Are obligations of collective agents—such as states, businesses, and non-profits—ever overdemanding? I argue they are not. I consider two seemingly attractive routes to collective overdemandingness: that an obligation is overdemanding on a collective just if the performance would be overdemanding for members; and that an obligation is overdemanding on a collective just if the performance would frustrate the collective’s permissible deep preferences. I reject these. Instead, collective overdemandingness complaints should be reinterpreted as complaints about inability or third-party costs. These are not the same as overdemandingness. Accordingly, we can ask an awful lot of collective agents.

Individuals have various kinds of obligations: keep promises, don’t cause harm, return benefits received from injustices, be partial to loved ones, help the needy and so on. How does this work for group agents? There are two questions here. The first is whether groups can bear the same kinds of obligations as individuals. The second is whether groups’ pro tanto obligations plug into what they all-things-considered ought to do to the same degree that individuals’ pro tanto obligations plug into what they all-things-considered ought to do. We argue for parity on both counts.

If group members aim to fulfil a collective obligation, they must act in such a way that the composition of their individual actions amounts to a group action that fulfils the collective obligation. We study a strong sense of joint action in which the members of a group design and then publicly adopt a group plan that coordinates the individual actions of the group members. We characterize the conditions under which a group plan successfully coordinates the group members’ individual actions, and study how the public adoption of a plan changes the context in which individual agents make a decision about what to do.
