The graph concordance measure can be generally used to quantify the empirical relevance of a network in explaining cross-sectional dependence of the outcomes, and as shown in the paper, can also be used to quantify the extent of homophily under certain conditions. When one observes a single large network, it is nontrivial to make inference about the concordance pattern.
