Japanese Lost Decade

Overview

The ‘Lost Decade’ refers to a period of economic stagnation in Japan that began in the 1990s and extended through the 2000s. The asset bubble prices burst in the early 1990s caused a significant loss of wealth and resulted in a banking crisis in Japan. Many banks had a large amount of bad loans, leading to the nation’s financial instability.

From 1991 to 2003, the Japanese economy, as measured by GDP, grew only 1.14% annually, much lower than previous decades. Meanwhile, the country experienced deflation, or falling prices and low labour productivity which further exacerbated economic stagnation. Deflation led to decreased consumer spending and investment, as people and businesses anticipated lower prices in the future.

Despite various monetary and fiscal policy efforts, including lowering interest rates, quantitative easing, and public spending, the economy remained sluggish. Structural reforms were attempted to improve efficiency and address the banking sector’s bad loans, but recovery was slow.

What caused the “Lost Decade” in Japan?

Surplus savings created an asset bubble

Japan’s surplus saving rates have been high since the mid-1970s since the baby boomer generation saved extensively for retirement, driving up the national savings rate. However, even after the baby boomers started retiring, the savings rate did not decline as expected, partly because of the cautious spending behaviour of the aging population.

From a Keynesian economic standpoint, when savings remain unused (either not spent by households or not invested by firms), they lead to a reduction in overall demand of goods consumption and productive investments.

The Japanese government tried to counter this surplus savings by lowering interest rates in the 1980s, making borrowing cheaper to encourage private investment. The surplus savings meant that Japan did not have enough domestic investment opportunities to absorb the capital, leading to speculative investments that were not sustainable.

By the late 1980s, Japan experienced a massive asset bubble driven by excessive speculation in real estate and the stock market. Easy credit and low interest rates fueled these speculative trends,  leading to rapidly rising asset prices.

Bubble Burst

In an attempt to prevent further speculation and keep inflation in check, the Bank of Japan sharply raised interbank lending rates in late 1989. This caused the bursting of the bubble, and the Japanese stock market crashed. Equity and asset prices fell, leaving overly leveraged Japanese banks and insurance companies with books full of bad debt. Many Japanese banks faced financial crisis and were bailed out through capital infusions from the Government of Japan.

Lack of ICT investments

Compared with levels in Europe and the United States, ICT investment in Japan has been surprisingly low since the mid-1990s and was believed as one of the causes of sluggish growth of the country. With the substantial amount of investment in ICT infrastructure, the United States enjoyed steady growth with increased productivity during the 1990s and 2000s.

Another factor of a relative decline in labour productivity in Japan was a reduction in working hours per capita due to the effect of the revision of the Labor Standards Act in 1987, the increases in the number of part-time workers and the insufficient use of older employees by businesses that were not able to respond to the aging of the population.

Economic effects

Despite the mild economic recovery in the 2000s, conspicuous consumption of the 1980s has not returned to the same pre-crash levels. Many Japanese firms have lost their strong competition to rival firms based in South Korea and China.

Moreover, about one-third of Japan’s labour workforce was replaced with temporary workers at that time. Since labour wages have stagnated, household income decreased which caused a strong decline in consumer spending.

In response to chronic deflation and low growth, Japan has attempted economic stimulus and thereby run a fiscal deficit since 1991, turning Japan into the highest level of debt of any nation on earth as of 2013.
