“…The focus, instead, has been on two main conceptualizations of social capital: civicness and network endowment and use. Scholars have concentrated on the mechanisms of accumulation of these different types of social capital (Alesina and La Ferrara, 2002, Glaeser et al, 2002and de Blasio and Nuzzo, 2010 and on the effects of these on economic variables (for example, Saxenian, 1994, Putnam, 1995, Knack and Keefer, 1997, Hall and Jones, 1999and Sacco and Vanin, 2000. The results of the empirical literature can be summarized as follows (see Righi and Scalise, 2013): increasing civicness always turns out to be beneficial for economic growth, while evaluating the impact of larger and denser networks requires considering the balance between the positive and negative externalities generated, some of which would generate a negligible amount of negative externalities spurring economic development, while others could even be detrimental.…”
