Macroeconomic Effects And Policy Challenges Of Population Aging

This paper simulates the macroeconomic effects of population aging in a dynamic overlapping generations model of a small open economy. The model is calibrated to data for the Czech Republic, where population aging is proceeding at a pace comparable to that in other advanced countries in Europe. Simulations show that population aging is likely to slow economic growth and improvements in living standards. Although reforms to raise labor force participation and productivity growth can mitigate these adverse effects, they are unlikely to eliminate the need for fiscal reforms. The budget will come under pressure from rising age-related expenditures, and consolidation will be needed to preserve debt sustainability.

The United States is in the midst of a major demographic shift. In the coming decades, people aged 65 and over will make up an increasingly large percentage of the population: The ratio of people aged 65+ to people aged 20-64 will rise by 80%. This shift is happening for two reasons: people are living longer, and many couples are choosing to have fewer children and to have those children somewhat later in life. The resulting demographic shift will present the nation with economic challenges, both to absorb the costs and to leverage the benefits of an aging population. Aging and the Macroeconomy: Long-Term Implications of an Older Population presents the fundamental factors driving the aging of the U.S. population, as well as its societal implications and likely long-term macroeconomic effects in a global context. The report finds that, while population aging does not pose an insurmountable challenge to the nation, it is imperative that sensible policies are implemented soon to allow companies and households to respond. It offers four practical approaches for preparing resources to support the future consumption of households and for adapting to the new economic landscape.

'While there already exists a crowded body of publications addressing the effect of an aging population on the economy, this monograph is most outstanding in presenting a global, in-depth analysis of the implications thereby generated for 23 developed and developing countries. . . Scholars, researchers, and practitioners everywhere will benefit immensely from this comprehensive work.' – H.I. Liebling, Choice 'Ron Lee and Andrew Mason's Population Aging and the Generational Economy is a demographic and economic tour-de-force. Their collaborative, intercontinental. . . study of aging, consumption, labor supply, saving, and private and public transfers is the place to go to understand global aging and its myriad and significant economic challenges and opportunities.' – Laurence Kotlikoff, Boston University, US 'The culmination of. . . work by Lee, Mason, and their collaborators from around the world to extend Samuelson's framework to accommodate realistic demography, empirical measurement of age-specific earnings, consumption, tax payments, and benefit receipts, the studies. . . demonstrate the power of this integrated economic-demographic framework to advance our understanding of critical public policy challenges faced by countries at different stages of demographic transition and population aging.' – Robert Willis, University of Michigan, US 'Lee and Mason have done scholars and practitioners a magnificent service by undertaking this comprehensive, compelling, and supremely innovative examination of the economic consequences of changes in population age structure. The book is a bona fide crystal ball. It will be a MUST READ for the next decade!' – David Bloom, Harvard School of Public Health, US 'Population Aging and the Generational Economy provides an encompassing account of what we know about population aging and the impact that this process will have on our economies. It does not confine itself to the advanced industrial countries, where aging has already been largely studied, but adopts a truly global perspective. I am sure it will become a key reference for researchers, students and those involved in policy-making in areas that are affected by population aging.' – Giuliano Bonoli, Swiss Graduate School of Public Administration (IDHEAP), Switzerland Over coming decades, changes in population age structure will have profound implications for the macroeconomy, influencing economic growth, generational equity, human capital, saving and investment, and the sustainability of public and private transfer systems. How the future unfolds will depend on key actors in the generational economy: governments, families, financial institutions, and others. This path-breaking book provides a comprehensive analysis of the macroeconomic effects of changes in population age structure across the globe. The result of a substantial seven-year research project involving over 50 economists and demographers from Africa, Asia, Europe, Latin America, and the United States, the book draws on a new and comprehensive conceptual framework – National Transfer Accounts – to quantify the economic lifecycle and economic flows across generations. It presents comprehensive estimates of both public and private economic flows between generations, and emphasizes the global nature of changes in population age structure that are affecting rich and poor countries alike. This unique and informative book will prove an invaluable reference tool for a wide-ranging audience encompassing students, researchers, and academics in fields such as demography, aging, public finance, economic development, macroeconomics, gerontology, and national income accounting; for policy-makers and advisers focusing on areas of the public sector such as education, health, pensions, other social security programs, tax policy, and public debt; and for policy analysts at international agencies such as the World Bank, the IMF, and the UN.

