China’s one-child policy not only intruded into the personal lives of Chinese couples, but it may also have been a key contributor to the economic bubble:
Could a reproductive policy have caused the financial crisis? Could it still be wreaking havoc with the world economy? During a lively discussion at the Council on Foreign Relations yesterday, Columbia professor Shang-Jin Wei said this could be the case. He claimed that the skewed Chinese sex ratio (there are more men than women) can explain much of global trade imbalances. Mr Wei reckons the Chinese sex ratio can explain the high Chinese saving rate, and this is what’s behind China’s current-account surplus.
China adopted the one child law in the early 1980s. It resulted in a skewed sex ratio because many couples preferred a male baby and aborted female fetuses. In 1980, 106 boys were born were born for every 100 girls. By 1997, it was 122 boys for every 100 girls. This means that today one in nine Chinese men will probably never marry and the situation is expected to get worse as time goes on. It’s been suggested that the large pool of single men with no marriage prospects can lead to social unrest. What that will mean for China’s political future is uncertain and potentially troubling. But the world may already be experiencing the economic impact of this policy. Trade imbalances, specifically the Chinese current account surplus and America’s current account deficit, are often cited as a cause of the financial crisis. They provided a glut of cheap, easy capital which fed the housing bubble.

The lack of a social safety net is often blamed for the high Chinese saving rate. Without welfare and government pensions the Chinese must save to self-insure themselves. But Mr Wei pointed out that even as the government has extended more social welfare programmes, the saving rate has continued to rise. He believes the uneven sex ratio can explain half of the increase in private saving between 1990 and 2005. He explained that the marriage market is becoming very competitive with so few girls. Chinese parents want to accumulate as much wealth as possible to ensure that their son can attract a wife. It is also important to provide sons with the best education possible. A competitive marriage market means that members of the disadvantaged gender must raise their game, which in China means greater wealth and education.
Mr Wei also reckons the sex ratio can explain capital accumulation in the corporate sector. The desire to accumulate wealth means that boys and their parents are more likely to become entrepreneurs, work more hours and take more unpleasant jobs. He found higher rates of entrepreneurship in areas with more skewed sex ratios.
This, of course, is the optimistic view of things. The pessimistic view involves those tens of millions of men who can never find wives and projects that into social unrest, civil disorder, and military adventurism. Let’s hope the optimistic view is closer to being correct.
