“…As Binderkrantz, Pedersen, and Beyers (2016) stress, access is multidimensional, so it has to be evaluated with respect to the specific political arena(s) an actor enters. The theory and empirical testing in this article covers access to both the parliamentary and media arenas, as important forms of inside and outside access, where interest groups enjoy exclusive contact with relevant gatekeepers (Binderkrantz, Pedersen, et al, 2016;Halpin & Fraussen, 2017) and receive the opportunity to transmit constituency information. The article adds to important existing work across arenas, (Beyers, 2004;Binderkrantz et al, 2015;Boehmke, Gailmard, & Patty, 2013;Halpin, Baxter, & MacLeod, 2012) by testing a venue-specific theory on how cooperation in umbrella organizations affects access.…”
