Abstract

The ability to respond to supply chain disruptions efficiently and effectively is a highly sought after capability, particularly in light of recent events such as the COVID-19 pandemic, geopolitical conflicts, and major natural disasters. These events have led researchers, practitioners, and policymakers to ask: how can we better use our resources to respond to supply chain disruptions? This dissertation examines responses to the three main types of supply chain disruptions: operational disruptions, geopolitical disruptions, and natural disasters. The first study examines how US importers adjust between air and containerized transportation in response to shipment delays and abnormally high demand from the COVID-19 pandemic. The second study analyzes the “Out-of-China” effect and how US importers have geographically diversified their supply chains into multiple countries in light of rising geopolitical uncertainty. Finally, the third study examines price and volume adjustments in the trucking spot market as a response to hurricane landfalls. The research questions are investigated with multiple archival data sources from public and private providers. The new insights generated herein advance theory, practice, and public policy.
