Arent barges too slow to effectively move commodities in a just-in-time economy?
Commodities that are suitable for shipping by barge are not the types of commodities that are required by the just-in-time economy; rather they are bulk commodities such as coal, aggregate, sand, rock, steel products, agricultural products, fertilizer, wood products, petroleum products, etc. These are not just-in-time commodities. These are commodities that are stockpiled for use. River transportation is the logical and efficient method of transporting these commodities.
