Global Supply Chain Pressure Index: March 2022 Update
Supply chain disruptions continue to be a major challenge as the world economy recovers from the COVID-19 pandemic. In a January post, we presented the Global Supply Chain Pressure Index (GSCPI) as a parsimonious global measure that encompasses several indicators used to capture supply chain disruptions. The main purpose of this post is to provide an update of the GSCPI through February 2022. In addition, we use the index’s underlying data to discuss the drivers of recent moves in the GSCPI. Finally, these data are used to create country-specific supply chain pressures indices.

Multimodal Transport Networks
We examine the economic and environmental impacts of improvements and disruptions in multimodal transport networks. Our quantitative spatial equilibrium model incorporates routing over multiple modes and congestion at intermodal terminals. We estimate a modal substitution elasticity with highway and rail data and a terminal congestion elasticity with vessel-positioning data. Calibrated to the US freight network, our model identifies key bottlenecks and quantifies $300 million–$700 million in additional real GDP gains from intermodal terminal improvements. These gains are 2.5 times higher ...