As the United States and the rest of the world face the unprecedented challenge of aging populations, this volume draws together for the first time state-of-the-art work from the emerging field of the demography of aging. The nine chapters, written by experts from a variety of disciplines, highlight data sources and research approaches, results, and proposed strategies on a topic with major policy implications for labor forces, economic well-being, health care, and the need for social and family supports.

The U.S. population is aging. Social Security projections suggest that between 2013 and 2050, the population aged 65 and over will almost double, from 45 million to 86 million. One key driver of population aging is ongoing increases in life expectancy. Average U.S. life expectancy was 67 years for males and 73 years for females five decades ago; the averages are now 76 and 81, respectively. It has long been the case that better-educated, higher-income people enjoy longer life expectancies than less-educated, lower-income people. The causes include early life conditions, behavioral factors (such as nutrition, exercise, and smoking behaviors), stress, and access to health care services, all of which can vary across education and income. Our major entitlement programs - Medicare, Medicaid, Social Security, and Supplemental Security Income - have come to deliver disproportionately larger lifetime benefits to higher-income people because, on average, they are increasingly collecting those benefits over more years than others. This report studies the impact the growing gap in life expectancy has on the present value of lifetime benefits that people with higher or lower earnings will receive from major entitlement programs. The analysis presented in The Growing Gap in Life Expectancy by Income goes beyond an examination of the existing literature by providing the first comprehensive estimates of how lifetime benefits are affected by the changing distribution of life expectancy. The report also explores, from a lifetime benefit perspective, how the growing gap in longevity affects traditional policy analyses of reforms to the nation's leading entitlement programs. This in-depth analysis of the economic impacts of the longevity gap will inform debate and assist decision makers, economists, and researchers.

The effects of population aging are examined with the aid of a theoretical model and simulations of MULTIMOD. An older population will consume more of aggregate disposable income, require higher government expenditure, and decrease labor supply. These effects should raise real interest rates and lower the capital stock and output. Effects on current balances will depend on the relative speed and extent of aging. Simulations of projected demographic changes suggest that by 2025, real interest rates would be increased by several percentage points and net foreign assets increased in the United States, and decreased in Japan and Germany, as a result.

This book integrates the economics of aging and insight based on political economy and explores generational conflict in the context of governmental spending. This problem is general, as the Covid-19 pandemic has highlighted: lockdowns protect the elderly, but hurt the young. Policies to address global warming impose taxes on the elderly, but would bring benefits largely in the future. This book addresses intergenerational problems by placing its focus on budget allocation, taxation, and regulation. By using Japanese and US data, the authors conduct statistical analysis of whether regions with aging populations may adopt policies that generate benefits during a short period of time instead of policies that could benefit current young generations for an extended period of time. If the policy preferences of voters depend on their age, and if policy adoption by a government reflects public opinion, the change in demographic composition in a region may affect governmental policies. In an aged society, the elderly are pivotal voters. Budgets may be reallocated from policies favored by younger generations, such as education, to policies the elderly prefer, such as welfare programs. This generates an intergenerational externality problem: voters with short life expectancy do not take into consideration long-term benefits. Moreover, the current tax bases may be replaced by other tax bases that do not harm the elderly. The results reported in the book largely support these hypotheses. Evidence also shows that the gender and racial composition and institutional factors, including the extent of fiscal decentralization, are important in anticipating effects of population aging in other countries.

Almost 25 years have passed since the Demography of Aging (1994) was published by the National Research Council. Future Directions for the Demography of Aging is, in many ways, the successor to that original volume. The Division of Behavioral and Social Research at the National Institute on Aging (NIA) asked the National Academies of Sciences, Engineering, and Medicine to produce an authoritative guide to new directions in demography of aging. The papers published in this report were originally presented and discussed at a public workshop held in Washington, D.C., August 17-18, 2017. The workshop discussion made evident that major new advances had been made in the last two decades, but also that new trends and research directions have emerged that call for innovative conceptual, design, and measurement approaches. The report reviews these recent trends and also discusses future directions for research on a range of topics that are central to current research in the demography of aging. Looking back over the past two decades of demography of aging research shows remarkable advances in our understanding of the health and well-being of the older population. Equally exciting is that this report sets the stage for the next two decades of innovative researchâ€"a period of rapid growth in the older American population.
