“…In accordance with the outlined role of MAS at micro and macro (internal/external) level and its usefulness in the healthcare systems, the paper strives to present the significance of MAS in a socio-economic context and highlight the research needs concerning the various aspects of MAS. The neglected function of cost accounting within MAS in public sector organisations (Jovanovi c & Dragija, 2018;Lutilsky et al, 2012;Spekle & Verbeeten, 2014) have been perceived as an administrative or even bureaucratic activity. Based on the resource-based view (RBV) in the strategic management theory of public organisations, which observes the interior structure of the organisation, as well as its resources and capabilities (Arbab Kash, Spaulding, Gamm, & Johnson, 2014;Bryson, Ackermann, & Eden, 2007;Rosenberg Hansen & Ferlie, 2016), the paper presents the insight into the development stage of cost accounting systems in Slovenian and Croatian hospitals.…”
