We study markets for information in the form of Bayesian signals. The main feature of such markets is that information is costly for the seller to acquire and cannot be verified by the buyer. We provide a full characterization of the set of all compensation schemes (viz., menus) which guarantee...

In this paper we study common belief of rationality in strategic-form games with ordinal utilities, employing a qualitative doxastic model of beliefs. We characterize the three main solution concepts for such games, viz., Iterated Deletion of Strictly Dominated Strategies (IDSDS), Iterated...

Games in which players aim to guess a fraction or multiple p of the average guess are known as guessing games or (p-)beauty contests. In this note, we derive a full characterization of the set of rationalizable strategies and the set of pure strategy Nash equilibria for such games as a function...

Does the mere exposure of a subject to a belief elicitation task affect the very same beliefs that we are trying to elicit? Is it theoretically possible to guarantee that this will not be the case? In this paper, we introduce mechanisms that make it simultaneously strictly dominant for the...

Agents that are subject to persuasion attempts often employ strategies that allow them to effectively resist. In the context of Bayesian Persuasion (Kamenica and Gentzkow, 2011), we argue that if appropriate action-contingent payoff adjustments are available to the subject of persuasion (e.g.,...
