Drawing on interpretive policy analysis with its strong focus on emotions and ethnography, this chapter explores the role of emotions in institutional policy change. By applying the concept of emotionability that accounts for the concrete micro-level mechanisms through which practices of affective citizenship are realized in the context of institutional interactions, the chapter discusses the ways in which social policy changes are brought to life by interacting and relating welfare workers and welfare clients. Emotionability is therefore presented here as a real-life phenomenon accompanying policy changes and an analytical tool enabling the analysis of such changes.
