Two approches to strategic interactionGame theory:

a theory of human behaviour in strategic settings

firms as rational agents that maximize their objectivefunction in interdependence conditions

Competitor profiling:

Observation of competitors’ actual behavior – what are their objectives, beliefs and organizational practices?

Anticipate and preempt competition

‘when you know yourself but do not know your enemy, you have equal possibilities to win or to loose ’

Sun Tsu, The Art of War

Game theory: basic notions

A strategic game is the context where interaction among agents takes place

A strategic game draws on a set of rules which participants are assumed to comply with.

In a strategic game the utility or payoff of each participant depends on its action and the action of other participants

Core notions: rationality Each player evaluates all possible consequences of her own actions

Assigns a consistent set of preferences over the consequences of actions

And chooses the actions which maximize her objective function

Static games One period

Participants make their choices simultaneously (strategicinteraction once for all)

No player can observe and react to the actual choices made by other players before making her own move

Players’ payoffs depend exclusively on the combination of strategies chosen in the same period.

Static games of complete information: each player’s payoff function is common knowledge
