Deepwater: A Computer-based Business Ethics Competitive Simulation Game by Wayne F. Buck Assistant Professor of Business Ethics Eastern Connecticut State University This version: July 11, 2012 Abstract This article explores the use and limitations of simulation games in the teaching of business ethics. This exploration consists of presenting two fundamental objections to using business ethics simulation games to teach business ethics. These objections appear to have not been previously articulated in the business ethics literature. Then I describe a competitive business ethics simulation game that I developed based on the 2012 BP Gulf oil spill and present some results from using this simulation in an undergraduate business ethics course over the past year and a half. Key words: business ethics, simulation games, teaching business ethics, BP oil spill Contact: buckw@easternct.edu (860) 465-0107
