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 …

An implication is that interpretations evolve within a network. For … many network structures, social learning mutes reactions to data: the exchange of models leaves beliefs closer to priors …
