Average Annual GDP in Japan 1980-2009

A quick post on Japan. Japan had what many called a “lost decade” from about 1992 to 2003. The trouble is that there is debate about when the lost decade ended and to what extent this lost decade showed up in average GDP figures. It seems that positive credit growth did not return until 2006, when deleveraging in Japan’s private sector ended (especially by corporations).

Here is the data:
Japanese Annualised Average GDP, 1980-2009
Year | GDP

1980 | 2.82%
1981 | 2.93%
1982 | 2.76%
1983 | 1.61%
1984 | 3.12%
1985 | 5.08%
1986 | 2.96%
1987 | 3.79%
1988 | 6.76%
1989 | 5.29%
1990 | 5.20%
1991 | 3.32%
1992 | 0.82%
1993 | 0.17%
1994 | 0.86%
1995 | 1.88%
1996 | 2.64%
1997 | 1.56%
1998 | -2.05%
1999 | -0.14%
2000 | 2.86%
2001 | 0.18%
2002 | 0.26%
2003 | 1.41%
2004 | 2.74%
2005 | 1.93%
2006 | 2.04%
2007 | 2.36%
2008 | -1.17%
2009 | -6.29%
2010 | 4.00%

Average GDP growth rate, 1981–1990: 3.95%
Average GDP growth rate, 1991–2000: 1.19%
Average GDP growth rate, 2001–2010: 0.75%
Average GDP growth rate, 1992–2003: 0.87%

http://wikiposit.org/am?WB.JPN.NY.GDP.MKTP.KD.ZG=101
The average of just 1.19% for 1991–2000 (down from 3.95% from 1981–1990) suggests something did indeed go wrong with the economy in the 1990s. The average for the whole period 1992–2003 was 0.87%.

But the average for 2001-2010 is just 0.75%, which is surprising. However, a careful look at the data shows the average was brought down by the extremely bad GDP contraction of 2009, owing to the global recession and slump in demand for Japan’s exports. Without it, average GDP for the decade from 2001-2010 would be 1.53%. If we remove the disaster of the global recession of 2008-2009, then Japan’s average GDP from 2001-2007 was 1.56%.

The GDP data for the period 2003 to 2007 (before the crisis hit) show an average of 2.10%, and suggest that Japan’s economy had returned to roughly the OECD average in these years. This confirms that Japan had come out of the lost decade after 2003.

  2. Why don't you want to understand it ? Why ? How many times should I repeat it for you ? Please, answer me.

    "From 1980-2009 (as far as this data set goes, unfortunately) Japanese GDP/capita has kept pace with the US. In fact, growth has actually exceeded that of the US over the whole period (US GDP per capita is still higher on an absolute basis though). This indicates that productivity has kept pace with the US even if aggregate GDP has not. Importantly, rising per capita GDP means that standards of living have risen, not fallen, which is the primary reason for economic activity: higher standards of living."

    1. (1) per capita GDP isn't the only metric: real GDP is just as important.

      (2) the data shows an average GDP growth rate from 1992–2003 of 0.87%: quite low.

      (3) I wonder whether the real per capita GDP figures are related to the population decline in Japan since 2005 that some sources report (though disputed):

      http://www.bbc.co.uk/news/business-17751783

      The growth rate of Japan's population must also have slowed before the actual population contraction some report, another factor influencing per capita GDP figures.

      (4) furthermore, if they taken steps to stop the lost decade from happening back in 1993/04, then per capita GD would have been even higher now than the figures you report.

    "Despite outpacing the US between 1980 and 1990, Japanese GDP has nearly flat-lined since. Most people know that a large part of the problem is demographic. The Japanese working-age population has similarly flat-lined over the same period, and the total population has actually begun to shrink."

    See also Daniel Gros.

    "How should one compare growth records among a group of similar developed countries? The best measure is not overall GDP growth, but the growth of income per head of the working-age population (not per capita). This last element is important because only the working-age population represents an economy’s productive potential. If two countries achieve the same growth in average WAP income, one should conclude that both have been equally efficient in using their potential, even if their overall GDP growth rates differ.

    When one looks at GDP compared with WAP figures (defined as the population aged 20 to 60), one gets a surprising result: Japan has actually done better than the US or most European countries over the last decade. The reason is simple: Japan’s overall growth rates have been quite low, but growth was achieved despite a rapidly shrinking working-age population."

    "While GDP growth has been weak, its productivity growth has been better than the average in the OECD."

  4. Isn't this the gist of what I just said?

    Demographic factors lie behind the per capita GDP figures.

    The actual real GDP data show very low growth 1992-2003, which reflects the economic malaise in these view, especially the deep recession 1999-1999 (which was the result of austerity).
