The ethics issue has been receiving massive attention of today’s managers due to the publicized scandals and cases of fraud, bankruptcy and others. For managerial convenience numerous ethical decision making models were proposed by researchers, but six models are widely accepted by ethics based practitioners (Ferrell, Fraedrich & Ferrell, 2008). Each model has unique characteristics, which enhances understanding about ethical dilemma. This paper reviewed the relevant literature and utilized seven models: (Kelly & Elm, 2003; Jones, 1991; Ferrell, Gresham & Fraedrich, 1989; Hunt & Vitell, 1986; Trevino, 1986; Ferrell & Gresham, 1985; Kohlberg, 1969) and then cultivated ethical decision-making model for Thai context. In addition, the authors also reviewed the literature on Thai culture and focused on Buddhist philosophy, beliefs, values and norms of Thai people. Finally, the Seven ethical decision making models and Buddhist philosophy were integrated together to propose a model for ethical decision making for Thai organization.
