“…"Policy indexes" -those indexes that measure policies or coherent policy frameworks -have received much less methodological scrutiny in the literature on development and governance than the more popularized "concept indexes", which measure multidimensional meta-concepts such as "sustainability", "governance", "corruption", or "development", among others (see for example, Bersch & Botero, 2014;Gisselquist, 2014;Grimm, Harttgen, Klasen, & Misselhorn, 2008;Heywood & Rose, 2014;Knoll & Zloczysti, 2012;Kurtz & Schrank, 2007;McGillivray, 1991;Mitchell, 1996). Whereas concept indexes are subject to contention statistically and have received widespread attention from methodologists, policy indexes are constructed based primarily on the normative judgments (Decancq & Lugo, 2013) of policy experts or advocates.…”
