Using Aggregated Relational Data to Feasibly Identify Network Structure without Network Data

Am Econ Rev. 2020 Aug;110(8):2454-2484. doi: 10.1257/aer.20170861.

Abstract

Social network data are often prohibitively expensive to collect, limiting empirical network research. We propose an inexpensive and feasible strategy for network elicitation using Aggregated Relational Data (ARD): responses to questions of the form "how many of your links have trait k ?" Our method uses ARD to recover parameters of a network formation model, which permits sampling from a distribution over node- or graph-level statistics. We replicate the results of two field experiments that used network data and draw similar conclusions with ARD alone.
