Harsanyi transformation

Target entity: Harsanyi transformation
Context triple: [John Harsanyi, knownFor, Harsanyi transformation]

• A. Kuhn’s theorem
  Kuhn’s theorem is a fundamental result in game theory that shows any finite extensive-form game with perfect recall has an equivalent normal-form (strategic-form) representation, ensuring the existence of mixed-strategy equilibria.
• B. “Extensive Games and the Problem of Information”
  “Extensive Games and the Problem of Information” is a foundational paper in game theory by Harold W. Kuhn that formalizes extensive-form games and introduces key concepts for analyzing strategic interaction under imperfect information.
• C. expected utility theory (with John von Neumann)
  Expected utility theory (with John von Neumann) is a foundational framework in economics and decision theory that models how rational agents make choices under uncertainty by maximizing the expected value of a utility function.
• D. Nash equilibrium
  A Nash equilibrium is a game-theoretic solution concept where no player can improve their payoff by unilaterally changing their strategy, given the strategies of all other players.
• E. Kalai–Smorodinsky bargaining solution
  The Kalai–Smorodinsky bargaining solution is a cooperative game theory concept that selects a fair agreement between parties by preserving proportional gains relative to their best possible outcomes.
• F. None of above. chosen
• G. Unsure - the case is ambiguous/there is not enough information to decide.

Target entity: Harsanyi transformation
Target entity description: The Harsanyi transformation is a game-theoretic method that converts games with incomplete information into games with imperfect information by introducing "types" and a common prior over them.
