Congress recently voted to increase the federal minimum wage from $5.15 to $7.25 over a two-year period — a dramatic 40 percent increase. Final action on the minimum wage increase has not yet been cleared due to differences in the Senate bill and the House bill.
But Congress should be reminded that a minimum wage is nothing more than a price control on labor, which is a restriction on economic freedom.
Any nation that raises its minimum wage compromises its economic freedom score in the annual “Index of Economic Freedom” from The Heritage Foundation and The Wall Street Journal. The proposed change could reduce America's labor freedom score in the Index from 92 percent to 87 percent. America, now the fourth freest economy in the world, would drop to sixth place due to this single policy change.
In a free-market economy, prices allocate land, information, capital goods and labor to their highest use. Markets are truly free only if prices are free. For example, a firm that needs more workers signals its need to the labor market by offering a higher wage. Wages are good indicators that direct people to employment and show businesses how to expand. Freely floating prices allocate resources efficiently to places where they will take root and boost economic productivity.
Many types of labor regulations infringe on this market mechanism by disturbing price signals and, therefore, restraining the economic freedom of business owners and workers. One of the most prominent is the minimum wage. By setting a government-specified floor for workers' wages, minimum wage laws tend to disrupt labor supply and demand.
The labor market is not excused from the basic economic principle that artificially high prices cause lower demand. In particular, less skilled workers will suffer. The mismatch between labor supply and labor demand is likely to harm the very people the minimum wage is intended to help. A recent National Bureau of Economic Research study reviewed about 90 empirical papers from the early 1990s to the present. It found that two-thirds of those papers conclude that the effects of the minimum wage are negative.
Further, among the most methodologically rigorous of those papers, "almost all point to negative employment effects." The study also revealed "relatively overwhelming evidence of stronger disemployment" impacts on less-experienced workers.
Of even greater concern, increasing minimum wage is likely to curtail one of the pillars of U.S. international competitiveness, labor freedom. Labor freedom, like property rights and business freedom, is fundamental to a country's overall economic freedom as measured by the Index of Economic Freedom. The Index grades 157 countries' economic freedom, and one of the Index's 10 key components is a labor-freedom factor that measures the ability of workers and businesses to interact without restrictions imposed by the government.
According to the 2007 Index, U.S. labor markets are 92.1 percent free. Raising the minimum wage, which is one of the four elements of the labor freedom factor, will lower the score for U.S. labor freedom. The amount of the drop depends on how the 50 states react, because many have higher local minimum wages and would presumably raise theirs in response to congressional action. The proposed increase in the federal minimum wage is estimated to reduce the overall U.S. labor freedom score by 1.2 to 4.8 percentage points, dropping the labor score potentially as low as 87.3 percent.
America's economy is currently rated as 82 percent free overall. The implications of the 40 percent increase in the minimum wage could drop that score to 81.5 percent free.
Supporters of increasing the minimum wage argue that they do so in order to help poor and less-skilled workers. But government intrusion into the labor market through raising minimum wage generates the same problems that similar interventions produce in other markets. The minimum wage disrupts the natural interaction of supply and demand and leads to inefficient allocations of labor and, eventually, increased unemployment.
Congress should reconsider increasing the minimum wage and look for ways to help American workers by increasing their competitiveness.
