Press Releases | News from EPI: EPI study finds, Wisconsin public-sector workers under-compensated A new Economic Policy Institute study released this week finds that full-time state and local government employees in Wisconsin are undercompensated by 8.2%, when compared to otherwise similar private-sector workers. By using a comprehensive database that is updated monthly by the U.S. Census Bureau and Bureau of Labor Statistics, the study provides an accurate comparison of public- and private-sector compensation in Wisconsin. The analysis, Are Wisconsin Public Employees Over-compensated? by Labor and Employment Relations Professor Jeffrey Keefe of Rutgers University, controls for education, experience, hours of work, organizational size, gender, race, ethnicity, experience, citizenship and disability. The study uses data collected primarily from the National Compensation Survey, and in accordance with standard survey practice, focuses on year-round, full-time public and private-sector employees.
