Nash equilibrium and backward induction
WitrynaA generalized backward induction (GBI) procedure is defined for all such games over the roots of subgames. A strategy profile that survives backward pruning is called a backward induction solution (BIS). ... Replace any ’proper subgame’ of the tree with one of its Nash-equilibrium payoffs, and perform backward induction on the … WitrynaThe Nash equilibrium (UA, X) is subgame perfect because it incorporates the subgame Nash equilibrium (A, X) as part of its strategy. To solve this game, first find the Nash Equilibria by mutual best response of Subgame 1. Then use backwards induction and plug in (A,X) → (3,4) so that (3,4) become the payoffs for Subgame 2.

Consider a dynamic game in which the players are an incumbent firm in an industry and a potential entrant to that industry. As it stands, the incumbent has a monopoly over the industry and does not want to lose some of its market share to the entrant. If the entrant chooses not to enter, the payoff to the incumbent is high (it maintains its monopoly) and the entrant neither loses nor gains (its payoff is zero). If the entrant enters, the incumbent can "fight" or "accommodate" the entrant. It … Witryna9 kwi 2024 · By specifying the selected Nash equilibrium strategy vectors as the players ’ behaviour strategies at every decision node / information set of the game , the …

Witrynaon Nash equilibrium as the solution concept. We turn next to dynamic games with complete information, for which we use backward induction as the solution con-cept. We discuss dynamic games with complete information that have multiple Nash equilibria, and we show how backward induction selects a Nash equilibrium that … WitrynaAs Figure 11.2 demonstrates, the second round is a one-round bargaining game, which implies that if it is reached then player 2 gets the whole pie in any subgame-perfect equilibrium. Continuing with backward induction, and assuming that δ ≤ 1, we can find the subgame-perfect equilibrium for the two-round game as follows. In the first round …
Witrynathen, even sharper refinements of Nash's equilibrium concept have appeared (Selten (1975), Kreps and Wilson (1982), Kohlberg and Mertens (1986)). A common thread among these has been the incorporation of some form of backward induction. (We use this term broadly. In particular, it includes Kreps and Wilson's (1982) notion of …
WitrynaA generalization of backward induction is subgame perfection. Backward induction assumes that all future play will be rational. In subgame perfect equilibria, play in every subgame is rational (specifically a Nash equilibrium).
