Value and Supply Chains in International Trade. Puerto Rico Amidst Disasters, Captures and Leakages

This research introduces the Chain-Business-Trade mapping method, integrating import-export and Bill of Lading data for supply chain analysis. Two quantitative studies, employing Proof of Concept and Pilot Project approaches, focused on identifying alternative sources for critical imports during disasters and assessing Puerto Rico's alignment with America’s Supply Chains priorities. Qualitative methods contextualized findings, addressing international trade constraints and value leakages caused by the US Jones Act. During import disruptions, the Greater Caribbean emerged as a vital alternative network for Puerto Rico, with Mexico, the Dominican Republic, Panama, and the US Virgin Islands playing crucial roles. Puerto Rico's prominence in lithium supply chains (exporting 90% of pacemakers) and pharmaceuticals, aligned with America’s Supply Chains priorities, highlights the impact of international trade constraints on supply chains. The study emphasizes the need for comprehensive mapping and adaptive strategies, noting challenges due to the absence of dedicated institutions for informed decisionmaking.
