Abstract: A unique supply chain disruption in the USA created shortages resulting in inflated prices of products regularly sourced from foreign production locations despite their availability at pre-pandemic levels at the US ports. This study uses the 'fishbone' or 'cause and effect' diagram, a graphical tool developed by Ishikawa, to analyse the underlying reasons for this unique disruption. Our analysis reveals that this disruption emerged from the interaction of lingering effects of the COVID-19 pandemic and structural limitations of US West Coast ports. Discussion of factors deemed responsible for the disruption is elucidated along with managerial implications and the study's limitations.

Keywords: supply chain disruption; blockage at US ports; effect of COVID-19; infrastructure challenge and application of fishbone approach. (search for similar items in EconPapers)
