Consider a society where ethnic conflict is imminent due to people's belief about the state of the world. An `informed agent' is a player who has private information about the state. We analyze whether the informed agent can achieve peace by sending private messages to the players. If the...

We study experimentally the effectiveness of communication in common value committees exhibiting publicly known heterogeneous biases. We test models assuming respectively self-interested and strategic-, joint payoff-maximizing- and cognitively heterogeneous agents. These predict varying degrees...

In the past, many refinements have been proposed to select equilibria in cheap talk games. Usually, these refinements were motivated by a discussion of how rational agents would reason in some particular cheap talk games. In this paper, we propose a new refinement and stability measure that is...

Currently no refinement exists that successfully selects equilibria across a wider range of Cheap Talk games. We propose a generalization of refinements based on credible deviations, such as neologism proofness and announcement proofness. According to our Average Credible Deviation Criterion...

We theoretically and experimentally analyze the role of verifiability and privacy in strategic performance feedback using a “one principal-two agent” context with real effort. We confirm the theoretical prediction that information transmission occurs only in verifiable feedbackmechanisms and...

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...

We study experimentally persuasion games in which a sender (e.g., a seller) with private information provides verifiable but potentially vague information (e.g., about the quality of a product) to a receiver (e.g., a buyer). Various theoretical solution concepts such as sequential equilibrium or...

Unfavorable news are often delivered under the disguise of vagueness. But are people sufficiently naive to be fooled by such positive spin? We use a theoretical model and a laboratory experiment to study the strategic use of vagueness in a voluntary disclosure game. Consider a sender who aims at...

FeedbackWe theoretically and experimentally analyze public and private feedback in teams that are characterized by different performance technologies. We consider a setting where the principal can provide truthful information on agents’ performances or strategically withhold feedback. We find...

We design experimental games to evaluate the predictive power of the first cheap‐talk refinement, neologism‐proofness. In our first set of treatments designed to evaluate the refinement with its usual emphasis on literal meanings, we find that a fully revealing equilibrium that is...
