The Rodotà Commission has proposed an innovative reform of the Italian Civil Code concerning the types of property rights. It introduces the category of common goods, intended as «those goods which are functional to the enjoyment of human rights»; these have to be withdrawn from the market and managed by publicly-owned entities. This article uses the economic theory to provide a critical assessment of this approach. Despite many similarities, the economic approach diverges substantially, especially as far as management is concerned. We suggest that the new theory of collective action may provide a common ground for the analysis. Moreover, we argue that the role of economic analysis is to draw attention onto the many constraints that bind it.
