The Theory of 2x2 Games
Ten Games: A Novel Categorization of All 2x2
Games". (This version: January 2012.)
Abstract: This paper provides a pedagogically useful categorization of all 2x2 games as one of ten types: (i) Slam Dunk, (ii) Immovable Object, (iii) Prisoners' Dilemma, (iv) Happy Marriage, (v) Food Fight, (vi) Master and Beloved Servant, (vii) Master and Annoying Servant, (viii) Assurance, (ix) Chicken, and (x) Hide and Seek. For each type of game, I characterize the commitment strategies (e.g. "moving first" or "making a promise") that allow each player to enjoy his/her best achievable payoff.
"Endogenous Timing of Moves in 2x2 Games". (This version: January 2012.)
Abstract: Suppose that, prior to playing a game, each player first commits whether to move "early" or "late". If both move early or both move late, the game then has simultaneous moves; otherwise, it has sequential moves. In all 2x2 games having a unique Nash equilibrium, the equilibrium outcome of this meta-game is unique and does not depend on the timing of players; commitments to move early or late.
