We can use Game Theory methods to analyse both these
situations. Wherever we have economic players
bargaining for the allocation of scarce resources in order
to attain their utility functions, to secure the outcomes and
consequences (the value, the preference, that the player
attaches to his outcomes) which are right for them - we
can use Game Theory (GT).
A short recap of the basic tenets of the theory might be in
order.
GT deals with interactions between agents, whether
conscious and intelligent - or Dennettic. A Dennettic
Agent (DA) is an agent that acts so as to influence the
future allocation of resources, but does not need to be
either conscious or deliberative to do so. A Game is the
set of acts committed by 1 to n rational DA and one a-
rational (not irrational but devoid of rationality) DA
(nature, a random mechanism). At least 1 DA in a Game
must control the result of the set of acts and the DAs must
be (at least potentially) at conflict, whole or partial. This
is not to say that all the DAs aspire to the same things.
They have different priorities and preferences. They rank
the likely outcomes of their acts differently. They engage
Strategies to obtain their highest ranked outcome. A
Strategy is a vector, which details the acts, with which the
DA will react in response to all the (possible) acts by the
other DAs. An agent is said to be rational if his Strategy
does guarantee the attainment of his most preferred goal.
Nature is involved by assigning probabilities to the
outcomes. An outcome, therefore, is an allocation of
resources resulting from the acts of the agents. An agent is
said to control the situation if its acts matter to others to
the extent that at least one of them is forced to alter at
least one vector (Strategy). The Consequence to the agent
is the value of a function that assigns real numbers to each
of the outcomes. The consequence represents a list of
outcomes, prioritized, ranked. It is also known as an
ordinal utility function. If the function includes relative
numerical importance measures (not only real numbers) -
we call it a Cardinal Utility Function.
Games, naturally, can consist of one player, two players
and more than two players (n-players). They can be zero
(or fixed) - sum (the sum of benefits is fixed and whatever
gains made by one of the players are lost by the others).
They can be nonzero-sum (the amount of benefits to all
players can increase or decrease). Games can be
cooperative (where some of the players or all of them
form coalitions) - or non-cooperative (competitive). For
some of the games, the solutions are called Nash
equilibria. They are sets of strategies constructed so that
an agent which adopts them (and, as a result, secures a
certain outcome) will have no incentive to switch over to
other strategies (given the strategies of all other players).
