Examining industry effects for truck drivers

Disaggregating truck drivers by industrial classification, rather than usin g a private carriage for hire distinction, a significant wage gap is found between drivers in trucking services and drivers in all other industries. T he premium for drivers in trucking services is largest relative to drivers in wholesale and retail trade and agriculture, who are most likely to be tr ue private carriage drivers. Drivers in construction and mining, less likel y to meet the true definition of private carriage, have smaller wage disadv antages. This suggests that the wage gap between for-hire and private carri age drivers may be underestimated in other research.
