Game Theory and Coopetition
Learning Objectives
Understand cooperative game theory concepts.
Familiarization with the PARTS framework:
Players
Added Value
Rules
Tactics
Scope
Use the PARTS framework to describe and analyze business games and their evolution over time.
Define the concept of complementors and evaluate competition among them.
Differentiate between "hard" and "soft" power strategies to influence complementors.
Understand principles of co-opetition-based business models and analyze Amazon's co-opetition model.
Introduction to Cooperative Game Theory
In strategic networks and ecosystems, businesses must determine whom to cooperate or compete with in dynamic coalitions, often simultaneously (coopetition).
Definition of Coopetition: A business strategy combining cooperation and competition.
Derived from work by Professors Adam M. Brandenburger and Barry J. Nalebuff (published in Co-opetition, 1996).
Example: Pfizer and BioNTech collaborated on the COVID-19 vaccine, where they combined resources to develop and manufacture the vaccine rapidly.
PARTS Framework
Players: Entities engaged in transactions or interactions within networks.
Added Value: The benefit or worth derived from a player's involvement in transactions (AVi = v(N) - v(N\i)).
Rules: Frameworks established by laws, traditions, or contracts that govern player interactions.
Tactics: Strategies utilized to influence perceptions and decision-making processes within the network.
Scope: The boundaries and operational space of the game or network, where shifts in scope can impact player interactions and strategies significantly.
Analysis of Cooperative Games
Coalitions: Potential alliances among players to maximize advantages.
Value Creation Example:
In a game where:
Seller A has costs of CHF 4.
Buyer B1 values the product at CHF 7.
Buyer B2 values the product at CHF 9.
Value creation achieved through transactions can be defined as the difference between buyer willingness= to pay and seller costs.
Possible Coalitions and Value Created:
{A}: v(S) = 0
{B1}: v(S) = 0
{B2}: v(S) = 0
{A, B1}: v(S) = 3
{A, B2}: v(S) = 5
Cooperative vs Non-cooperative Game Theory
Cooperative Game Theory: Focuses on forming alliances and coalitions; examines the potential for cooperation as a side effect of the game.
Non-cooperative Game Theory: Pertains to strategic interactions without collusion among players where cooperation is not formalized.
Most business scenarios are represented as non-zero-sum games, where multiple players can derive benefit, thus allowing for win-win strategies.
Strategic Value Creation
Game theory provides tools to analyze:
Interplay between cooperation and competition.
Assess positioning within the network.
Anticipate competitors’ reactions and discover strategies to gain advantages.
Illustrates how best strategies can be determined and what boundaries to cooperation exist.
Key Strategies in Coopetition-Based Business Models
Goals of Coopetition-Based Business Modelling:
Increase market size
Develop new markets
Efficient resource utilization
Improve competitive position
Example of Successful Coopetition:
Sony and Samsung in LCD TV development.
BMW and Toyota’s collaboration on electric vehicles.
Complementors
Definition: Complementors are entities whose involvement increases a player’s value (distinguished from competitors, who diminish it).
Players can exert influence over complementors through:
Hard Power: Coercive influences based on market control or authority.
Soft Power: Persuasion and aligning interests without coercion.
Recognizing and managing relationships with complementors can provide significant strategic advantages.
Challenges and Considerations in Game Strategies
Avoid Thinking Traps:
Acceptance of the game as unchangeable.
Viewing success solely through a competitive lens.
Failing to consider the full landscape of player interactions.
Investigative Questions for Business Models:
Understand the motivations and strategies of complementors.
Assess potential conflicts and collaborative strategies.
Conclusion
A comprehensive understanding of cooperative game theory and the PARTS framework facilitates the effective navigation of strategic networks and business ecosystems, allowing for enhanced value creation and competitive positioning.
