“…Knill, Schulze, and Tosun (2012) added a fourth category which denotes the scope of a policy instrument, that is, how it governs its target groups. These four categories have been used to empirically assess how policies -in terms of their density and intensity -have expanded and/ or contracted over time (Bauer, Green-Pedersen, Héritier, & Jordan, 2012;Jordan, Bauer, & Green-Pedersen, 2013;Knill et al, 2012;Schaffrin, Sewerin, & Seubert, 2014).…”
