We analyze an economy with asymmetric information and endogenize the possibilities for information transmission between members of a coalition. We then define a concept of the Core that takes into account these communication possibilities. The internal consistency of the improvements is...

This paper analyzes the implications of currency crises in a model with unique equilibrium. Starting from a typical multiple equilibria model with self-fulfilling expectations we introduce noisy information, following Morris/Shin (1999). Under certain conditions for the noise parameter, all...

In this paper, we extend Aumann’s (Ann Stat 4:1236–1239, <CitationRef CitationID="CR1">1976</CitationRef>) probabilistic agreement theorem to situations in which agents’ prior beliefs are represented by a common neo-additive capacity. In particular, we characterize the family of updating rules for neo-additive capacities, which are...</citationref>

We study how asymmetric information affects market volatility in a linear setup where the outcome is determined by forecasts about this same outcome. The unique rational expectations equilibrium will be stable when it is the only rationalizable solution. It has been established in the literature...

We study how asymmetric information affects the set of rationalizable solutions in a linear setup where the outcome is determined by forecasts about this same outcome. The unique rational expectations equilibrium is also the unique rationalizable solution when the sensitivity of the outcome to...
