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...

In this paper, we propose and analyse a game-theoretic model for multiplexity in signed networks through strategic interactions in a finite population of n players who are linked to each other in an underlying signed social network of friendships and enmities, g, through which players experience...

Hierarchy plays an integral role in organizational structure and practices, as well as in society more generally. In Confucian-influenced cultures, and especially in South Korea, social hierarchies are often based on age, and age dynamics can therefore influence social decision-making and...

Is feedback on trustworthiness necessary for the functioning of economic relationships? In many real-world economic environments, such feedback can at best be acquired through costly monitoring, raising questions of how trust and efficiency can be maintained. In the lab, we conduct a modified...

Standard game-theoretic analysis of a principal-agent problem postulates that in a one-period game the agent will not choose non-contractible quality. However, evidence exists that service providers choose costly quality in non-contractible dimensions, even in absence of reputation concern, if...

Game theory is explicitly a theory of how human minds operate. Game theory, however, fails comprehensively as a predictor of human behavior. The failure of game theory is attributable to its mistaken theory of mind. This theory of mind was derived from notions and models of cognitive...

We present an endogenous-timing conflict game of incomplete information under strategic complementarity. The model predicts multiple equilibria, in which the outcome follows either a simultaneous move game (Baliga and Sjostrom, 2004) or a sequential game, which improves social welfare. We study...

We present a non-technical assessment of the effects of the COVID-19 pandemic on individual level conflict behavior in the household, workplace, and societal interactions in the post-COVID era. We predict that there will be an increase in the intra-household conflict including domestic violence;...

A committee chooses whether to approve a proposal that some members may consider ethical. Members who vote for the proposal receive expressive utility, and all pay a cost if the proposal is accepted. Committee members have different depths of reasoning. The model predicts that features that...

For choice with deterministic consequences, the standard rationality hypothesis is ordinality, i.e., maximization of a weak preference ordering. For choice under risk (resp. uncertainty), preferences are assumed to be represented by the objectively (resp. subjectively) expected value of a von...
