When a player tries to choose the "best" strategy among a multitude of options, that player may compare two strategies A and B to see which one is better. The result of the comparison is one of: • B is equivalent to A: choosing B always gives the same outcome as choosing A, no matter what the other players do. • B strictly dominates A: choosing B always gives a better outcome than choosing A, no matter what the other players do. http://gametheory101.com/courses/game-theory-101/ex-ante-and-interim-dominance/

Equilibrium selection: Payoff or risk dominance?:

SpletFor a given initial game, the players engage in an endogenously determined number of commitment periods before choosing from the remaining actions. We show the existence of equilibria with pure strategies in the commitment periods. Partial characterization results for general games capture the tradeoff between commitment and deterrence. Splet04. jan. 2024 · Payoff = The value associated with a possible outcome of a game. Strategy = A rule or plan of action for playing a game. An optimal strategy is one that provides the best payoff for a player in a game. Optimal Strategy = A strategy that maximizes a player’s expected payoff.

"Splet04. maj 2024 · The payoff matrix is given in Table 2.1.1. In order to better see that this game is zero-sum (or constant-sum), we could give values for the amount of cake each player gets. For example, half the cake would be 50 %, a small piece might be 40 %. Then we can rewrite the matrix with the percentage values in Table 2.1.2. " - Payoff dominance

Payoff dominance

SpletIn a benchmark case, with only two firms and quadratic payoff functions, forces (i)-(iv) lead to weak increasing dominance. More generally, we identify additional effects that may work for or against increasing dominance, so that increasing dominance may be overturned if firms are sufficiently forward looking.
