Dynamic Diffusion in Production Networks

Author

Abstract

I show three properties in which a dynamic input-output economy with time to build differs from a static economy: first, a standard result in a Cobb-Douglas production networks is that productivity shocks diffuse downstream while demand shocks diffuse upstream. This fact interacts with the discount rate to generate a potentially quite different aggregate impact in different sectors. With time to build the direction of the diffusion is the opposite, and demand shocks also diffuse downstream. Second, I show that time to build leads to less comovement across sectors. Third, I provide bounds on the recovery time of the economy hit by a shock.
