Note: Given that a second mover’s product
development costs can be much lower than the
first mover’s product development costs, firstmover advantages must be substantial to justify
first moving as a strategy.

Technological Leadership
In the 1970s, DuPont built a dominant position in
the titanium dioxide market by exploiting:
• superior technology
• scale economies
• accumulated experience for low costs
Gillette competes with a differentiation strategy in
disposable razors by exploiting:
• superior technology
• reputation
• broad distribution

Analyzing Competitive Dynamics Commitment Vs. Flexibility

Game Theoretic preemption strategy
Flexibility
Real (Strategic) Options Analysis
Factors Affecting The Likelihood of Competitor Response:
What are the payoffs relative to other
actions the competitor could take?
What prior strategic commitments has the
competitor made?
Does the potential market fit with the
competitor’s existing strategy?
How “reversible” is your action or the
competitor’s potential response?

Dominant Strategy (Nash) Equilibrium:

Note: It is a dilemma since if they both
cooperated by remaining silent: (-1, -1).
Game Theory and Strategy
The prisoners’ dilemma game can occur in
many contexts:
What is best
a division.
What is best
firm.
What is best
industry.
What is best
a nation.
What is best
world.
for an individual may not be best for

for a nation may not be best for the
Game Theory and Strategy
Now that we have learned the concept
of dominant strategy equilibrium, there
is a second important equilibrium
concept called a Nash equilibrium.
Note: All dominant strategy equilibrium
are Nash equilibrium, but not all Nash
equilibrium are dominant strategy
equilibrium.
Game Theory and Strategy
Game with no dominant strategy
equilibrium, but a Game with a Nash
equilibrium.

Game Theory and Strategy
Lessons
1. Commitment (sunk costs) can be used to
achieve cooperation.
The importance of mutual economic
hostages: The wise manager should think
beyond Machiavelli’s myopic approach to
contracting and should seek both to give and
receive credible (sunk cost) commitments that
facilitate ongoing relationships and adaptation.

2. Commitment (sunk costs) can be
used to achieve competitive
advantage.
• preemption strategy
Game Theory and Strategy
Some key points on strategic commitment:
Always give attention to how your competitors’
returns vary under different strategic scenarios;
It is important to communicate the commitment
to the other firms (for both competition and
cooperation);
“Sunk cost” investments can be used to precommit to a certain strategy and, thus, influence
competitor response; and
Understand what strategic investments are
important in your business and how “sunk” those
investments are.
