This paper considers the implications of the prospective aging of the U.S. population for the social security system and concludes that the large and growing cashflow surpluses of the social security trust funds should be saved to help insulate living stands against this change. A number of...

The macroeconomic effects of population aging are explored using data for the G-7 countries and Australia. The link between changes in birth and mortality rates on the one hand, and dependency ratios on the other, is first discussed, then empirical evidence on the effects of dependency ratios on...

Significant aging is projected for many high-saving emerging economies of East and Southeast Asia. By 2025, the share of the elderly in their populations will at least double in most of these countries. The share of the young will fall. Aging populations could adversely affect saving rates in...

The paper assesses the government expenditure effects from changing demographics in the Asian “Tiger” economies through 2050. With some exceptions, their limited social insurance commitments initially suggest that aging populations may not adversely affect fiscal balances. Yet for all the...

Africa will account for 80 percent of the projected 4 billion increase in the global population by 2100. The accompanying increase in its working age population creates a window of opportunity, which if properly harnessed, can translate into higher growth and yield a demographic dividend. We...

The ongoing demographic changes will bring about a substantial shift in the size and the age composition of the population, which will have significant impact on the global economy. Despite potentially grave consequences, demographic changes usually do not take center stage in many macroeconomic...

In coming decades, China will undergo a notable demographic transformation, with its old-age dependency ratio doubling to 24 percent by 2030 and rising even more precipitously thereafter. This paper uses the permanent income hypothesis to reassess national savings behavior, with greater...

This paper examines the effects of demographic dynamics on the measured rates of economic growth. First, it develops a model of production with labor productivity that varies with age. Second, it uses macroeconomic and demographic data to estimate the relative productivity of different age...

This paper investigates the long-run pattern of private saving in Indonesia, Malaysia, Singapore, and Thailand. These countries have not only maintained saving levels that are currently among the highest in the world but have also experienced a sustained increase in their rate of private saving...
