Query: Models, Methods and Network Topology: Experimental Design for the Study
  of Interference   How should a network experiment be designed to achieve high statistical
power? Ex- perimental treatments on networks may spread. Randomizing assignment
of treatment to nodes enhances learning about the counterfactual causal effects
of a social network experiment and also requires new methodology (ex. Aronow
and Samii 2017a; Bow- ers et al. 2013; Toulis and Kao 2013). In this paper we
show that the way in which a treatment propagates across a social network
affects the statistical power of an ex- perimental design. As such, prior
information regarding treatment propagation should be incorporated into the
experimental design. Our findings justify reconsideration of standard practice
in circumstances where units are presumed to be independent even in simple
experiments: information about treatment effects is not maximized when we
assign half the units to treatment and half to control. We also present an
exam- ple in which statistical power depends on the extent to which the network
degree of nodes is correlated with treatment assignment probability. We
recommend that re- searchers think carefully about the underlying treatment
propagation model motivat- ing their study in designing an experiment on a
network.
