This overwhelming consensus relies not just on the latest Congressional Budget Office report (which projects a 500,000 loss of job growth from Obama’s proposed 40 percent minimum wage hike), but also from an impressive collection of empirical studies and, ultimately, the core theoretical principle that downward-sloping demand curves are a universal phenomenon: Higher prices reduce quantity demanded. The only interesting question is how large the trade-off is, not whether it exists at all.
Raising the minimum wage from $7.25 to $8 wouldn’t cause many job losses. That’s because market wages have moved up since 2009, when the $7.25 floor was implemented. Even McDonald’s, the current target of minimum-wage protests, pays entry workers at least a buck more than the federal minimum. Only an “effective” wage hike -- one that exceeds market-based wages -- actually increases wages or causes job losses. Obama’s increase to $10.10 for the federal minimum more than qualifies as an effective wage hike and will surely lead to fewer jobs.
In assessing those losses, several facts are relevant. First, nearly everyone starts out in a minimum wage job. Second, few people stay at minimum-wage jobs very long; they move up the wage scale quickly with experience and employer references. Third, a majority of both teen and adult minimum-wage workers live in households with other, higher-wage workers. Single moms who hold minimum-wage jobs (the favorite focus of the popular media) stay neither single moms nor at minimum wage jobs very long.
All of this means that an effective wage hike will delay labor-market entry for teens, immigrants and other low-skilled workers who need access to that first step on America’s mobility ladder. So, there is a downside to minimum-wage hikes.
That doesn’t preclude raising the federal minimum. As noted above, it’s a trade-off issue: Will the gain to workers who get higher wages outweigh the loss to workers who confront diminished job opportunities? That’s a policy question that must be answered with empirical data and social priorities.
Science, not opinion polls, should guide decisions on minimum-wage policy. If the president insists on using opinion polls to fashion policy, he should focus on the Gallup poll that says only 40 percent of America approves the way he is handling the economy.
