Can you beat the prisoner’s dilemma?
6 Competitor Analysis
Prisoners’ Dilemma Prisoner’s Dilemma is a situation where
individuals’ incentives and those of the group are in conflict: The group would jointly benefit from
cooperating, but… Each group member has an incentive not to
cooperate.
Cooperation tends to break down unless there is some mechanism to enforce cooperation.
We see this in many settings and knowing how to strategize in this context is critical. Politics: Arms races, pollution Sports: Steroid use Business: Price or advertising wars On campus: Group projects? Other?
7 Competitor Analysis
Formal Definition Prisoner’s Dilemma: Simultaneous-move
non-cooperative game where all players have a dominant strategy, and the resulting Nash equilibrium is Pareto inefficient.
Non-Cooperative Game: Each player seeks to maximize his/her individual payoff and assumes others do the same.
Dominant Strategy: A strategy that is always the best choice for a player, regardless of what other players choose to do.
Nash equilibrium: A combination of strategies where no player would wish to unilaterally change his/her strategy.
Pareto inefficient: The game has another possible outcome that would make at least one player better off, without making other players any worse off.

12 Competitor Analysis
Exercise: Knee-Jerk Reactions
How can we promote cooperation to preserve industry profitability?
Imagine a game between Genzyme and J&J to limit the “R&D war” (for the time being, ignoring other competitors)
Can they get control of R&D expenditures so they can realize a higher return?
20 Competitor Analysis
Repeated Prisoner’s Dilemma Games
Repeated games can lead to cooperation – even if they play “non-cooperatively.” Why? How?
What determines whether cooperation will emerge? Gains to defecting in the current round? Likelihood of retaliation in future rounds? Cost imposed by retaliation in future rounds? Relative value placed on future vs. present
payoffs?
Axelrod tested algorithms (2-player repeated games) Tit-for-tat worked best – cooperative in the 1st
round then repeat opponent’s prior move. Never instigate, always respond in kind, and always forgive.

Competitor’s Cognition
Beliefs: How does the competitor view the industry (themselves and rivals)?
Intentions: What are the competitor’s goals & objectives?
Past Actions: To what extent is the rival bound or constrained by past actions?

Key Points in Competitor Analysis
Estimate payoff structure. Assess payoffs to predict rival responses to proposed strategies.
Anticipate rivals’ perceptions. Market commonality, resource similarity & cognition indicate whether a move will elicit a response.
Collusion & prisoners’ dilemma. Sustaining cooperation requires an effective enforcement mechanism. Threat of retaliation depends on: Number of players Severity of retaliation Benefits of defecting Visibility of
defections Current v. future payoffs

49 Competitor Analysis
What Happened? Manchester United accepted a
£623.4m bid from BSkyB (9/98). UK Monopolies and Mergers
Commission blocked the bid (4/99). “The toehold effect would have consequences
for any future collective sale of Premier League rights …If BSkyB acquired Manchester United, 5-8% of whatever it paid to obtain the Premier League rights would flow back to it.”
BSB acquired 9.9% stakes in 4 Premier League clubs (Manchester United, Leeds United, Sunderland, Manchester City).
