World to pay as China’s boom ends

By Paul Krugman

All economic data are best viewed as a peculiarly boring genre of science fiction, but Chinese data are more fictional than most. Add a secretive government, a controlled press and the sheer size of the country, and it is harder to figure out what is really happening in China than it is in any other major economy.

Yet the signs are now unmistakable: China is in big trouble. We are not talking about some minor setback along the way, but something more fundamental. The country’s whole way of doing business — the economic system that has driven three decades of incredible growth — has reached its limits. You could say that the Chinese model is about to hit its Great Wall and the only question now is just how bad the crash will be.

Start with the data, unreliable as they may be. What immediately jumps out when one compares China with almost any other economy, aside from its rapid growth, is the lopsided balance between consumption and investment.

All successful economies devote part of their current income to investment rather than consumption, so as to expand their future ability to consume. However, China seems to invest only to expand its future ability to invest even more. The US, admittedly on the high side, devotes 70 percent of its GDP to consumption. For China, the number is only half that, while almost half of GDP is invested.

How is that even possible? What keeps consumption so low and how have the Chinese been able to invest so much without — until now — running into sharply diminishing returns?

The answers are the subject of intense controversy. However, the story that makes the most sense to me rests on an old insight by economist W. Arthur Lewis, who argued that countries in the early stages of economic development typically have a small modern sector alongside a large traditional sector containing huge amounts of “surplus labor”: underemployed peasants making at best a marginal contribution to overall economic output.

The existence of this surplus labor, in turn, has two effects.

First, for a while such countries can invest heavily in new factories, construction and so on without running into diminishing returns, because they can keep drawing in new labor from the countryside. Second, competition from this reserve army of surplus labor keeps wages low even as the economy grows richer.

The main thing holding down Chinese consumption seems to be that Chinese families never see much of the income being generated by the country’s economic growth. Some of that income flows to a politically connected elite, but much of it simply stays bottled up in businesses, many of them state-owned enterprises.

It is all very peculiar by Western standards, but it worked for several decades. However, now China has hit the “Lewis point,” which, to put it crudely, means it is running out of surplus peasants.

That should be a good thing. Wages are rising and finally, ordinary Chinese are starting to share in the fruits of growth.

Yet it also means that the Chinese economy is suddenly faced with the need for drastic “rebalancing” — the jargon phrase of the moment. Investment is now running into sharply diminishing returns and is going to drop drastically no matter what the government does and consumer spending must rise dramatically to take its place. The question is whether this can happen fast enough to avoid a nasty slump.
