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 then estimate … consumer willingness-to-pay for network breadth, which varies by age. 60-year-olds value the broadest network approximately … $1200-1400/year more than the narrowest network, while 30-year-olds value it about half as much. Consumers place additional …

We study the direct and spillover effects of local state capacity using the network of Colombian municipalities. We … model the determination of local and national state capacity as a network game in which each municipality, anticipating the … (using GMM, simulated GMM or maximum likelihood). To do so we exploit both the structure of the network of municipalities …

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 …

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 …

Focusing on a multi sector economy linked through a supply network, we show how structural properties of … the supply network determine both whether aggregate volatility disappears as the number of sectors increases (i … aggregate output from its mean) to sector-specific volatility and to the structural properties of the supply network …
