1. Both sides of the debate believe they are arguing in defense of the poor. Most people who support or oppose minimum wage laws and/or increases share a common objective — helping the working poor. Because both sides have noble intentions, the merits of the debate over minimum wage laws and minimum wage increases should be based on empirical evidence that it will actually help, rather than harm, the poor.
2. Economists disagree about the effects of small increases in minimum wages. It’s true that economists disagree about the effects of the minimum wage on employment and the living standards of minimum wage earners. But almost all of the disagreement is about relatively small increases (less than 20%). Almost all economist agree that significant increases to the minimum wage or attempts to bring it in line with a “living wage” (e.g., $12-15 an hour) would lead to significant increases in unemployment. (President Obama’s proposal would only increase the federal minimum wage by $1.75 an hour.)
3. The primary argument for minimum wage increase is that is increases the value of the worker’s labor. — The efficiency wage theory of labor holds that higher real wages improve labor productivity by reducing worker turnover and the associated costs of hiring and training new workers, by reducing the incentive for workers to unionize, and by increasing the opportunity cost of being fired—thereby giving the worker incentive to be more productive. Under this view, small increases to the minimum wage will have no deleterious employment effects.
4. The primary argument against minimum wage increases is that it discriminates against those who have low-skills. Milton Friedman once described the minimum wage as a requirement that “employers must discriminate against people who have low skills.” As Anthony Davies explains, “the minimum wage prevents some of the least skilled, least educated, and least experienced workers from participating in the labor market because it discourages employers from taking a chance by hiring them. In other words, workers compete for jobs on the basis of education, skill, experience, and price. Of these factors, the only one on which the lesser-educated, lesser-skilled, and lesser-experienced worker can compete is price.”
5. The minimum wage redistributes wealth from the low-skilled poor to the more skilled working poor and middle class. Many supporters of minimum wage increases mistakenly believe that increases in wage rates are transfers of wealth from employers and investors to the workers. But as Anthony Davis explains, the money to pay for the increased wage must come from at least one of four places: higher prices for consumers, lower returns to investors, lower prices to suppliers, or a reduced work-force. Empirical research has shown that the primary effect of minimum wage increases is reduced employment, which essentially transfers the wealth (in unearned wages) from the less skilled to the more skilled working poor and middle-class teenagers.
