Before revision:  We allow for a possibly fully connected network and a general class of estimands , which encompasses average treatment and average spillover effects, as well as estimands obtained from interactions of the  two.
After revision:  We allow for a possibly fully connected network , (ii) spillover effects occurring across neighbors, (iii) local dependence of unobservables characteristics. We allow for a class of estimands , which encompasses average treatment and average spillover effects, as well as estimands obtained from interactions of the two.
