Firm Strategy and Competition

SAM15 Firm Strategy and Competition

Spring 2024

Autumn 2024
  • Topics

    The course focuses on how game theory can be applied to understand and predict firms' behavior and strategic interaction between firms. During the course the students will be introduced to various cases focusing on specific industries. The main elements in competition policy rules will also be discussed. Thus, we will distinguish between legal and illegal behavior and thereby gain insight in business ethical issues.

    Some of the topics the course will cover are:

    • Market structure and network effects
    • Pricing and price discrimination
    • Static and dynamic games
    • Price and capacity setting in oligopoly
    • Competition vs collusion
    • Product differentiation
    • Asymmetric information

  • Learning outcome


    Upon completion of the course, students can:

    • Explain basic game theoretical concepts and apply it to strategic interaction between firms


    Upon completion of the course, students can:

    • Discuss strategic interactions between firms in a specific market
    • Analyze outcome in a market, for instance in prices and sales, and evaluate how the outcome might change if the basic assumption about the market structure changes
    • Find, evaluate and refer to information and scholarly subject matter and present it in a manner that sheds light on a problem seen from a firm's perspective

    General competence

    • Distinguish between relevant theoretical models for firm behavior and combine theory and factual data
