The article proposes a social network analysis of the main European capitalisms and its correspondence with an index of economic freedom. The analysis relates to two kinds of economic liberties taken from the concept of freedom formulated by Isaiah Berlin. While the first kind of freedom (negative freedom) depends on the external system (e.g. the constraints on the firm defined by the regulations), the second refers to the internal obligations within the business system itself that prevent the free exercise of business (positive freedom): specifically, the social network, in which the company is embedded. After an operationalization of the two concepts of freedom, the analysis of a comprehensive database allows us to explore the relationship between the two kinds of freedom.
