Super-Economy: Japan's problem is supply, not demand (updated)

Super-Economy: Japan's problem is supply, not demand (updated)
...Let's first look at the lost decade, 1991-2000. When the rest of the world was having rapid, IT-fueled growth, Japan was stagnating. Here are the growth rates in real GDP between 1991-2000:

For all the nice years Japan had 9.6% growth compared to 38.7% for the U.S and 22.7% for the EU.15. The U.S grew by an average of 3.7% per year, Japan only 1.0% per year.

But as most of you know Japan is undergoing a rapid demographic transition. The country was and is aging. Because the old and children cannot work, when we want to compare countries with very different demographic characteristics instead of calculating GDP per capita, it makes sense to calculate GDP per working age adult (people aged 15-65).

Whereas the number of potential workers in the U.S increased by 13% during Japans "lost decade" (1991-2000), and by 3% in for example France, the Japanese potential workforce actually shrank during these years. Adjusting for this, the growth in Japan was 9.8%, compared to 16.9% in Germany, 17.3% in France, 16.3% in Italy and 23.2% in the United States. The U.S grew by twice, not four times of Japan (remember that these were the best years of the U.S and the worst years of Japan).

The importance of the demographic transformation in Japan is even more clear if we include the entire 1990-2007 period.

In non-population adjusted figures, Japan's real GDP grew by 26% in total these years, the lowest in the OECD. In comparison the figures are 63% for the U.S and 44% for the EU.15.

But during this period the U.S saw it's potential labor force (the number of people between 15-65) increase by 23% and the EU.15 by 11%, while Japan had a decrease of 4%.

Between 1990-2007, GDP per working age adult increased by 31.8% in the United States, by 29.6% in EU.15 and by 31.0% in Japan. The figures are nearly identical!

Japan has simply not been growing slower than other advanced countries once we adjust for demographic change.


Also notice Italy (who does better than we think) and Ireland (who does worse, much of the growth was due to their young population).

Nor did productivity grow any slower in Japan than Europe.

The Triumph of the Stupidly Optimistic

The Triumph of the Stupidly Optimistic
How many jobs are there where being wrongly optimistic for ages gets you promoted? I offer you ... equity analysts, who have, on average, overestimated S&P 500 earnings by 2x for a generation.

I’d add another point: the 19th-century economy had much more flexible prices and wages than later came to be the case — not, primarily, because of different institutions, but because it was still largely an economy of small, self-employed farmers. More than half of US workers were in agriculture up until the 1880s. Peter Temin has told me — I can’t find it in a quick search — that the United States didn’t start having modern recessions, with large declines in real GDP, until the Panic of 1873; Britain started having them much earlier, because it became an industrial economy earlier.
