Users of the social networking service Facebook have the possibility to post status updates for their friends to read. In turn, friends may react to these short messages by writing comments or by pressing a Like button to show their appreciation. Making use of five Swedish accounts, we set up a...

We study a model of observational learning in a set of agents who are connected through a social network. The agents face identical decision problems under uncertainty, where they are not aware of the relative profitability of their alternative choices. They choose repeatedly from a common set...

This paper presents a novel mechanism under which diversity affects performance even if it has no direct impact on payoffs. Diversity matters because it influences the degree of strategic uncertainty that players face. We model this by incorporating the dual process account of Theory of Mind...

The compromise effect arises when options near the "middle" of a choice set are more appealing. The compromise effect poses conceptual and practical problems for economic research: by influencing choices, it distorts revealed preferences, biasing researchers' inferences about deep (i.e., domain...

We analyze the offering, asking, and granting of help or other benefits as a three-stage game with bilateral private information between a person in need of help and a potential help-giver. Asking entails the risk of rejection, which can be painful: since unawareness of the need can no longer be...

I experimentally investigate how vague language changes the nature of communication in a biased strategic information transmission game. Counterintuitively, when both precise and imprecise messages can be sent, in aggregate senders are more accurate and receivers trust them more. I also develop...

We report an experiment that infers true overconfidence in relative ability through actions, as opposed to reported beliefs. Subjects choose how to invest earnings from a skill task when the returns depend solely upon risk, or both risk and relative placement, enabling joint estimation of...

In this paper we build a theoretical model to show the role of self-confidence in leading to inefficient job matching equilibria: under-confident highly-qualified workers do not apply for highly-skilled jobs, because mistakenly perceive themselves as having relatively lower abilities with...

We perform a (psychological) game-theoretic analysis of cheating in the setting proposed by Fischbacher & Föllmi-Heusi (2013). The key assumption, which we refer to as perceived cheating aversion, is that the decision maker derives disutility in proportion to the amount in which he is perceived...

Redress to consumers following the mis-selling of financial products is an important regulatory tool to secure an appropriate degree of protection for consumers, one of the three operational objectives of the Financial Conduct Authority (FCA). In 2011/12, excluding compensation for payment...
