game theory - 2025 ACF Fall

Question

In this field, dealers are considered nature players because they have no strategic interests in the outcome. For 10 points each:

[10e] What field studies the Nash equilibria of situations like the Prisoner’s Dilemma and rock, paper, scissors?

ANSWER: game theory

[10m] Adding moves by the nature player transforms games with this resource from incomplete to imperfect. A George Akerlof paper that calls bad cars “lemons” discusses this resource’s “asymmetry.”

ANSWER: information [accept incomplete information; accept imperfect information; accept information asymmetry]

[10h] The extensive-form of a game allows a game with incomplete information to be represented as one of these objects via the Harsanyi transformation. Chess engines search “partial” examples of these objects.

ANSWER: game trees [accept decision trees; accept partial game trees]
