The document discusses game theory and its applications to modeling conflict situations. It provides examples of classical game theory models - the coordination game, battle of the sexes game, chicken game, and prisoner's dilemma game. Each game represents a different type of strategic interaction between two players with competing preferences. The document also discusses a real-world example of bidding strategy, showing how a two-tiered bid can be advantageous by creating a prisoner's dilemma for other bidders.

What is game theory?
• Game theory is a branch of applied
mathematics that studies strategic situations
where participants choose different actions in
an attempt to maximize their returns.

Attention!
• Bad news:
Knowing game theory does not guarantee
winning
• Good news:
Framework for thinking about strategic
interaction

Why game theory?
• Because we can formulate effective strategy…
• Because we can predict the outcome of
strategic situations…
• Because we can select or design the best
game for us to be playing…

• Send a message one way communication
• Select your preference and guarantee at least
one point!
• Guess based on previous experience of OTHER
preferences

The Prisoners’ Dilemma game!
• If YOU and OTHER choose choice A, you both
win 3 points
• If YOU choose A and OTHER chooses B, you
win 1 point, and OTHER wins 4 points
• If YOU choose B and OTHER chooses A, you
win 4 points and OTHER wins 1 point
• If you both chose B, you both get 2 points

Same Example
• If YOU and OTHER develop using Windows, you
get paid 3 M$ each
• However, if only one of you develops for Linux, he
gets 4 M$ for being distinguished, while the other
only gets 1 M$ for being so old fashioned
• If you both develop for Linux, you get paid only 2
M$ each as there is no distinguishing and you
probably used open source code!

to develop using Linux! … It is safer!!!

Bidding Example!

Two-Tiered bidding
• In 1988 “Bloomingdales” had a market price of
100$ per share … it is being sold out!
• “Macy’s” offered 102$ per share provided that
they get majority of stocks (50% +1)
• Robert Campeau offered a two-tiered offer of
105-90$ per share for the first 50% of shares,
he pays 105$ per share for all shares and for the
rest he pays an extra 90$ per share for all shares!

Let’s use numbers
• If there are only 10 shares … the total share
price is 1000$
• If Macy’s took over, they will pay 102$ for
each of the first 5 shares and the rest remains
for 100$, the total price will be 1010$
• If Campeau gets the first 5 shares, he will pay
525$ for them, for the other 5 shares, he will;
pay 450$ for a total of 975$ !!!
