Using large and comprehensive micro-level datasets, this project examines the effects of the COVID-19 pandemic, the trade war, and Brexit on international trade, foreign investment, and supply chains. We explore how these exogenous shocks affect business activities, transmit through international supply chains and buyer-supplier linkages, and propagate to the whole economy. Specifically, combining information on buyer-supplier linkages with confidential government surveys on the business activities of Japanese firms at home and abroad, we construct measures of firm-specific upstreamness and firm-level subjective uncertainty to empirically analyze the relationship between the exogenous shocks, uncertainty, and supply chains. Furthermore, various topics including the formation and development of supply chains, multinational enterprises and structural change will also be addressed in this project. The empirical findings are expected to provide evidence-based policy implications for the formation and re-evaluation of global supply chains.
