Hospital acquisitions, parenting styles and management accounting change: an institutional perspective

Many healthcare scholars have applied institutional theories to the study of MAS change. However little attention has been devoted to Management Accounting Systems (MAS) change within groups. Kostova et al. (2008) highlight the limitations of traditional institutional frameworks in studying groups since they are characterised not only by the existence of external institutional environments but also by intra-organisational (meso-level) ones. Given this background, the research question is: how does the mesolevel institutional environment affect MAS change in healthcare groups? We use a longitudinal multiple-case study design to understand the role of headquarters in shaping local MAS change. We would expect companies to adopt similar MAS. However, we argue that the relationship between external institutions and MAS change cannot be wholly understood without taking into consideration the role of headquarters. Our analysis shows how hospitals facing the same external institutional environment implement different MAS as a consequence of different parenting styles. From a scientific perspective our article contributes to broaden traditional institutional theoretical frameworks.
