I am disappointed in Greg Mankiw.
He won't say "no":
Financial Lessons From Four Nations: 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….
To be sure, the bond market doesn’t seem particularly worried about the solvency of the federal government. It is still willing to lend to the United States at low rates of interest. But the same thing was true of Greece four years ago. Once the bond market starts changing its mind, the verdict can be swift, and can lead to a vicious circle of rising interest rates, increasing debt service and budget deficits, and falling confidence…
When some are "crying 'Fire! Fire!' in Noah's Flood", a reality-based economist does not say: "Gee. It might be bone-dry in a decade. We should get ready!" A reality-based economist says: "Grab a bucket and a sandbag!"
