Economist vs Economist: on Minimum Wage Hikes


Like Spy Vs Spy in the old Mad magazine.

(This post is taken from the heavy lifting David R. Henderson performed.)

Here’s an economist talking about the textbook view of the minimum wage, and how we should take the (in)famous Card & Krueger results with a grain of salt:

So what are the effects of increasing minimum wages? Any Econ 101 student can tell you the answer: The higher wage reduces the quantity of labor demanded, and hence leads to unemployment. This theoretical prediction has, however, been hard to confirm with actual data. Indeed, much-cited studies by two well-regarded labor economists, David Card and Alan Krueger, find that where there have been more or less controlled experiments, for example when New Jersey raised minimum wages but Pennsylvania did not, the effects of the increase on employment have been negligible or even positive. Exactly what to make of this result is a source of great dispute. Card and Krueger offered some complex theoretical rationales, but most of their colleagues are unconvinced; the centrist view is probably that minimum wages “do,” in fact, reduce employment, but that the effects are small and swamped by other forces.

What is remarkable, however, is how this rather iffy result has been seized upon by some liberals as a rationale for making large minimum wage increases a core component of the liberal agenda…Clearly these advocates very much want to believe that the price of labor–unlike that of gasoline, or Manhattan apartments–can be set based on considerations of justice, not supply and demand, without unpleasant side effects…

Now to me, at least, the obvious question is, why take this route? Why increase the cost of labor to employers so sharply, which–Card/Krueger notwithstanding–must pose a significant risk of pricing some workers out of the market, in order to give those workers so little extra income? Why not give them the money directly, say, via an increase in the tax credit?

In short, what the living wage is really about is not living standards, or even economics, but morality. Its advocates are basically opposed to the idea that wages are a market price–determined by supply and demand, the same as the price of apples or coal.

Just today, Paul Krugman offers a decidedly different take on how we should interpret the Econ 101 textbooks and the empirical evidence:

So what should you know? First, as John Schmitt (pdf) documents at length, there just isn’t any evidence that raising the minimum wage near current levels would reduce employment. And this is a really solid result, because there have been a *lot* of studies. We can argue about exactly why the simple Econ 101 story doesn’t seem to work, but it clearly doesn’t — which means that the supposed cost in terms of employment from seeking to raise low-wage workers’ earnings is a myth.

So a minimum wage increase isn’t some kind of counsel-of-despair way to help workers a bit in a dysfunctional political scene (although there’s that too); it’s actually good policy.

At this point, surely I don’t need to tell you guys who wrote the first block quote above, do I? It was from 1998.

P.S. Yes, in the first block quote, he’s talking about a “living wage” proposal that means a large increase in the minimum wage, whereas in the second he’s talking about a more modest increase. If you think his readers are picking up on all those nuances, and that this is a consistent economic perspective, you have more faith in humanity than I do.

One response to “Economist vs Economist: on Minimum Wage Hikes

  1. It’s hard getting a handle on the real world impacts of minimum wage increases. I would definitely agree that a sharp increase would result in negative effects. But like it was mentioned above this is a modest increase.

    I guess my perspective is;
    1) This is not an immediate increase but incremental (over 2 years)
    2) It’s a small-moderate ~24% increase or $1.75/hr
    3) Whatever negatives that might be result, if any, from this, the equilibrium will again be reached.
