Drawing from conflicts observed in online communities (e.g., astroturfing and shadow banning), I extend Pietraszewski’s theory to accommodate phenomena dependent on the intersubjectivity of groups, where representations of group membership (or beliefs about group membership) diverge. Doing so...

Using a repeated public goods game, we experimentally examine how apologies support mutual cooperation in groups. In two treatments where participants can send either public apologies or private apologies, contributions increase by 0.37 and 0.61 standard deviations respectively, compared to a...

This paper studies career concerns in groups where workers can allocate effort between their own tasks and other group members' tasks. We first theoretically investigate how workers allocate effort when they have career concerns. Then, we study their decisions when the labor market can only...

Betrayal aversion is an important factor in the decision to trust.Trust in members of one's own social group (ingroup members) is often higher than that in members of other groups (outgroup members). In this paper, I study (i) how betrayal aversion contributes to in-/outgroup discrimination in...

In this paper, we study collective information acquisition in groups that make decisions using majority rule. We argue both theoretically and experimentally that the median voter theorem does not apply; in general, the level of information acquired by the group is not equal to the level of...

We develop a framework of group corruption via back-door negotiations between an outside initiator and an authority of decision-makers in a hierarchical organization. We examine the role played by the architecture of a multi-tier authority and determine under such a structure how bargaining...

Group decision-making in organizations often occurs in the context of influence relationships. We develop a theory anchored in a computational model to analyze the conditions under which social influence structures aid or hurt information aggregation. We find that a group is most likely to...

Purpose - In the presence of coronavirus disease 2019 (COVID-19), due to the social distance restriction, consumers' regular consumption behaviors and patterns have been changing fundamentally. Thereafter, an innovative group buying model has emerged and developed explosively with a specific...
