Abstract
In an abundance of literature written before the passage of the Motor Carrier Act (MCA) of 1980, researchers discussed and often debated the anticipated effects of regulatory reform on shippers and carriers. Since the passage of the MCA of 1980, most of the studies have focused on carriers, with little research on the effects of deregulation from the shippers' perspective. The results of this study suggest that service attributes appear to be more important factors than pricing attributes in the selection of national common carriers. The study also indicates that both carriers and shippers were in a period of adjustment following the policy changes.
