  This paper builds on an existing notion of group responsibility and proposes
two ways to define the degree of group responsibility: structural and
functional degrees of responsibility. These notions measure the potential
responsibilities of (agent) groups for avoiding a state of affairs. According
to these notions, a degree of responsibility for a state of affairs can be
assigned to a group of agents if, and to the extent that, the group has the
potential to preclude the state of affairs.
