Those in the business of
long-run GDP projections expect Asia, and particularly China, to keep growing
above world trend rates for some years. The most optimistic — such as former
Chief Economist at the World Bank, Justin Lin
— have China growing at 8 per cent for at least the next decade. The
semi-official China 2030
report projects 7 per cent growth later this decade, falling to
between 6–5 per cent by 2030. The Australia in the Asian Century White Paper
projected Chinese economic growth of 7 per cent and Indian growth of
6.75 per cent until 2025.
But ‘the view that the
global economy will increasingly be shaped and lifted by the trajectory of the
giants’ has recently been diagnosed by Larry
Summers and Lant Pritchett as ‘Asiaphoria’. Their careful study
tells us that such ‘abnormally rapid growth is rarely persistent. … Indeed
regression to the mean is the empirically most salient feature of economic
growth’. Emerging countries in particular tend to have super-rapid but
short-lived growth rates, followed by periods of deceleration back to the world
average. They argue rapid growth in China and India ‘will slow substantially, …
Mainly because that is what rapid growth does’.
For the last 30 years around
a quarter of the world’s population has lived in countries with what Summers
and Pritchett call a ‘super-rapid growth rate’ above 6 per cent a year. This
growth has been unusually consistent through time. While Chinese and Indian
growth has been slightly more volatile than that of the US over the period 1980
to 2014, it’s cushioned by a much higher trend. In that period, there were five
years in which US real GDP declined. Despite Tiananmen, the Asian Financial
Crisis and the ‘sharp discontinuities’ of the Global Financial Crisis (GFC) and
the euro crisis, China hasn’t experienced a single negative year in that
period. Nor has India.
So why do two Harvard
professors conclude that the lived experience of the world’s most populous
nations was such a freak event?
Summers and Pritchett use
the example of Denmark to show that a 94 year growth forecast based solely on
long-term trends isn’t far off. But Denmark was already an advanced country in
1910, with a per capita income that was higher than the average for Western
Europe, and three quarters of that of the United States. Ninety four years
later it reached 80 per cent of US income levels. That it was already
a small, rich country in 1910 makes it a red herring for drawing inferences for
the Asian giants.
Time series regressions miss
structural breaks. This certainly happened when Chinese institutions moved
decisively towards a market economy on a continental scale from the late-1970s.
India began to (partially) liberalise in the 1990s.
China’s was no simple
Thatcher or Reagan-style deregulation. The Chinese rediscovered private
property rights, reinvented private enterprise and re-opened to foreign trade
for the purpose of catching up to modern science and technology. Using a simple
mean reversion forecasting technique back in the 1970s would have completely
missed this. And it misses the potential for continued — albeit slower —
catch-up growth today.
It’s easy for modern
visitors to forget just how poor China was. According to Angus Maddison’s historical GDP estimates,
per capita GDP of the United States in 1820 was higher than China’s in 1978.
Thirty years later, per capita income in China has caught up to where the US
was just before the Great Depression. Based on the quality of its current
institutions, China could converge to two-thirds of US productivity levels —
richer, but still three decades behind the US frontier. Visitors on the maglev
to Shanghai may not see this, but those on the overnight bus to rural Anhui
realise there’s still a long way to go.
The long-term trend isn’t a
guarantee against policy missteps or market shocks. Like the US before the
Great Depression, China faces large economic and financial risks. Summers and
Pritchett give us a timely reminder of these. In particular, how the politics
of an economic shock might play out is the biggest wildcard in forecasting
China’s growth. But on fundamentals, long-run Chinese growth won’t
settle at 2–3 per cent any time soon.
The Chinese leadership
takes history seriously in a way that is difficult to conceive for younger
countries like Australia or the United States. The last century was the first
time that United States has been a superpower. For China, not being a
superpower is the historical irregularity.
In fact, the rise of Asia
might be better conceived as the re-emergence of a world in which population
size and economic size are closely linked. First in Europe, then in North
America, new technology and forms of energy severed this link, leading to
radical inequality in the wealth of nations. So today, the United States
produces 16 per cent of world output with just 4 per cent
of world population.
The global diffusion of
technology, and institutions, has given poor but populous countries an
opportunity to catch up. China also produces 16 per cent of world
output, but with 20 per cent of world population. Expecting this to
be its natural resting place — the consequence of everyone growing at global
trend — might be a symptom of Asiaphobia.
