By the beginning of the 1980s, double-digit rates of inflation had become so pervasive among industrialized economies that they were viewed as a major deterrent to global economic growth. Since then, an explicit policy goal of low inflation has become a mantra for policymakers, and many countries, such as the U.K., New Zealand, Australia, Japan, Sweden, and the eleven countries under the European Central Bank (ECB), have enacted fundamental reforms to achieve that goal. Specifically, they have made their central banks more independent and thus insulated them from the temptations of inflationary finance; furthermore, in most of these cases, as well as in the U.S., central banks have practiced a greater degree of openness or transparency about monetary policy decisionmaking to give the private sector a better opportunity to monitor their activities.
Today, these countries can claim considerable success in reducing both inflation and inflationary expectations. For example, despite the run-up in energy prices in 2000, consumer price inflation rates from 1999.Q3 through 2000.Q3 fell to 3.5% in the U.S., to 3.2% in the U.K., to 1.6% in the EMU countries, to 2.7% in Canada, to 0.9% in Sweden, and to 3.0% in New Zealand. Japan, with an inflation rate of -1.2%, is something of a special case, as it is just beginning to emerge from a prolonged recession.
With inflation rates now in the low single digits, attention has become more narrowly focused on the problem of determining quantitatively what the "optimal" inflation rate should be. Evidence to date suggests that policymakers?iews have coalesced, however tentatively, around a "2% solution" to this question. For example, consider these explicit inflation targets: 2.5% for the Bank of England, less than 2% for the ...
