An improved measure of inter-industry pay differentials

The measurement of inter-industry pay differentials and the resulting use of this information to assess the empirical relevance of different labor market theories have been hampered by the fact that measures of total compensation – as opposed to just wages and salaries – are not available in the datasets traditionally used. We improve upon past measures of inter-industry pay differentials by being the first, to our knowledge, to incorporate microdata on nonwage compensation. Such compensation can easily exceed 40 to 50 percent of wages and thus its inclusion may either diminish or amplify measured industry pay differences. Using the Employer Costs for Employee Compensation (ECEC) data produced by the U.S. Bureau of Labor Statistics, we find that the inclusion of benefits increases industry dispersion by 16 percent when no controls are included and by an even greater 30 percent when controls are included.
