Topologies on types
Dekel, Eddie; Fudenberg, Drew; Morris, Stephen - 2006
We de.ne and analyze a strategic topology on types in the Harsanyi-Mertens-Zamir universal type space, where two types are close if their strategic behavior is similar in all strategic situations. For a .xed game and action de.ne the distance be-tween a pair of types as the diþerence between...

Efficient use of information and social value of information
Angeletos, George-Marios; Pavan, Alessandro - 2006
This paper analyzes equlibrium and welfare for a tractable class of economies (games) with externalities, strategic complementarity or substitutability, and heterogenous information. First, we characterize the equilibrium use of information; complementarity heightens the sensitivity of...

Spin doctors: An experiment on vague disclosure
Deversi, Marvin; Ispano, Alessandro; Schwardmann, Peter - 2022
Unfavorable news are often delivered under the disguise of vagueness. Our theory-driven laboratory experiment investigates this strategic use of vagueness in voluntary disclosure and asks whether there is scope for policy to improve information transmission. We find that vagueness is profitably...

Communication, timing, and common learning
Steiner, Jakub; Stewart, Colin - 2010
We study the effect of stochastically delayed communication on common knowledge acquisition (common learning). If … messages do not report dispatch times, communication prevents common learning under general conditions even if common knowledge … is acquired without communication. If messages report dispatch times, communication can destroy common learning under …

Information independence and common knowledge
Gossner, Olivier; Kalai, Ehud; Weber, Robert - 2007
Conditions of information independence are important in information economics and game theory. We present notions of partial independence in Bayesian environments, and study their relationships to notions of common knowledge.

Information independence and common knowledge
Gossner, Olivier; Kalai, Ehud; Weber, Robert - 2009
In Bayesian environments with private information, as described by the types of Harsanyi, how can types of agents be (statistically) disassociated from each other and how are such disassociations reflected in the agents' knowledge structure? Conditions studied are (i) subjective independence...

Common knowledge of rationality and market clearing in economies with asymmetric information
Ben-Porath, Elchanan; Heifetz, Aviad - 2010
Consider an exchange economy with asymmetric information. What is the set of outcomes that are consistent with common knowledge of rationality and market clearing? To address this question we define an epistemic model for the economy that provides a complete description not only of the beliefs...
