Econometrics of network models

Abstract: In this article I provide a (selective) review of the recent econometric literature on networks. I start with a discussion of developments in the econometrics of group interactions. I subsequently provide a description of statistical and econometric models for network formation and approaches for the joint determination of networks and interactions mediated through those networks. Finally, I give a very brief discussion of measurement issues in both outcomes and networks. My focus is on identification and comp… Show more

“…This review complements other available overviews within econometrics by Graham (2015), Chandrasekhar (2015), de Paula (2017) and Graham (forthcoming). In particular, it follows closely (but expands upon) previous surveys in de Paula (2017) and corresponding material in Graham and de Paula (2020).…”

“…Secondly, it would be interesting to extend our approach to situations where players endogenously form pairs or groups in an unobserved manner to the researcher. Our approach might be extended to such situations, in combination with recent developments on network formation models (see de Paula, 2017). Thirdly, it may be beneficial to develop treatment evaluation techniques under treatment decision games of incomplete information.…”

“…As discussed by de Paula et al (2017b), the identification condition is closely linked to the sparsity of the network. We say that a network is sparse if it is not dense, where dense means that the number of links is O(m).…”

“…The assumption thatχ ij,ik (θ ) = 0 whenever max{d(i, j ), d(i, k)} >d implies that the individuals cannot receive positive payoffs from an infinite number of links, and it ensures that h ij (W m,−ij , θ) < ∞. 8 Note that this is weaker than assuming that individuals only have a finite number of links, as for instance in de Paula et al (2017a). Indeed, at this point, individuals can have an infinite number of links; however, only a finite number of those links can affect the payoff of any particular link.…”
