Query: Using Aggregated Relational Data to feasibly identify network structure
  without network data   Social network data is often prohibitively expensive to collect, limiting
empirical network research. Typical economic network mapping requires (1)
enumerating a census, (2) eliciting the names of all network links for each
individual, (3) matching the list of social connections to the census, and (4)
repeating (1)-(3) across many networks. In settings requiring field surveys,
steps (2)-(3) can be very expensive. In other network populations such as
financial intermediaries or high-risk groups, proprietary data and privacy
concerns may render (2)-(3) impossible. Both restrict the accessibility of
high-quality networks research to investigators with considerable resources.
  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 social connections have trait k?" Our method uses ARD to recover
the parameters of a general network formation model, which in turn, permits the
estimation of any arbitrary node- or graph-level statistic. The method works
well in simulations and in matching a range of network characteristics in
real-world graphs from 75 Indian villages. Moreover, we replicate the results
of two field experiments that involved collecting network data. We show that
the researchers would have drawn similar conclusions using ARD alone. Finally,
using calculations from J-PAL fieldwork, we show that in rural India, for
example, ARD surveys are 80% cheaper than full network surveys.
