functional form of utility, we simply assume that the society is homogeneous, i.e. that agents' utilities differ only with … respect to their network position while their names do not matter. Existence of certain stable network structures is then … subgroup exist. If the society becomes more homogeneous, then it is possible to characterize the set of all pairwise stable …
