An Empire At Risk

Niall Ferguson poses a brain teaser in an article on the risks of collapse of American hegemony in Newsweek

Now, who said the following? “My prediction is that politicians will eventually be tempted to resolve the [fiscal] crisis the way irresponsible governments usually do: by printing money, both to pay current bills and to inflate away debt. And as that temptation becomes obvious, interest rates will soar.”

Couldn’t have been a world famous Keynesian economist, speaking about a US administration he didn’t like? Could it?Ferguson continues –

Seems pretty reasonable to me. The surprising thing is that this was none other than Paul Krugman, the high priest of Keynesianism, writing back in March 2003. A year and a half later he was comparing the U.S. deficit with Argentina’s (at a time when it was 4.5 percent of GDP). Has the economic situation really changed so drastically that now the same Krugman believes it was “deficits that saved us,” and wants to see an even larger deficit next year? Perhaps. But it might just be that the party in power has changed.

In An Empire at Risk, Ferguson argues that while Ireland, Iceland, Britain and the US all grapple with the same problems – only collapse in the USA will cause serious trauma for the world and it’s current order.

He describes a problem the USA could face, that unfortunately we in Ireland are already familar with –

So here’s another scenario—which in many ways is worse than the inflation scenario. What happens is that we get a rise in the real interest rate, which is the actual interest rate minus inflation. According to a substantial amount of empirical research by economists, including Peter Orszag (now at the Office of Management and Budget), significant increases in the debt-to-GDP ratio tend to increase the real interest rate. One recent study concluded that “a 20 percentage point increase in the U.S. government-debt-to-GDP ratio should lead to a 20–120 basis points [0.2–1.2 percent] increase in real interest rates.” This can happen in one of three ways: the nominal interest rate rises and inflation stays the same; the nominal rate stays the same and inflation falls; or—the nightmare case—the nominal interest rate rises and inflation falls.

Today’s Keynesians deny that this can happen. But the historical evidence is against them. There are a number of past cases (e.g., France in the 1930s) when nominal rates have risen even at a time of deflation. What’s more, it seems to be happening in Japan right now. Just last week Hirohisa Fujii, Japan’s new finance minister, admitted that he was “highly concerned” about the recent rise in Japanese government bond yields. In the very same week, the government admitted that Japan was back in deflation after three years of modest price increases.
