Prerequisites: master's level microeconomics course (e.g., 90-709, 90-710)and master's level electronic commerce course (e.g., 95-730) All organizations are faced with the task of achieving their goals in the face of external obstacles and pressures. An electronic commerce firm's (e-firm's) approach to these challenges constitutes its strategy. In this course we will use the tools of game theory to develop ways of thinking strategically about the challenges e-firms face. This will include defining the e-firm's & quot; value net & quot; of customers, competitors, complementors, regulators, and suppliers, analyzing an organization's added value and how that depends on competitors and complementors, and designing strategies taking account of these factors. Instruction will consist of lectures combined with cases. We will also play & quot; The e-Strategy Game & quot; -- a series of computer simulations of competition among e-firms that sell physical and information goods to businesses and consumers.
