“…6 Regarding social capital, in the literature there are different approaches to its measurement, as social capital is a multifaceted concept (Dasgupta and Serageldin, 2000;Paldam, 2000;Christoforou, 2013). Conceptually, social capital has been associated, for instance, with trust towards other people and institutions, and firm performance (Fukuyama, 1995;Glaeser et al, 2000;Guiso et al, 2008;Akçomak and Ter Weel, 2009;Lins et al, 2017;Stiglitz et al 2018, Chapter 10); membership in groups, networks and voluntary associations (Putnam et al, 1994;Alesina and La Ferrara, 2002;Sobel, 2002); membership and trust (Lochner et al 2003;Vincens et al, 2018); membership, trust, and norms of reciprocity (Putnam, 2000;Bigoni et al, 2016). Operationally, higher voter turnout and association density are hypothesised to capture civic involvement and participation in community decision making, while voluntary donations capture the strength of intermediate social structures (e.g., Putnam et al, 1994;Putnam, 2000;Cartocci, 2007;Buonanno et al, 2009).…”
