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 …

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 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 …

This paper investigates how the destabilizing of a social network may increase the scope of network externalities … adopt relative to those in other cities. Empirical analysis suggests that the aggregate effect of network externalities on …

In this paper we study consumption network effects. Does the consumption of our peers affect our own consumption? How …, and credible definition of networks than used in previous literature.
