ECONOMY: Why We Trade
By Russell Roberts
Imports bad, exports good—how long must we endure this skewed
logic? By Russell Roberts.
To hear most politicians talk, you’d think that exports are the key to a country’s
prosperity and that imports are a threat to its way of life. Trade
deficits—importing more than we export—are portrayed as the road to
ruin. U.S. presidential hopefuls Hillary Clinton and Barack Obama want
to get tough with China because of “unfair” trading practices that help
China sell products cheaply. Former Republican candidate Mitt Romney
argued that trade is good because exports benefit the average American.
Politicians are always talking about the necessity of other countries’ opening
their markets to American products. They never mention the virtues of
opening U.S. markets to foreign products.
This perspective on imports and exports is called mercantilism. It goes
back to the fourteenth century and has about as much intellectual rigor as
alchemy, another landmark of the pre-Enlightenment era.
The logic of “exports good, imports bad” seems straightforward at first—
after all, when a factory closes because of foreign competition, there seem
to be fewer jobs than there otherwise would be. Don’t imports cause factories
to close? Don’t exports build factories?
But is the logic really so clear? As a thought experiment, take what would
seem to be the ideal situation for a mercantilist. Suppose we only export
and import nothing—the ultimate trade surplus. So we work and use raw
materials and effort and creativity to produce stuff for others without getting anything in return. There’s another name for that. It’s called slavery.
How can a country get rich working for others?
Then there’s the mercantilist nightmare: we import from abroad, but
foreigners buy nothing from us. What would the world be like if every
morning you woke up and found a Japanese car in your driveway, Chinese
clothing in your closet, and French wine in your cellar? All at no cost. Does
that sound like heaven or hell? The only analogy I can think of is Santa
Claus. How can a country get poor from free stuff? Or cheap stuff? How
do imports hurt us?
We don’t export to create jobs. We export so we can have money to buy
the stuff that’s hard for us to make—or at least hard for us to make as
cheaply. We export because that’s the only way to get imports. If people
would just give us stuff, then we wouldn’t have to export. But the world
doesn’t work that way.
It’s the same in our daily lives. It’s great when people give us presents—
a loaf of banana bread or a few tomatoes from the garden. But a new car
would be better, or even just a cheaper car. But the people who bring us cars and clothes and watches and shoes expect something in return. That’s
OK. That’s the way the world works. But let’s not fool ourselves into thinking
that the goal of life is to turn away bargains from outside our house or
outside our country because we’d rather make everything ourselves. Selfsufficiency
is the road to poverty.
Chicken Little

And imports don’t destroy jobs. They destroy jobs in certain industries.
But because trade allows us to buy goods more cheaply than we otherwise
could, resources are freed up to expand existing opportunities and to create
new ones. That’s why we trade—to leverage the skills of others who can
produce things more effectively than we can, freeing us to make things we
otherwise wouldn’t be able to afford.
The United States has run a merchandise trade deficit every year since
1976. It has also added more than 50 million jobs during that time. Per
capita income, corrected for inflation, is up more than 50 percent since
1976. The scaremongers who worry about trade deficits talk about stagnant
wages, but they ignore fringe benefits (an increasingly important part
of worker compensation) and fail to measure inflation properly.
In a recent Republican presidential debate, one of the moderators said
that since 1989, the United States had lost 5 million jobs to foreign trade.
He wanted to know what the candidates were going to do about it.
We don’t export to create jobs. We export so we can earn money to buy
the stuff that’s hard for us to make—or at least hard to make cheaply. We
export because that’s the only way to get imports.
I have no idea how you measure that number, but the implication was
that 5 million lost jobs over eighteen years is a big number. Five million is
a large number if we’re talking about the number of pennies I have to carry
in my pockets. It’s a big number if we’re talking about the number of people
coming to my kid’s birthday party. But it’s a very small number when
you’re talking about job destruction and the job creation that follows in a
dynamic economy.
On the first Friday of every month, the U.S. Bureau of Labor Statistics
produces an estimate of how many new jobs are added to the U.S. economy.
That’s the net change, the gains minus the losses. The bureau also estimates quarterly gross job changes, the absolute number of jobs created and
destroyed. In the fourth quarter of 2006, there were 7.7 million jobs created
and 7.2 million jobs lost. That happens every quarter when there isn’t
a recession—that’s how you add 50 million jobs over three decades.
Five million jobs lost over 18 years? Every three months, the U.S. job
market more than makes up for those losses.
The goal is not to turn away bargains from outside our country because
we’d rather make everything ourselves. Self-sufficiency is the road to
poverty.
Trade is just one economic force that creates and destroys jobs. Tastes
change. Innovation makes workers more productive. Some industries shrink.
Others expand. Some disappear. New industries get created. Joseph Schumpeter
called it creative destruction, and he understood that it is the underlying
mechanism that transforms our standard of living for the better.
Let’s stop trying to scare people with the Chinese threat to our economy.
The world would be a better and more peaceful place if we stopped measuring
the trade deficit. But if we’re going to measure it, the least we can
do is talk about it sensibly.
