Informations and abstract
Keywords: differentiated autonomy, tax autonomy, regional legislation, policy evaluation.
The essay focuses on the implementation of the art. 116, paragraph 3, of the Constitution, and emphasizes how the negotiation of a differentiated autonomy for Regions Emilia-Romagna, Lombardia and Veneto has missed, so far, the opportunity to test a new approach to some relevant policies. Three are the issues taken into account: the authorization for Regions concerned to derogate from the provisions of national legislation, the implementation of a regional tax autonomy and the role of national government in evaluating the outcomes of the devolution.
