This course aims to develop students' knowledge of theories in marketing. The perspective in this course is that marketing does not depend on a pure or single disciplinary base. Instead, it may be regarded as an applied social science or synthetic discipline in the original sense of the process or result of building up separate elements, especially ideas, into a connected whole or into a theory or system. It follows that if one wishes to be qualified to practice the profession of marketing then one should know and understand the sources of the original ideas and theories on which it is founded. The course focuses on essential theories in marketing. The course has a theoretical approach rather than being descriptive or normative.
