We construct an index of US supply disruptions (US SDI, www.disruptions.supply) based on 200 million import transactions for the US spanning the last decade. Our aggregate index reveals that although there has been a notable improvement in US supply disruptions in 2022, these disruptions...

We associate a dynamical system with input-output networks and study its spectral properties. Specifically, we develop a dynamic production network model featuring adjustment costs of changing inputs and thus gradual recovery from temporary TFP shocks. First, we explicitly solve for the output...

We develop a theory of sectoral fluctuations driven by the propagation of demand shocks along supply chains with heterogeneous time-to-build production. We solve the model in closed form. Downstream producers respond directly to current demand. Upstream producers, due to time-to-build delays,...

A decade into the transition, many of the successor states of the former Soviet Union (FSU) continue to use energy sector quasi-fiscal activities (QFAs), especially low energy prices and the toleration of payment arrears, to provide large implicit and untargeted subsidies. These activities...

We analyze a model of green technological transition along a supply chain. In each layer, a good is produced with a dirty technology, or, if the required "electriffcation" innovation has occurred, with a clean technology which uses the immediate upstream good. We show that the economy is...
