We aim to understand the role and evolution of beliefs in the indefinitely repeated prisoner's dilemma (IRPD). To do so, we elicit beliefs about the supergame strategies chosen by others. We find that heterogeneity in beliefs and changes in beliefs with experience are central to understanding...

People often conform to others either pro-socially or self-interestedly. By conducting modified dictator game experiments where subjects observe others’ behaviors, this study analyzes how observational learning influences subjects’ conforming/non-conforming and pro-social/self-interested...

Substantial evidence has accumulated in recent empirical works on the limited ability of the Nash equilibrium to rationalize observed behavior in many classes of games played by experimental subjects. This realization has led to several attempts aimed at finding tractable equilibrium concepts...

One disputed topic in Organization and Management economics is how leadership and collusive agreements are set and maintained in industries where firms are characterised by similar technological opportunities and structures. This topic is particularly important to analyse online and digital...

To identify dual process reasoning in giving, we exposed experimental participants making a charitable donation to vivid images of the charity's beneficiaries in order to stimulate affect. We hypothesized that the effect of an affective manipulation on giving is larger when we simultaneously put...

Observational learning theories often assume that people's actions can be observed. However, in many naturally-occurring environments, individuals can choose whether to disclose their behavior to others. We provide theoretical analysis of observational learning under optional disclosure...

Shaun Nichols’ "Rational Rules" is the most creative and interesting response to moral nativism to appear since the naturalistic turn in moral psychology that began several decades ago. Nichols accepts the basic nativist observation that the moral rules children acquire are surprisingly rich...

A common feature of the literature on the evolution of preferences is that evolution favors nonmaterialistic preferences only if preference types are observable at least to some degree. We argue that this result is due to the assumption that in each state of the evolutionary dynamics some...
