Firm-level propagation of shocks through supply-chain networks
Social and economic networks can be a channel of negative shocks and thus deteriorate resilience and sustainability in societies. This study focuses on supply chains, or supplier–customer networks ofExpand

Propagation of Negative Shocks Through Firm Networks: Evidence from Simulation on Comprehensive Supply-Chain Data
This paper examines how negative shocks due to, for example, natural disasters, propagate through supply chains, applying a simulation technique to actual data on supply chains of Japanese firms. WeExpand

The propagation of economic impacts through supply chains: The case of a mega-city lockdown to prevent the spread of COVID-19
This study quantifies the economic effect of a possible lockdown of Tokyo to prevent the spread of COVID-19. The negative effect of such a lockdown may propagate to other regions through supplyExpand

The Propagation of the Economic Impact through Supply Chains: The Case of a Mega-City Lockdown against the Spread of COVID-19
TLDR
We find that when Tokyo is locked down for a month, the indirect effect on other regions would be twice as large as the direct effect on Tokyo, leading to a total production loss. Expand
