Abstract or Summary
  • The U.S. trucking industry was deregulated with implementation of the Motor Carrier Act of 1980. After deregulation, increased concentration was observed in the general freight segment of the industry. The purpose of this study was to examine structural differences in general freight commodity carriers and to help explain the increased concentration. Cost functions were estimated for large and small carriers in order to see whether or not size related advantages exist. Although the hypothesis of constant returns to scale could not be rejected, significant structural differences were found between large and small carriers. The results imply that the services provided by large and small carriers are different. Presence of "economies of integration and "economies of route density" for large firms indicate the possibility of oligopoly in the general freight commodity trucking.
