Query: Homophily in preferences or meetings? Identifying and estimating an
  iterative network formation model   Is homophily in social and economic networks driven by a taste for
homogeneity (preferences) or by a higher probability of meeting individuals
with similar attributes (opportunity)? This paper studies identification and
estimation of an iterative network game that distinguishes between these two
mechanisms. Our approach enables us to assess the counterfactual effects across
time of changing the meeting protocol between agents. As an application, we
study the role of preferences and meetings in shaping classroom friendship
networks in Brazil. We find that in a network structure in which homophily due
to preferences is stronger than homophily due to meeting opportunities,
tracking students may lead to welfare improvement, but the relative benefit of
this policy diminishes over the school year.
