Despite the widespread agreement that the ontology of the marketing discipl
ine is exchange, marketing ethics researchers have largely adopted a monadi
c viewpoint of ethical decision making. In this research, an interactionist
approach is adopted in order to introduce a dyadic perspective of un/ethic
al decision making. The dyadic model includes each channel member's individ
ual, situational and decision process factors linked by relationalism, an e
merging paradigm in marketing channels. Relationalism is represented as a d
iscriminating variable between perceived ethical dilemma and decision behav
iour. Finally, a number of theoretical propositions are presented and futur
e research directions are discussed.
