“…These taxonomies provided analysts a framework for describing and assessing the ways in which governments connect policy goals and means in their effort to improve outcomes which over time have fostered the emergence of a 'tools approach' to understanding problems (Hood, 2007). Recent research has focused not only on choice of individual tools but also how they are assembled together as 'policy mixes' or 'portfolios' to maximise complementarities amongst and between tools (Borras and Edquist, 2013; Flanagan, Uyarra, & Laranja, 2011;Howlett & Del Rio, 2015;Mohnen and Roller, 2005;Schaffrin, Sewerin, & Seubert, 2014;Sovacool, 2008); issues relating to policy coordination (Jordan & Lenschow, 2010;Peters, 2015Peters, , 2018; policy coherence and consistency of these mixes (Howlett & Rayner, 2007;Kivimaa and Virkamaki, 2014;Rogge & Reichardt, 2016); how they are sequenced and layered (Howlett, 2019); the 'intensity', and explicitness with which they affect change (Thomann, 2018;Howlett, 2018) and criteria to evaluate them (Howlett, Capano, & Ramesh, 2018;Capano & Woo, 2018;Mukherjee & Howlett, 2018;del Rio, 2018;Bali, Capano and Ramesh, Forthcoming). These studies go beyond describing broad institutional choices used to organise a sector or policy styles and implementation preferences of governments (Bemelmans-Videc, 1998;Hood, 1983;Linder & Peters, 1989;Salamon, 2002;Trebilcock et al, 1982).…”
