“…At the interest group level, research has focused on the effect of group type, pointing to differences in access between economic and public interests (Beyers, 2004;Binderkrantz, Bonafont, et al, 2016;Binderkrantz et al, 2015;Boehmke et al, 2013;Eising, 2007;Halpin et al, 2012;Rasmussen & Gross, 2015). Relatedly, studies have emphasized the importance of resources for securing access, including informational resources (Chalmers, 2013;De Bruycker, 2016;Tallberg et al, 2015), financial resources (Eising, 2007;Fraussen et al, 2015;Rasmussen & Gross, 2015), and support resources in form of the size of individual membership (Fraussen et al, 2015;Fraussen & Beyers, 2016).…”
