This study shows how import and export shocks propagate through domestic supply chains using actual Japanese supply-chain data and a world input-output table (WIOT) based on firm-level agent-based simulations. We propose three different models with which to connect the domestic firms to a WIOT....

This study quantifies the economic effect of a possible lockdown of Tokyo to prevent spread of COVID-19. The negative effect of the lockdown may propagate to other regions through supply chains because of shortage of supply and demand. Applying an agent-based model to the actual supply chains of...

Social and economic networks can be a channel of negative shocks and thus deteriorate resilience and sustainability of our society. This study focuses on supply chains, or supplier--customer networks of firms and examines how production losses caused by natural disasters propagate to and persist...

This study shows how import and export shocks propagate through domestic supply chains by using actual Japanese supply chain data and a world input-output table based on firm-level agent-based simulations. We propose three different models to connect the domestic firm-level supply chain to the...

To prevent the spread of COVID-19, many cities, states, and countries have `locked down', restricting economic activities in non-essential sectors. Such lockdowns have substantially shrunk production in most countries. This study examines how the economic effects of lockdowns in different...

In order to prevent the spread of COVID-19, governments have often required regional or national lockdowns, which have caused extensive economic stagnation over broad areas as the shock of the lockdowns has diffused to other regions through supply chains. Using supply-chain data for 1.6 million...
