An excellent must read article about minimum wages. I usually would not post back to back on the same issue but this is an exception. Enjoy the treat.

Economic View
The Business of the Minimum Wage

I don’t believe that’s because economists care less about the plight of
the poor — many economists are perfectly nice people who care deeply
about poverty and
income inequality.
Rather, economic analysis raises questions about whether a higher
minimum wage will achieve better outcomes for the economy and reduce
poverty.
First, what’s the argument for having a minimum wage at all? Many of my
students assume that government protection is the only thing ensuring
decent wages for most American workers. But basic economics shows that
competition between employers for workers can be very effective at
preventing businesses from misbehaving. If every other store in town is
paying workers $9 an hour, one offering $8 will find it hard to hire
anyone — perhaps not when unemployment is high, but certainly in normal
times. Robust competition is a powerful force helping to ensure that
workers are paid what they contribute to their employers’ bottom lines.
One argument for a minimum wage is that there sometimes isn’t enough
competition among employers. In our nation’s history, there have been
company towns where one employer truly dominated the local economy. As a
result, that employer could affect the going wage for the entire area.
In such a situation, a minimum wage can not only make workers better off
but can also lead to more efficient levels of production and
employment.
But I suspect that few people, including economists, find this argument
compelling today. Company towns are largely a thing of the past in this
country; even Wal-Mart Stores, the nation’s largest employer,
faces substantial competition
for workers in most places. And many employers paying the minimum wage
are small businesses that clearly face strong competition for workers.
Instead, most arguments for instituting or raising a minimum wage are
based on fairness and redistribution. Even if workers are getting a
competitive wage, many of us are deeply disturbed that some hard-working
families still have very little. Though a desire to help the poor is
largely a moral issue, economics can help us think about how successful a
higher minimum wage would be at reducing poverty.
An important issue is who benefits. When the minimum wage rises, is
income redistributed primarily to poor families, or do many families
higher up the income ladder benefit as well?
It is true, as
conservative commentators often point out, that some minimum-wage workers are middle-class teenagers or secondary earners in fairly well-off households. But
the available data suggest
that roughly half the workers likely to be affected by the $9-an-hour
level proposed by the president are in families earning less than
$40,000 a year. So while raising the minimum wage from the current $7.25
an hour may not be particularly well targeted as an anti-poverty
proposal, it’s not badly targeted, either.
A related issue is whether some low-income workers will lose their jobs
when businesses have to pay a higher minimum wage. There’s been a
tremendous amount of research on this topic, and the bulk of the
empirical analysis finds that
the overall adverse employment effects are small.
Some evidence suggests that employment doesn’t fall much because the higher minimum wage
lowers labor turnover,
which raises productivity and labor demand. But it’s possible that
productivity also rises because the higher minimum attracts more
efficient workers to the labor pool. If these new workers are typically
more affluent — perhaps middle-income spouses or retirees — and end up
taking some jobs held by poorer workers, a higher minimum could harm the
truly disadvantaged.
Another reason that employment may not fall is that businesses pass
along some of the cost of a higher minimum wage to consumers
through higher prices.
Often, the customers paying those prices — including some of the diners
at McDonald’s and the shoppers at Walmart — have very low family
incomes. Thus this price effect may harm the very people whom a minimum
wage is supposed to help.
It’s precisely because the redistributive effects of a minimum wage are
complicated that most economists prefer other ways to help low-income
families. For example, the current tax system already subsidizes work by
the poor via an earned-income tax credit. A low-income family with
earned income gets a payment from the government that supplements its
wages. This approach is
very well targeted — the subsidy goes only to poor families — and could easily be made more generous.
By raising the reward for working, this tax credit also tends to
increase the supply of labor. And that puts downward pressure on wages.
As a result,
some of the benefits go to businesses,
as would be the case with any wage subsidy. Though this mutes some of
the direct redistributive value of the program — particularly if there’s
no constraining minimum wage — it also tends to increase employment.
And a job may ultimately be the most valuable thing for a family
struggling to escape poverty.
What about the macroeconomic argument that is sometimes made for raising
the minimum wage? Poorer people typically spend a larger fraction of
their income than more affluent people. So if an increase in the minimum
wage successfully redistributed some income to the poor, it could
increase overall consumer spending — which could stimulate employment
and output growth.
All of this is true, but the effects would probably be small. The
president’s proposal would raise annual income by $3,500 for a full-time
minimum-wage worker. A
recent analysis
found that 13 million workers earn less than $9 an hour. If they were
all working full time at the current minimum — and a majority are not —
the income increase from the higher minimum wage would be only about $50
billion. Even assuming that all of that higher income was redistributed
from the wealthiest families, the
difference in spending behavior
between low-income and high-income consumers is likely to translate
into only about an additional $10 billion to $20 billion in consumer
purchases. That’s not much in a $15 trillion economy.
SO where does all of this leave us? The economics of the minimum wage
are complicated, and it’s far from obvious what an increase would
accomplish. If a higher minimum wage were the only anti-poverty
initiative available, I would support it. It helps some low-income
workers, and the costs in terms of employment and inefficiency are
likely small.
But we could do so much better if we were willing to spend some money. A
more generous earned-income tax credit would provide more support for
the working poor and would be pro-business at the same time. And
pre-kindergarten education, which the president proposes to make
universal, has been shown in
rigorous studies
to strengthen families and reduce poverty and crime. Why settle for
half-measures when such truly first-rate policies are well understood
and ready to go?
