Resumen

The author’s survey leads him to conclude that the average cost curve declines sharply to an output level of about 6.8 million ton-miles per annum, and rises gradually beyond that. The trucking industry is dominated by firms above that size as a result of the policy of the US Interstate Commerce Commission.
