Off the equilibrium path
WebbThe intuitive criterion, like most refinement techniques, is based on restricting the beliefs off the equilibrium path. The intuitive criterion was presented by In-Koo Cho and David M. Kreps in a 1987 article. Their idea was to try to reduce the set of equilibria by requiring off-equilibrium receiver beliefs to be reasonable in some sense. WebbWe get off the equilibrium path when 1 deviates. Suppose 1 plays q 1 ≠ 64; f.i., he plays q 1 = 50. Then 2's best reply should be q 2 ∗ ( 50) = 425 whereas her plan is to play q 2 = 1000. So she is not best replying to 1's possible deviations. Share Cite Follow answered Jan 20, 2024 at 22:10 mlc 5,390 3 17 35 Add a comment

Webboff-the-equilibrium-path beliefs (i.e., many inferences that the second player could make after observing a message that, in equilibrium, would not be sent by the first player). One way to eliminate some of the beliefs is to ask the following questions: (i) Which out-of-equilibrium messages should not "reasonably" be expected
Consistency: each belief should be updated according to the equilibrium strategies, the observed actions, and Bayes' rule on every path reached in equilibrium with positive probability. On paths of zero probability, known as off-equilibrium paths, the beliefs must be specified but can be arbitrary. Visa mer In game theory, a Perfect Bayesian Equilibrium (PBE) is an equilibrium concept relevant for dynamic games with incomplete information (sequential Bayesian games). It is a refinement of Bayesian Nash equilibrium (BNE). … Visa mer • Sequential equilibrium - a refinement of PBE, that restricts the beliefs that can be assigned to off-equilibrium information sets to "reasonable" ones. • Intuitive criterion Visa mer Gift game 1 Consider the following game: • The sender has two possible types: either a "friend" (with probability $${\displaystyle p}$$) … Visa mer A multi-stage game is a sequence of simultaneous games played one after the other.

Repeated public-good game The following game is a simple representation of the Visa mer WebbIn this chapter we present and study some refinements of the concept of Nash equilibrium. In Section 7.1 we study subgame perfect equilibrium, which is a solution concept for extensive-form games. The idea behind this refinement is to rule out noncredible threats, that is, “irrational” behavior off the equilibrium path whose goal is …
