We study nonparametric and regression estimators of treatment and spillover effects when
interference is mediated by a network. Inference is nonstandard due to dependence induced …

In response to a change, individuals may choose to follow the responses of their friends or,
alternatively, to change their friends. To model these decisions, consider a game where …

Many economic activities are embedded in networks: sets of agents and the (often) rivalrous
relationships connecting them to one another. Input sourcing by firms, interbank lending …

This paper is concerned with cross-sectional dependence arising because observations are
interconnected through an observed network. Following (Doukhan and Louhichi, 1999), we …

How to allocate vaccines over heterogeneous individuals is one of the important policy
decisions in pandemic times. This paper develops a procedure to estimate an individualized …

Homophily based on observables is widespread in networks. Therefore, homophily based
on unobservables (fixed effects) is also likely to be an important determinant of the …

This paper studies the dependence structure of sparse networks realized according to a
strategic model of network formation with homophilous agents. We argue that equilibrium …

We develop a two-stage game in which competing airlines first choose the networks of
markets to serve in the first stage before competing in price in the second stage. Spillovers in …

I study the problem of optimally distributing treatments among individuals on a network in the
presence of spillovers in the effect of treatment across linked individuals. I consider the …

The article analyzes nonnegative multivariate time series which we interpret as weighted
networks. We introduce a model where each coordinate of the time series represents a …
