Many economic activities are embedded in networks: sets of agents and the (often) rivalrous relationships connecting …, among many, of networked economic activities. Motivated by the premise that networks' structures are consequential, this …, summary network parameters (e.g., the degree distribution or transitivity index); and (iii) empirical models of strategic …

This paper presents and structurally estimates a model of endogenous network formation and legislative activity of … of Congress as exogenously given and instead embed it in a model of endogenous network formation useful for developing …

We develop a theoretical model of security investments in a network of interconnected agents. Network connections … networks, is that because security investments create positive externalities on other agents, there will be underinvestment in … strategic substitutes. In a general (non-symmetric) network, this implies that underinvestment by some agents will encourage …

In this note, we consider a broad class of network models where a large number of heterogeneous agents simultaneously … wide variety of heterogeneous agent economies - characterized by spatial, production, or social networks - yield …

We develop and analyze a tractable empirical model for strategic network formation that can be estimated with data from … a single network at a single point in time. We model the network formation as a sequential process where in each period …, the characteristics of the potential partner, and on features of the current state of the network, such as whether the two …

We define a general class of network formation models, Statistical Exponential Random Graph Models (SERGMs), that nest …' (including ERGMs) parameters estimated from the observation of a single network are consistent (i.e., become accurate as the … exponentially slow mixing times for many specifications, we show that by reformulating network formation as a distribution over the …
