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 model of informal financial networks and present corroborating evidence by studying the role of professional property brokers in the U.S. commercial real estate market. Our model demonstrates how service intermediaries, who do not supply finance themselves, can facilitate their...

We develop a theoretical model of security investments in a network of interconnected agents. Network connections … strategic substitutes. In a general (non-symmetric) network, this implies that underinvestment by some agents will encourage … symmetric or locally tree-like. We also characterize the impact of network structure on equilibrium and optimal investments …

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 …

Past innovation network structures are calculated using citation patterns across technology classes during 1975 …-1994. The interaction of this pre-existing network structure with patent growth in upstream technology fields has strong …
