NEW STUDY: Wisconsin Prevailing Wage Repeal Reduced Wages, Exported Jobs and Tax Dollars Out of State, and Failed to Deliver Any Cost Savings

No state that has repealed prevailing wage has seen the benefits claimed by politicians


La Grange, Illinois:  For the third time in as many years, state-level research conducted by the nonpartisan Midwest Economic Policy Institute (MEPI) has shown that the repeal of state prevailing wage laws has failed to produce any of the cost savings that proponents promised, and has instead resulted in lower wages for workers, weakened apprenticeship systems, less overall bid competition, and more tax dollars being exported out-of-state.

Read the Report, “The Effects of Repealing Prevailing Wage in Wisconsin: Impacts on Ten Construction Market Outcomes.”

Analyzing data from the U.S. Census Bureau, U.S. Department of Labor, and Wisconsin Department of Transportation, the report was authored jointly by researchers from the Midwest Economic Policy Institute and Colorado State University-Pueblo.  The study findings are consistent with pre-repeal analyses of Wisconsin’s construction sector published by Smart Cities Prevail and the State of Wisconsin’s Legislative Fiscal Bureau, as well as recent reports on other state-level prevailing wage repeals which showed similarly negative impacts in Indiana (2018) and West Virginia (2019).

“Politicians promised Wisconsin taxpayers that eliminating local minimum wage standards on public construction projects would save money and improve bid competition,” said study co-author and MEPI Policy Director Frank Manzo IV.  “But repeal has delivered neither.  Worse, it has functioned as a jobs program for businesses and workers from outside of Wisconsin, while slashing blue-collar workers’ wages and weakening the state’s construction industry as a whole.”

Specifically, the report examined the per-mile cost of state highway projects both before and after the 2017 repeal of Wisconsin’s prevailing wage law.  The data shows that the inflation-adjusted per-mile highway cost has increased by $52,000 following repeal of prevailing wage. Highway projects that did not receive any federal support were also more expensive per mile after repeal of prevailing wage.

Despite the lack of cost savings, the data shows that inflation-adjusted Wisconsin construction worker incomes declined by over 6%– or more than $2,600 per year– and their likelihood of being covered by an employer-provided health insurance plan shrank by 4% after repeal.  Instead, the research shows that the pay of private construction CEOs in Wisconsin grew by an average of 54% after repeal– or more than $93,000 per year– while the costly problem of worker turnover in the heavy and highway construction sector grew by 8% and cost overruns also worsened.

“The actual observed changes in public construction spending since repeal of prevailing wage in Wisconsin underscore the longstanding academic consensus that the substitution of high-skilled local workers by lower-skilled, lower-wage, nonlocal workers does not produce cost savings,” said study co-author and CSU-Pueblo Economist Dr. Kevin Duncan.  “Instead, it creates new inefficiencies in the form of workforce turnover, quality, cost overruns, and safety problems.  And this does not even include the added cost shown in prior research that lower wages for construction workers increase reliance on public assistance programs.”

Researchers added that the lack of cost savings is magnified by the damage that prevailing wage repeal has done to Wisconsin’s economy and construction industry.  According to project data from the Wisconsin Department of Transportation, the number of highway construction projects being awarded to firms from out-of-state has exploded by 60% since repeal– tens of millions of dollars that would have otherwise been invested in workers and businesses inside the Badger State.  Overall bid competition has also shrunk by 16%.  

Because prevailing wage laws also promote long-term investments in workforce training, the study suggests that Wisconsin’s repeal has also created new burdens for its construction industry.  Between 2016 and 2019, growth in the number of Wisconsinites completing registered apprenticeship programs has lagged neighboring states with strong prevailing wage laws by 25%.  The diversity of the state’s construction workforce also changed significantly, with the share people of color in the trades lagging neighboring states and the number of Wisconsin women working as construction workers dropping by 32% relative to neighboring states.

“A strong Wisconsin economy relies on a strong construction industry, and the industry relies on a stable supply of skilled workers,” added MEPI Policy Analyst and study co-author Jill Gigstad.  “By all accounts, repeal of prevailing wage in Wisconsin has functioned as a low-wage jobs program for businesses in other states, while eroding the Wisconsin construction industry’s ability to train or compete for the skilled workforce it needs.”
