The course aims at providing an undergraduate-level introduction to understand why firms exist and their role and function in modern economic systems. If the creation of economic and non-economic value for key stakeholders as well as competitive advantage is at the key of any business organization, the primary goals for students is to understand: 1) how they are structured; 2) what are the key strategic choices that firms make and 3) how can firms be effectively led. Such an understanding also requires that we look at different levels within the organization. I emphasize both the behavioral processes (individual effectiveness, social interaction, groups, and teams) and the macro-level such as organizational design, organizational change, people management, and organizational culture.
