Extensive research refutes the claim that increasing the minimum wage causes increased unemployment and business closures. (See list below.)
The buying power of the minimum wage reached its peak in 1968 at $10.79, adjusting for inflation in 2015 dollars. The unemployment rate went from 3.8% in 1967 to 3.6% in 1968 to 3.5% in 1969. The next time the unemployment rate came close to those levels was after the minimum wage raises of 1996 and 1997. Business Week observed in 2001, “Many economists have backed away from the argument that minimum wage [laws] lead to fewer jobs.”
Numerous states raised their minimum wages higher than the federal level during the 1997-2007 period the federal minimum wage remained stuck at $5.15. Research by the Fiscal Policy Institute and others showed that states that raised their minimum wages above the federal level experienced better employment and small business trends than states that did not.
A series of rigorous studies by the Institute for Research on Labor and Employment at the University of California, Berkeley, significantly advanced the research on minimum wage employment effects. Minimum Wage Effects Across State Borders compared all neighboring counties in the U.S. located on different sides of a state border with different minimum wage levels between 1990 and 2006 and found no adverse employment effects from higher minimum wages.
The Institute for Research on Labor and Employment’s Spacial Heterogeneity and Minimum Wages: Employment Estimates for Teens Using Cross-State Commuting Zones found “no discernable disemployment effect, even when minimum wage increases lead to relatively large wage changes.” Do Minimum Wages Really Reduce Teen Employment? analyzed the 1990-2009 period (an earlier version analyzed 1990-2007). Carefully controlling for more factors than previous minimum wage studies, the researchers found the answer is no.
In a 2013 report, Why Does the Minimum Wage Have No Discernible Effect on Employment?, the Center for Economic and Policy Research spotlighted two recent meta-studies analyzing the extensive research conducted since the early 1990s; they conclude that "the minimum wage has little or no discernible effect on the employment prospects of low-wage workers. The most likely reason for this outcome is that the cost shock of the minimum wage is small relative to most firms' overall costs and only modest relative to the wages paid to low-wage workers." The Center report explores varied means of adjustment by employers such as increased worker productivity and diminished wage gap between lower and higher paid employees, noting, "But, probably the most important channel of adjustment is through reductions in labor turnover, which yield significant cost savings to employers."
More recent studies on states and cities with higher minimum wages by the Institute for Research on Labor and Employment, Center for Economic and Policy Research, and others continue to show that actual minimum wage increases have not caused job loss.
