在大多数发展中国家,年轻人占总人口的比例要大于多数发达国家。但是,发达国家的储蓄率却往往高于欠发达国家的储蓄率。试讨论这种情况如何与年轻人倾向于比老年人多储蓄的假说相统一。 In most developing countries.the share 0f young people in the total population is larger than in most developed countries.However.developed countries tend to have higher saving rates than do less developed ones.Discuss how this observation may be reconciled with the hypothesis that the young tend to save more than the old.
