Why the Chinese Save

Some say that a major cause of the U.S. housing bubble was a surge in savings overseas, particularly in China, where the personal savings rate soared to 30 percent of disposable income. (In the U.S., meanwhile, we were saving next to nothing). Just why the Chinese were saving so much has been a puzzle to many economists. Now Shang-Jin Wei and Xiaobo Zhang think they’ve come up with an explanation. It turns out that China’s “one child” policy, which created a huge surplus of men in the country, has driven up the cost of getting married, as more and more men compete for fewer and fewer women. To keep up, families with sons have been holding off on spending to save up wealth that boosts their children’s marriage prospects. In their paper, Wei and Zhang argue that Chinese marriage-price inflation could account for as much as half of the increase in the country’s household savings since 1990. [%comments]
