"This is the thirteenth in a series of NBER volumes on the Economics of Aging"--Introduction.

We explore two issues triggered by the crisis. First, in most advanced countries, output remains far below the pre-recession trend, suggesting hysteresis. Second, while inflation has decreased, it has decreased less than anticipated, suggesting a breakdown of the relation between inflation and activity. To examine the first, we look at 122 recessions over the past 50 years in 23 countries. We find that a high proportion of them have been followed by lower output or even lower growth. To examine the second, we estimate a Phillips curve relation over the past 50 years for 20 countries. We find that the effect of unemployment on inflation, for given expected inflation, decreased until the early 1990s, but has remained roughly stable since then. We draw implications of our findings for monetary policy.

The Economics of Aging presents results from an ongoing National Bureau of Economic Research project. Contributors consider the housing mobility and living arrangements of the elderly, their labor force participation and retirement, the economics of their health care, and their financial status. The goal of the research is to further our understanding both of the factors that determine the well-being of the elderly and of the consequences that follow from an increasingly older population with longer individual life spans. Each paper is accompanied by critical commentary.

Oldness: a social construct at odds with reality that constrains how we live after middle age and stifles business thinking on how to best serve a group of consumers, workers, and innovators that is growing larger and wealthier with every passing day. Over the past two decades, Joseph F. Coughlin has been busting myths about aging with groundbreaking multidisciplinary research into what older people actually want -- not what conventional wisdom suggests they need. In The Longevity Economy, Coughlin provides the framing and insight business leaders need to serve the growing older market: a vast, diverse group of consumers representing every possible level of health and wealth, worth about $8 trillion in the United States alone and climbing. Coughlin provides deep insight into a population that consistently defies expectations: people who, through their continued personal and professional ambition, desire for experience, and quest for self-actualization, are building a striking, unheralded vision of longer life that very few in business fully understand. His focus on women -- they outnumber men, control household spending and finances, and are leading the charge toward tomorrow's creative new narrative of later life -- is especially illuminating. Coughlin pinpoints the gap between myth and reality and then shows businesses how to bridge it. As the demographics of global aging transform and accelerate, it is now critical to build a new understanding of the shifting physiological, cognitive, social, family, and psychological realities of the longevity economy.

This year, the NBER Macroeconomics Annual celebrates its thirtieth volume. The first two papers examine China’s macroeconomic development. “Trends and Cycles in China's Macroeconomy” by Chun Chang, Kaiji Chen, Daniel F. Waggoner, and Tao Zha outlines the key characteristics of growth and business cycles in China. “Demystifying the Chinese Housing Boom” by Hanming Fang, Quanlin Gu, Wei Xiong, and Li-An Zhou constructs a new house price index, showing that Chinese house prices have grown by ten percent per year over the past decade. The third paper, “External and Public Debt Crises” by Cristina Arellano, Andrew Atkeson, and Mark Wright, asks why there appear to be large differences across countries and subnational jurisdictions in the effect of rising public debts on economic outcomes. The fourth, “Networks and the Macroeconomy: An Empirical Exploration” by Daron Acemoglu, Ufuk Akcigit, and William Kerr, explains how the network structure of the US economy propagates the effect of gross output productivity shocks across upstream and downstream sectors. The fifth and sixth papers investigate the usefulness of surveys of household’s beliefs for understanding economic phenomena. “Expectations and Investment,” by Nicola Gennaioli, Yueran Ma, and Andrei Shleifer, demonstrates that a chief financial officer's expectations of a firm's future earnings growth is related to both the planned and actual future investment of that firm. “Declining Desire to Work and Downward Trends in Unemployment and Participation” by Regis Barnichon and Andrew Figura shows that an increasing number of prime-age Americans who are not in the labor force report no desire to work and that this decline accelerated during the second half of the 1990s.

Aging and Social Policy in the United States guides students through an exploration of social policies and policymaking that address the needs of older adults and their families. It situates the experiences of older adults in the context of their environment, examining social welfare policies that affect the rights and interests of older adults. The book begins with an introductory unit, providing a foundation for the book, defining key terms, describing how to analyze the impacts of a policy on a population, and examining the ways in which policy is positioned within societal assumptions. Utilizing the life course perspective, the middle three units of this book situate individual biological and psychological challenges of aging in the context of how they are addressed by individuals, families, and societies, identifying the strengths and challenges of existing and proposed social policies at each of these levels. The concluding unit provides comparative insights as to how aging issues are addressed in a sample of countries around the world. Aging and Social Policy in the United States provides undergraduate and graduate students with critical knowledge and perspectives on the complexities of addressing the needs of an aging population.

What circumstances or behaviors turn poverty into a cycle that perpetuates across generations? The answer to this question carries especially important implications for the design and evaluation of policies and projects intended to reduce poverty. Yet a major challenge analysts and policymakers face in understanding poverty traps is the sheer number of mechanisms—not just financial, but also environmental, physical, and psychological—that may contribute to the persistence of poverty all over the world. The research in this volume explores the hypothesis that poverty is self-reinforcing because the equilibrium behaviors of the poor perpetuate low standards of living. Contributions explore the dynamic, complex processes by which households accumulate assets and increase their productivity and earnings potential, as well as the conditions under which some individuals, groups, and economies struggle to escape poverty. Investigating the full range of phenomena that combine to generate poverty traps—gleaned from behavioral, health, and resource economics as well as the sociology, psychology, and environmental literatures—chapters in this volume also present new evidence that highlights both the insights and the limits of a poverty trap lens. The framework introduced in this volume provides a robust platform for studying well-being dynamics in developing economies.

Health in later life is shaped by behavior and policies over the life course and reflects the differences between the societies in which we are ageing. This multidisciplinary book answers questions from all life course phases and its interconnections from a European perspective based on the most recent SHARE data, such as: How is our health related to personality traits and influenced by our childhood conditions and careers? Which role does our social network play? Which impacts of the different health care and societal regimes can we trace at older ages? Which are the differences and similarities across European countries?

In recent years, the retirement age for public pensions has increased across many countries, and additional increases are in progress or under discussion in many more. The seventh stage of an ongoing research project studying the relationship between social security programs and labor force participation, Social Security Programs and Retirement around the World: The Capacity to Work at Older Ages explores people’s capacity to work beyond the current retirement age. It brings together an international team of scholars from twelve countries—Belgium, Canada, Denmark, France, Germany, Italy, Japan, the Netherlands, Spain, Sweden, the United Kingdom, and the United States—to analyze this issue. Contributors find that many—but not all—individuals have substantial capacity to work at older ages. However, they also consider how policymakers might divide gains in life expectancy between years of work and retirement, as well as the main impediments to longer work life. They consider factors that influence the demand for older workers, as well as the evolution of health and disability status, which may affect labor supply from the older population.

'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.
