“…In this case, membership is expected to lead individuals to develop 'new' values through interactions with co-members. 2 Given the importance of formal and informal institutions for governing people's behaviour (e.g., North, 1990;Thelen, 1999) and earlier findings linking the institutional environment to the development of specific types of voluntary associations (e.g., Berman, 1997;Schofer & Fourcade-Gourinchas, 2001;Kääriäinen & Lehtonen, 2006), it is surprising that both lines of argument ignore the socio-political and institutional environment within which the individual and the association exist.
