure for Italian companies that provide local public services, and the effects that this choice has on their performance. Economic and financial data at company level was merged with economic, political, financial and territorial data on the municipality with the majority of shares in it. A two-stage multinomial selection model was employed, in order to carry out the analysis with more than two alternative ownership structures and to control for endogeneity. The empirical evidence indicates that the municipality’s political and budgetary conditions matter in the choice of ownership structure. Although the computed Average Treatment Effects seem to indicate that mixed ownership increases operating efficiency, the profitability indicators provide evidence to the contrary.
