“…A large number of studies utilize surveys to better understand the role of interest groups in the policy process (Hoefer, 1996;Cox and Vass, 2000;Dalton et al, 2003;Heaney, 2006;Fried, 2007;Reenock and Gerber, 2007;Hall and Miler, 2008;McKay, 2012) including the role groups play in shaping legislative behavior (Wright, 1990), and the influence of interest groups generally (Binderkrantz, 2005;Chalmers, 2011;Klüver, 2012a) or within particular policy areas (Goldsmith, 2002). Several studies use surveys to shed light onto how variations in institutional structure affect organizational behavior (Eising, 2004;Reenock and Gerber, 2007;Tsujinaka and Pekkanen, 2007;Klüver, 2010;Constantelos, 2011;Pleines, 2011) and to better understand groups' relationships and interactions with bureaucratic institutions, political decision-makers or governmental bodies (Braun, 2012a, b;Klüver, 2012b;The LSE GV314 Group, 2012;Rasmussen, 2012;Chalmers, 2013).…”
