Firm Size-Wage Premiums : Using Employer Data to Unravel the Mystery

The literature on establishment size-wage effects has consistently shown a positive relationship between the number of employees and workers' wages. While several theories have been offered to explain these outcomes, the use of data with limited employer characteristics make for a dubious connection between theory and results.
