We consider a situation where groups negotiate over the allocation of a surplus (which is used to fund group specific goods). Each group is composed of agents who have differing valuations for public goods. Members choose a representative to take decisions on their behalf. Specifically,...

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...
