There is an increasing need for business students to be taught the ability to think through ethical dilemmas faced by corporations conducting business on a global scale. This article describes a multiplayer online simulation game, ISLAND TELECOM, that exposes students to ethical dilemmas in international business. Through role playing and perspective taking, the authors wanted students to actively work through problems related to both ethics and corporate social responsibility. Qualitative analysis of simulation data demonstrated that students were successful in perspective taking, they considered trade-offs between profitability and social responsibility, and they were able to come up with creative solutions to difficult trade-offs.
