People often form expectations about others using the lens of their own attitudes (the so-called consensus effect). We study the implications of this for trust and trustworthiness. Trustworthy individuals are more \optimistic" than opportunists and are accordingly less afraid to engage in...

A central assumption of the canonical cheap talk literature is that people misreport their private information if this is to their material benefit. Recent evidence from laboratory experiments with student subjects suggests, however, that while many people do report the payoff-maximizing...

In this study, we use an allocation game to study the effects of group identity and group size on in-group favouritism when the person's own payoff is not affected by her decision. We first show that in a triadic setting when the subjects are asked to allocate a fixed amount of resource between...

A stream of research examining the effect of punishment on conformity indicates that punishment can backfire and lead to suboptimal social outcomes. In such studies, the enforcement of a behavioral rule to cooperate originates from a single party. This feature may raise concern about the...

When faced with the choice of behaving corruptly, are people more willing to accept a bribe or to embezzle money? Situations of bribery and embezzlement usually differ in their decision-making dynamics, with bribery requiring coordination between decision-makers (i.e., briber and bribee) while...

This paper studies responsibility attribution for outcomes of collusive bribery. In an experiment, participants labeled as either citizens or public officials can propose a bribery transaction to another participant (labeled as either public official or citizen, respectively), who decides...

After an unsatisfactory purchase, many firms are quick to apologize to customers. It is, however, not clear why they should do that. As the apology is costless, it should be regarded as cheap talk and thus ignored by the customer. In this paper, we test in a controlled field experiment whether...

This paper examines the incentives of a firm to invest in information about the quality of its product and to disclose its findings. If the firm holds back information, it might be detected and fined. We show that optimal monitoring is determined by a trade-off. Stricter enforcement reduces the...

Private information is at the heart of many economic activities. For decades, economists have assumed that individuals are willing to misreport private information if this maximizes their material payoff. We combine data from 72 experimental studies in economics, psychology and sociology, and...

This paper presents a simple adaptive model of demand adjustment in cooperative games, and analyzes this model in weighted majority games. In the model, a randomly chosen player sets his demand to the highest possible value subject to the demands of other coalitions members being satisfied. This...
