1. Introduction
The
Japanese economy has been underperforming for more than a decade. The average
growth rate of real GDP over the past 12 years has been just above 1 percent,
and the nominal GDP has been shrinking since 1997 due to deflation. In order to
stimulate the stagnant economy, the government has cut taxes and increased expenditures.
As a result the government debt/GDP ratio has risen to an unprecedented level
for an advanced country in peacetime. The CPI has been declining since 1998, while
the GDP deflator has been declining since 1995. Stock prices and land prices
have been declining for the decade. There is no doubt that the economy is in
deflation. The consumption tax rate increase and repeal of income tax cut in
April 1997 is often regarded as a fiscal policy mistake. Slow structural reform
in regulated sectors is another problem for the Japanese economy. The most
likely cause for deflation in Japan is a failure of monetary policy, since
inflation or deflation is ultimately a monetary phenomenon. The Bank of Japan
(BOJ) was unable to stop the inflation rate from turning negative, despite its
various efforts. The Bank of Japan’s actions were too little too late, at least
in retrospect, in preventing deflation from emerging and fighting out of
deflation.
