4 摘要：

本短文考察了关于竞争性储蓄动机及其广泛经济启示的最近文献。竞争性储蓄动机指的是为提高个体在约会和婚恋中选择伴侣时相对于其他竞争者的地位而进行的储蓄。最近文献的主要成果如下：(i) 跨国证据显示，性别比例失衡越大，储蓄率越高；(ii) 家庭层面的证据显示：(a)在性别比例扭曲程度更高的农村地区，有未婚儿子的家庭储蓄率更高，而有未婚女儿的家庭储蓄率与性别失衡没有明显关系；(b)在城市，家庭储蓄率随当地性别比例的升高而升高；(iii)在中国，性别比例升高对房价攀升的贡献率几乎高达一半；(iv) 在性别比例更大的地区，有儿子的家庭更可能成为实业家并从事有风险的工作以赚取更高收入。

Abstract: This short essay surveys recent literature on the competitive saving motive and its broader economic implications. The competitive saving motive is defined as saving to improve one’s status relative to other competitors for dating andmarriage partners. Here are some of the key results of the recent literature:(i) cross-country evidence show that greater gender imbalances tend tocorrespond with higher savings rates; (ii) household-level evidence suggestthat: (a) families with unmarried sons in rural regions with more skewed sex ratios tend to have higher savings rates, while savings rates of families with unmarried daughters appear uncorrelated with gender imbalances; and (b) savings rates of families in cities tend to rise with the local sex ratio; (iii) rising sex ratios contribute nearly half of the rise in housing prices in the People’s Republic of China; and (iv) families with sons in regions of greater sex ratios are more likely to become entrepreneurs and take risky jobs to earn more income.
