This study examines the relationships between perceived ethical problem and ethical intentions of marketing managers. In addition, the moderating effect of locus of control on this relationship is also probed. Several hypotheses were developed after reviewing the relevant literature. A field research is conducted to collect data from marketing managers working for small enterprises located in Balikesir province of Turkey. Data analyses revealed that locus of control moderates the relationships between perceived ethical problem and ethical intentions. Theoretical and managerial implications of the findings are discussed. (C) 2013 The Authors. Published by Elsevier Ltd. Open access under CC BY-NC-ND license.
