중국의 높은 저축율은 남녀 성비 불균형 때문?

높은 저축율의 원인에 대한 이색적인 접근. 1980년대에 시작된 남녀 성비 불균형으로 결혼자금을 위해 저축율이 높아졌다고 하는데, 이건 정말 인과관계가 있는 걸까 아님 그냥 상관관계만 있는 걸까.

Competition for Brides Fuels High China Savings

By Brenda Cronin

One prescription for addressing China’s trade imbalance with the U.S. is to persuade the country’s tiger moms to loosen their purse strings.
Shang-Jin Wei, director of the Chazen Institute and a professor at Columbia Business School, said Wednesday that China’s demographic situation — 1.15 pre-marital-age men for every one woman — is the fundamental factor behind the nation’s high savings rate.
That’s because “desperate parents” are using education and wealth to make their sons stand out as catches in an increasingly competitive marriage market, Professor Wei said.
