Trade Costs, Time, and Supply Chain Reliability
SHARE THIS PAGE
This paper uses measures of international transport time in median and standard deviation based on shipment-level data from the Universal Postal Union, to analyze the effect of time on trade costs. The results show that median shipping times increase trade costs by a substantial amount. The determinants of shipping times are also analyzed and find that geographical distance is the most reliable indicator of median time and uncertainty, with logistics performance also playing a role in determining shipment times.
