Earlier this year, Gene Sperling gave a speech about why
subsidizing manufacturing is good policy, not a market distortion that is more
likely to do harm than good net net. His
main point was about positive externalities.
Since externalities are a subject that is near and dear to me and a
frequent topic of this blog, I put some serious thought in to his message.
Quick basic background.
There are two reasons for sticking to free market principles and two
reasons to violate them. If you are a
libertarian by religion, then there is never a reason to deviate even a
little. When it is a religion – well,
‘nuf said. On the other side, we look
for externalities. When a person or
organization is able to get the benefits of an operation but pass off the costs
onto someone else, they gain an unfair advantage. In these cases it makes economic sense for
society to add those costs back on through regulation, taxes, or other
mechanism. This is where environment
regulations, labor laws, disclosure rules, accounting standards, etc come
in.
And when a person or organization’s acts create positive
results for society, it makes economic sense for society to encourage it
through subsidies, tax credits, and regulations.
This is where the earned income tax credit and charitable contribution
tax deduction come in.
The problem is that when government intervenes, they often
screw it up. For decades, government
thought the mortgage deduction had positive externalities because homeowners were more likely to keep up the house and the neighborhood. But they didn't see the negative externalities and unintended consequences which magnified the real
estate bubble and subsequent burst. Government industrial
policy often picks specific winners and losers, which skews the market. Corn
subsidies and oil exploration tax credits come to mind. It is better to create more general
interventions like an R&D tax credit that is open to every business in any
industry and any domain.
So where does manufacturing come in? If the government supports manufacturing over
other kinds of business (service, agriculture, natural resources, science),
will that create a distorted market and/or are there positive externalities
that justify the distortion? Gene
Sperling suggested that there are. Manufacturing
creates positive externalities in the form of innovation, spin-off jobs,
supplier jobs, new technology expertise, and more. This happens in greater degree than in other sectors and
therefore justifies the distorting nature of a targeted subsidy.
The problem is when lobbyists get their hands on the
final regulations and skew the benefits towards one manufacturing sector over
another. Cars over trains. Tablets over ultrabooks. OLED lights over fluorescents. Or whatever. This often skews the market to the point where the negatives outweigh the positives.
My thoughts on this won’t surprise any of my regular
followers. The idealist in me knows that
Sperling is correct in theory and that supporting manufacturing could lead to these
positive externalities. But the realist
in me knows that it not going to happen quite as purely as it should. And the result might not be net net
positive. Shame too, because we could use a good boost to jobs right now.
