In total, Japan spent $6.3 trillion on construction-related public investment between 1991 and September of last year, according to the Cabinet Office. The spending peaked in 1995 and remained high until the early 2000s, when it was cut amid growing concerns about ballooning budget deficits. More recently, the governing Liberal Democratic Party has increased spending again to revive the economy and the party’s own flagging popularity.
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.
In the United States, it has also led to calls in Congress, particularly by Republicans, not to repeat the errors of Japan’s failed economic stimulus. They argue that it makes more sense to cut taxes, and let people decide how to spend their own money, than for the government to decide how to invest public funds. Japan put more emphasis on increased spending than tax cuts during its slump, but ultimately did reduce consumption taxes to encourage consumer spending as well.
Economists tend to divide into two camps on the question of Japan’s infrastructure spending: those, many of them Americans like Mr. Geithner, who think it did not go far enough; and those, many of them Japanese, who think it was a colossal waste.
Read the rest. The central problem with the “Japan did not spend enough” argument is that, as others have pointed out, it is non-falsifiable. I suspect it is the same argument we will hear Keynesians use in their defense when Obama’s stimulus fails to deliver what he’s promising.
