Altruism and other non-egoistic behaviour

Question 1

Present-aim standard

Answer 1

A person is deemed rational if they are efficient in the pursuit of whatever aims they hold at that moment of action

Question 2

Self-interest standard

Answer 2

A person is deemed rational if their motives are congruent with their narrow material interests (model non-egoistic preferences with standard-rational choice)

Question 3

Hawk and Dove model

Answer 3

Developed by John Maynard Smith: populations have aggressive Hawks and friendly Doves which creates a payoff matrix where Hawk>dove but 2 doves>2 Hawks. At equilibrium the payoff for hawks = payoff for doves

Question 4

Is there a dominate strategy in the Hawk-Dove model

Answer 4

NO! And the equilibrium is one of the two sub-optimal outcomes
