La reputazione della Pubblica Amministrazione come bene comune: definizione, declinazione e tutela.

The present thesis deals with the reputation of the Public Administration as an intangible common good, analyzing its relevance in the Italian legal system and investigating the forms of protection. After reviewing the attempts to define the concepts of reputation and the common good, both in economic sciences and in legal sciences, the reasons that lead to qualifying public reputation as an intangible common good, bringing a series of advantages in the public interest, are illustrated. The research then takes shape with the illustration of two reputational systems pertaining to the public administration: the Evaluation of the quality of Italian research (VQR) and the qualification of the procuring entities, highlighting their strengths and weaknesses. The research ends with the analysis of the forms of protection of public reputation as a common good, analyzing, in particular, the damage to the image of the P.A. and the administrative class action.
