The article is motivated by two related research questions about research activity in the Operations Research / Management Science / Operations Management (OR/MS/OM) and Finance disciplines. highlights the potential for a wider collaboration among researchers, particularly Finance academics exploring how various OR/MS/OM techniques can be adopted or adapted. We discover that the ranking of OR/MS/OM journals is determined more by the extent they are cited in other disciplines, and observe a gradual rise in self-perpetuating behavior in OR/MS/OM.
