"You are not here to tell me what to
do. You are here to tell me why I have done what I have already decided to
do," Montagu Norman, the Bank of England’s longest-serving governor (1920-1944),
is reputed to have once told his economic adviser. Today, thankfully,
central banks aim to be more transparent in their decision making, as well as
more rational. But achieving either of these things is not always easy.
With the most laudable of intentions, the Federal Reserve, America’s
central bank, may be about to take a step that could backfire.
Unlike the Fed, many other central banks have long declared explicit
inflation targets and then set interest rates to try to meet these. Some
economists have argued that the Fed should do the same. With Alan
Greenspan, the Fed’s much-respected chairman, due to retire next year-after a
mere 18 years in the job-some Fed officials want to adopt a target, presumably
to maintain the central bank’s credibility in the scary new post-Greenspan era.
The Fed discussed such a target at its February meeting, according to
minutes published this week. This sounds encouraging. However, the
Fed is considering the idea just when some other central banks are beginning to
question whether strict inflation targeting really works.
At
present centra1 banks focus almost exclusively on consumer-price indices.
On this measure Mr. Greenspan can boast that inflation remains under
control. But some central bankers now argue that the prices of assets,
such as houses and shares, should also somehow be taken into account. A
broad price index for America which includes house prices is currently running
at 5.5%, its fastest pace since 1982. Inflation has simply taken a different
form.
Should central banks also try to curb increases in such
asset prices Mr. Greenspan continues to insist that monetary policy should not
be used to prick asset-price bubbles. Identifying bubbles is difficult,
except in retrospect, he says, and interest rates are a blunt weapon: an
increase big enough to halt rising prices could trigger a recession. It is
better, he says, to wait for a housing or stockmarket bubble to burst and then
to cushion the economy by cutting interest rates-as he did in 2001-2002.
And yet the risk is not just that asset prices can go swiftly
into reverse. As with traditional inflation, surging asset prices also
distort price signals and so can cause a misallocation of resources-encouraging
too little saving, for example, or too much investment in housing. Surging house
prices may therefore argue for higher interest rates than conventional inflation
would demand. In other words, strict inflation targeting-the fad of the 1990s-is
too crude. |
According to the text, it is upsetting that the Federal Reserve does not take into account inflation targets ______.
A:until what to do is clarified B:until explicit inflation targets are declared C:until increases in asset prices are curbed D:until its efficiency is cast doubt on
