Raise That Wage
By PAUL KRUGMAN
President Obama laid out a number of good ideas in his State of the Union address. Unfortunately, almost all of them would require spending money — and given Republican control of the House of Representatives, it’s hard to imagine that happening.
Nutshell: More ideas require more spending money
One major proposal, however, wouldn’t involve budget outlays: the president’s call for a rise in the minimum wage from $7.25 an hour to $9, with subsequent increases in line with inflation. The question we need to ask is: Would this be good policy? And the answer, perhaps surprisingly, is a clear yes.
Nutshell: Rise in minimum wage is a good policy
Why “surprisingly”? Well, Economics 101 tells us to be very cautious about attempts to legislate market outcomes. Every textbook — mine included — lays out the unintended consequences that flow from policies like rent controls or agricultural price supports. And even most liberal economists would, I suspect, agree that setting a minimum wage of, say, $20 an hour would create a lot of problems.
Nutshell: Legislating market outcomes have consequences
But that’s not what’s on the table. And there are strong reasons to believe that the kind of minimum wage increase the president is proposing would have overwhelmingly positive effects.
Nutshell: Rise in minimum wage has great benefits
First of all, the current level of the minimum wage is very low by any reasonable standard. For about four decades, increases in the minimum wage have consistently fallen behind inflation, so that in real terms the minimum wage is substantially lower than it was in the 1960s. Meanwhile, worker productivity has doubled. Isn’t it time for a raise?
Nutshell: Minimum wage has been low for a while
Now, you might argue that even if the current minimum wage seems low, raising it would cost jobs. But there’s evidence on that question — lots and lots of evidence, because the minimum wage is one of the most studied issues in all of economics. U.S. experience, it turns out, offers many “natural experiments” here, in which one state raises its minimum wage while others do not. And while there are dissenters, as there always are, the great preponderance of the evidence from these natural experiments points to little if any negative effect of minimum wage increases on employment.
Nutshell: Rarely any negative effects on raising minimum wage
Why is this true? That’s a subject of continuing research, but one theme in all the explanations is that workers aren’t bushels of wheat or even Manhattan apartments; they’re human beings, and the human relationships involved in hiring and firing are inevitably more complex than markets for mere commodities. And one byproduct of this human complexity seems to be that modest increases in wages for the least-paid don’t necessarily reduce the number of jobs.
Nutshell: Increase in wages don’t reduce jobs
What this means, in turn, is that the main effect of a rise in minimum wages is a rise in the incomes of hard-working but low-paid Americans — which is, of course, what we’re trying to accomplish.
Nutshell: Rising minimum wage effects incomes of low-paid Americans
Finally, it’s important to understand how the minimum wage interacts with other policies aimed at helping lower-paid workers, in particular the earned-income tax credit, which helps low-income families who help themselves. The tax credit — which has traditionally had bipartisan support, although that may be ending — is also good policy. But it has a well-known defect: Some of its benefits end up flowing not to workers but
