Asheim, Geir B.; Voorneveld, Mark; Weibull, Jörgen W. - In: Games 7 (2016) 4, pp. 1-16

We define a concept of epistemic robustness in the context of an epistemic model of a finite normal-form game where a player type corresponds to a belief over the profiles of opponent strategies and types. A Cartesian product X of pure-strategy subsets is epistemically robust if there is a...

Epistemically robust strategy subsets

Asheim, Geir B.; Voorneveld, Mark; Weibull, Jörgen W. - 2016

We define a concept of epistemic robustness in the context of an epistemic model of a finite normal game where a player type corresponds to a belief over the profiles of opponent strategies and types. A Cartesian product X of pure strategy subsets is epistemically robust if there is a Cartesian...

Rational Belief Bubbles

Sohn, H. - 2018

We propose an extension of the class of rational expectations bubbles (REBs) to the more general rational beliefs setting of Kurz (1994a,b). In a potentially non-stationary but stationarizable environment, it is possible to hold more than one (small-r) “rational” expectation. When rational...

Circles of Trust : Rival Information in Social Networks

Persson, Petra; Roketskiy, Nikita; Lee, Samuel - 2021

We analyze the diffusion of rival information in a social network. In our model, rational agents can share information sequentially, unconstrained by an exogenous protocol or timing. We show how to compute the set of eventually informed agents for any network, and show that it is essentially...

Weakly rational expectations

Hellman, Ziv - In: Journal of Mathematical Economics 49 (2013) 6, pp. 496-500

systems, in which there is common knowledge of rationality and a common prior. We show here that common knowledge of … rationality is not needed: when rationality is satisfied in the support of an action-consistent distribution (a concept introduced … rational belief systems’ there may not be mutual knowledge of rationality, let alone common knowledge of rationality. In the …

Endogenous Selection of Aspiring and Rational Rules in Coordination Games

Dziubiński, Marcin; Roy, Jaideep - 2010

The paper studies an evolutionary model where players from a given population are randomly matched in pairs each period to play a coordination game. At each instant, a player can choose to adopt one of the two possible behavior rules, called the rational rule and the aspiring rule, and then take...

Belief-Free Rationalizability and Informational Robustness

Bergemann, Dirk; Morris, Stephen - 2016

We propose an incomplete information analogue of rationalizability. An action is said to be belief-free rationalizable if it survives the following iterated deletion process. At each stage, we delete actions for a type of a player that are not a best response to some conjecture that puts weight...
