This course in relation to:
-M&S 431: Core strategy course
-MECN 441: Competitive strategy and Industrial Structures
Management and Strategy MS 431 M&S 431 was about describing and classifyingcompetitive forces in
an industry (e.g., Five Forces)
M&S 431 relies on loose verbal applications of microeconomic ideas
This course, MECN 430, is about understanding thefundamental economic drivers and mechanisms
underlying these forces
Competitive Strategy and Industrial Structures, MECN 441 Uses richer cases to develop deeper, more detailed understanding of
forces shaping strategic interaction between firms in concentratedindustries

2. Cost: You will learn how to identify the categories of costs that
are relevant for critical business decisions such as pricing, newmarket entry, and capacity abandonment
3. Government interventions: You will be able to constructmodels of how govt policies shape market interactions and thedistribution of value
4. Profit-maximizing pricing decisions: You will learn how optimalpricing should balance cost and demand fundamentals
