“…Literatures addressing the origin of policy ideas, for example, how ideas are learned and adopted by political and policy practitioners, and through what mechanisms and processes they transfer and diffuse, see agential and institutional learning as a key driver of change (Bennett & Howlett, ; Cao, ; Dobbin, Simmons, & Garrett, ; Drezner, ; Elkins & Simmons, ; Gilardi, , ; Meseguer & Gilardi, ; Voegtle, Knill, & Dobbins, ). Several interrelated processes and constituencies are identified, including epistemic communities such as specialist knowledge practitioners who communicate through discrete networks and collectively forge ideational changes in relation to policy thinking, institutional agendas, and goals which then filter into domestic institutional contexts (Blanco, Lowndes, & Pratchett, ; Grossmann, ); or exogenous processes such as international standards regimes, market access considerations or interstate competitive pressures which create new problems and agendas that contribute to policy and institutional change (standards adoption, regulatory reform, or adherence to “best‐practice”/rankings) (Carroll & Jarvis, ; Dolowitz & Marsh, , ; Jarvis, , ). Change thus arises through multidirectional processes that inform policy thinking, agendas, and preferences.…”
