Dynamic games and forward induction
WebInteractive epistemology in dynamic games studies forms of strategic reasoning like backward induction and forward induction by formally representing the players' beliefs … Webof dynamic games, namely, backward induction, forward induction, and approxi-mation of in nite horizon by nite horizon. Because we drop the stagewise public randomization, new technical di culties arise in the proofs. The main purpose of the step of backward induction is to show that if the payo correspondence at

WebMay 1, 2012 · Forward induction is the notion that players in a game assume, even when confronted with an unexpected event, that their opponents chose rationally. It is often motivated by invariance, namely, that the normal form game captures all strategically relevant information. ... At the beginning of a dynamic game, players may have … WebThe latter is in contrast with forward induction—viz., common strong belief in rationality—that predicts {LA}×{CC}, as well as with backward induction—viz., common belief in future rationality—that yields {LA,LB,RA}×{CC,CD,DC, DD}. The reason for these deviations is that Ann can only use some—but not her
WebEvery finite game of perfect information has a pure strategy Nash equilibrium that can be derived through backward induction. Moreover, if no player has the same payoffs at any two terminal nodes, then backward induction results in a unique Nash equilibrium. Proof : MWG pp. 272-273. I Remark: Every finite game of perfect information has a PSNE.
