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 …

, summary network parameters (e.g., the degree distribution or transitivity index); and (iii) empirical models of strategic … network formation admitting interdependencies in preferences. Current research challenges and open questions are also …

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 … 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 …

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 …

year period, we examine the pattern of adoption of airtime transfers over time. We start by documenting strong network … then seek to narrow down the possible sources of these network effects by distinguishing between network externalities and … and the quality of the product. In contrast, we find that network effects turn negative after first adoption, suggesting …

information both at the level of household pairs and at the level of the network. We also note that the individual level measures … can be interpreted as measures of network centrality. We study risk sharing within these networks and explore whether the …

. Network effects are essential to explaining the joint evolution of the empirical firm size and firm volatility distributions …. We propose and estimate a simple network model of firm volatility in which shocks to customers influence their suppliers …

The adoption and diffusion of inputs in the production network is at the heart of technological progress. What … from a network perspective, starting from a stylized model of network formation. Producers direct their search for new … inputs along vertical linkages, screening the network neighborhood of existing suppliers to identify potentially useful …
