ABSTRACT Freight rates for perishables have long been observed to be extremely variable both across time and within the same time period. Several reasons for this variation have been hypothe- sized, little research has been devoted to the subject area. This study examines the roles of load and shipment characteris- tics, carrier status, and methods of arranging for carriage on rates. The results reveal that load and shipment characteris- tics are the dominant factors in rate determination. Of par- ticular interest is the discovery that the rate structure re- sembles the value of service or commodity value-correlated rate structures commonly found in regulated carriage.
