Four Nations, Four Lessons

As the economy languishes, politicians and pundits are debating what to do next. When we look around the world, it’s hard to find positive role models. But as we search for answers, it is useful to keep in mind those fates that we would like to avoid.

The recent economic histories of four nations are noteworthy: France, Greece, Japan and Zimbabwe. Each illustrates a kind of policy mistake that could, if we are not careful, presage the future of the United States economy. Think of them as the four horsemen of the economic apocalypse.

Let’s start with Zimbabwe. If there were an award for the world’s worst economic policy, it might well have won it several times over the past decade. In particular, in 2008 and 2009, it experienced truly spectacular hyperinflation. Prices rose so fast that the central bank eventually printed 100 trillion-dollar notes for people to carry. The nation has since abandoned using its own currency, but you can still buy one of those notes as a novelty item for about $5 (American, that is).

Some may find it hard to imagine that the United States would ever go down this route. But reckless money creation is apparently a concern of Gov. Rick Perry of Texas, who is seeking the Republican nomination for president. He suggested in August that it would be “almost treasonous” if Ben S. Bernanke, chairman of the Federal Reserve, were to print too much money before the election. Mr. Perry is not alone in his concerns. Many on the right fear that the Fed’s recent policies aimed at fighting high unemployment will mainly serve to ignite excessive inflation.
