Japan’s big-works stimulus is a lesson — in how to spend money with very little return:
The Hamada Marine Bridge soars majestically over this small fishing harbor, so much larger than the squid boats anchored below that it seems out of place.And it is not just the bridge. Two decades of generous public works spending have showered this city of 61,000 mostly graying residents with a highway, a two-lane bypass, a university, a prison, a children’s art museum, the Sun Village Hamada sports center, a bright red welcome center, a ski resort and an aquarium featuring three ring-blowing Beluga whales.
Nor is this remote port in western Japan unusual. Japan’s rural areas have been paved over and filled in with roads, dams and other big infrastructure projects, the legacy of trillions of dollars spent to lift the economy from a severe downturn caused by the bursting of a real estate bubble in the late 1980s. During those nearly two decades, Japan accumulated the largest public debt in the developed world — totaling 180 percent of its $5.5 trillion economy — while failing to generate a convincing recovery.
Now, as the Obama administration embarks on a similar path, proposing to spend more than $820 billion to stimulate the sagging American economy, many economists are taking a fresh look at Japan’s troubled experience.
I shudder to think that this is not obvious to everyone:
“It is not enough just to hire workers to dig holes and then fill them in again,” said Toshihiro Ihori, an economics professor at the University of Tokyo. “One lesson from Japan is that public works get the best results when they create something useful for the future.”
People don’t like to accept the short-term pain of letting some businesses fail:
In the end, say economists, it was not public works but an expensive cleanup of the debt-ridden banking system, combined with growing exports to China and the United States, that brought a close to Japan’s Lost Decade. This has led many to conclude that spending did little more than sink Japan deeply into debt, leaving an enormous tax burden for future generations.
Some economists — those popular with politicians, I suppose — claim that Japan’s stimulus would have worked if they’d just spent more. Others recognize the whole thing as a waste:
Dr. Ihori of the University of Tokyo did a survey of public works in the 1990s, concluding that the spending created almost no additional economic growth. Instead of spreading beneficial ripple effects across the economy, he found that the spending actually led to declines in business investment by driving out private investors. He also said job creation was too narrowly focused in the construction industry in rural areas to give much benefit to the overall economy.
