Collectively, the purpose of the three papers included in this dissertation was to provide empirical evidence on the contextual factors that influence hospital utilization of services of group purchasing organizations and how utilization of group purchasing organizations impacts hospitals’ financial performance. The findings of these studies are important both to researchers and to managers as it sheds light on the relationship between hospitals and group purchasing organizations. The results of this dissertation suggest that better financial performance is associated with hospital utilization of group purchasing organizations. Additionally, some measures of environmental munificence and dynamism are associated with hospital utilization of group purchasing organizations. Specifically, the association seemed more consistent across less munificent and more dynamic environments. Taken together, the findings of these studies will be beneficial to hospital leaders as they make decisions about strategies on group purchasing organizations.
