Abstract: We provide a general characterization of diffusion processes, allowing to analyze both risk-sharing and contagion at the same time. We show that interdependencies are beneficial when the economic environment is favorable, and detrimental when the economic environment deteriorates. The risk of contagion increases the volatility of outcome and thus reduces the ability of the network to provide risk-sharing.
