Although ethics education within the business curriculum has been receiving attention, much is unknown about the effectiveness of such education, particularly when it is integrated into the curriculum. This study looks at selected short-term effects produced by one form of integrated ethics instruction in an introductory marketing course in a graduate business MBA program in the United States. Specifically, students were introduced to an examination of consumer culture as a unifying framework to explore the ethics of decision making. As a consequence of taking the course, students are hypothesized to hold less favorable attitudes toward consumer culture (love of money, materialism, possession satisfaction index, prestige sensitivity) relative to the attitudes held at the start of the course. Interestingly, few attitudinal changes are observed. Where changes in attitudes are observed, the relationships are in the opposite direction to that hypothesized.
