Neeman (2004) and Heifetz and Neeman (2006) have shown that, in auctions with incomplete information about payoffs, full surplus extraction is only possible if agents’ beliefs about other agents are fully informative about their own payoff parameters. They argue that the set of...

The paper explains how workers' expectations of being discriminated against can be self-confirming, accounting for the persistence of unequal outcomes in the labour market even beyond the causes that originally generated them. The theoretical framework used is a two-stage game of incomplete...

We consider the following belief free solution concepts for games with incomplete information: (i) incomplete information rationalizability, (ii) incomplete information correlated equilibrium and (iii) ex post equilibrium. We present epistemic foundations for these solution concepts and...

In a market with stochastic demand at most one seller can acquire costly information about demand. Other sellers entertain idiosyncratic beliefs about the market demand and whether there exists an informed seller. These idiosyncratic beliefs co-evolve with the potential insider's inclination to...

We build a model of network dynamics with decision-making under incomplete information in order to understand the determinants of the observed gradual downgrading of expert opinion on complicated issues and the decreasing trust in science. We suggest a search and matching mechanism behind...

We characterize the impact of anticipatory utility on players' subjective interpretation of information in a general coordination game. In any symmetric equilibrium, players choose to over-estimate the precision of their information. Players' perception of public information quality relative to...

Social media have become an increasingly important source of information about political, social and economic issues. While beneficial on many levels, the decentralized nature of these media may expose societies to novel risks of manipulation by third parties. To evaluate these risks, we study a...

We relax the common assumption of homogeneous beliefs in principal-agent relationships with adverse selection. Principals are competitors in the product market and write contracts also on the base of an expected aggregate. The model is a version of a cobweb model. In an evolutionary learning...

Why do people appear to forgo information by sorting into “echo chambers”? We construct a highly tractable multi-sender, multi-receiver cheap talk game in which players choose with whom to communicate. We show that segregation into small, homogeneous groups can improve everybody’s...
