Barack Obama-san

As January 20 nears, Barack Obama’s ambitions for spending on the likes of roads, bridges and jobless benefits keep growing. The latest leak puts the “stimulus” at $1 trillion over a couple of years, and the political class is embracing it as a miracle cure.

Not to spoil the party, but this is not a new idea. Keynesian “pump-priming” in a recession has often been tried, and as an economic stimulus it is overrated. The money that the government spends has to come from somewhere, which means from the private economy in higher taxes or borrowing. The public works are usually less productive than the foregone private investment.

In the Age of Obama, we seem fated to re-explain these eternal lessons. So for today we thought we’d recount the history of the last major country that tried to spend its way to “stimulus” — Japan during its “lost decade” of the 1990s. In 1992, Japanese Prime Minister Kiichi Miyazawa faced falling property prices and a stock market that had sunk 60% in three years. Mr. Miyazawa’s Liberal Democratic Party won re-election promising that Japan would spend its way to becoming a “lifestyle superpower.” The country embarked on a great Keynesian experiment.

Japan’s economy grew anemically over that decade, but as the nearby chart shows, its national debt exploded. Only in this decade, with a monetary reflation and Prime Minister Junichiro Koizumi’s decision to privatize state assets and force banks to acknowledge their bad debts, did the economy recover. Yet recent governments have rolled back Mr. Koizumi’s reforms and returned to their spending habits. But Japan does have better roads.

Now we’re told that a similar spending program — a new New Deal — will revive the U.S. economy. How do you say “good luck” in Japanese?
