Climate and demographic changes are two major long-term trends that are evolving simultaneously. The global population is aging, while climate change is increasing the frequency and severity of weather-related disasters and lowering productivity. This paper examines the macroeconomic effects of these three changes in a common framework. Simulation results suggest that while aging drags down the real interest rate, climate change puts upward pressure on the real interest rate and inflation. As climate change intensifies, it will be the dominant factor shaping the macroeconomic variables. This results in higher inflation and a higher debt-to-GDP ratio, requiring tighter fiscal and monetary policies. The results further suggest that economic uncertainty induced by climate change amplifies these effects of climate change.

We study the long-term impact of climate change on economic activity across countries, using a stochastic growth model where labor productivity is affected by country-specific climate variables—defined as deviations of temperature and precipitation from their historical norms. Using a panel data set of 174 countries over the years 1960 to 2014, we find that per-capita real output growth is adversely affected by persistent changes in the temperature above or below its historical norm, but we do not obtain any statistically significant effects for changes in precipitation. Our counterfactual analysis suggests that a persistent increase in average global temperature by 0.04°C per year, in the absence of mitigation policies, reduces world real GDP per capita by more than 7 percent by 2100. On the other hand, abiding by the Paris Agreement, thereby limiting the temperature increase to 0.01°C per annum, reduces the loss substantially to about 1 percent. These effects vary significantly across countries depending on the pace of temperature increases and variability of climate conditions. We also provide supplementary evidence using data on a sample of 48 U.S. states between 1963 and 2016, and show that climate change has a long-lasting adverse impact on real output in various states and economic sectors, and on labor productivity and employment.

'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.

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.

Ending poverty and stabilizing climate change will be two unprecedented global achievements and two major steps toward sustainable development. But the two objectives cannot be considered in isolation: they need to be jointly tackled through an integrated strategy. This report brings together those two objectives and explores how they can more easily be achieved if considered together. It examines the potential impact of climate change and climate policies on poverty reduction. It also provides guidance on how to create a “win-win†? situation so that climate change policies contribute to poverty reduction and poverty-reduction policies contribute to climate change mitigation and resilience building. The key finding of the report is that climate change represents a significant obstacle to the sustained eradication of poverty, but future impacts on poverty are determined by policy choices: rapid, inclusive, and climate-informed development can prevent most short-term impacts whereas immediate pro-poor, emissions-reduction policies can drastically limit long-term ones.

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 first World Climate Conference, which was sponsored by the World Meteorological Organization in Gen?ve in 1979, triggered an international dialogue on global warming. From the 1997 United Nations-sponsored conference-during which the Kyoto Protocol was signed-through meetings in Copenhagen, Canc?n, Durban, and most recently Doha (2012) and Warsaw (2013), worldwide attention to the issue of global warming and its impact on the world's economy has rapidly increased in intensity. The consensus of these debates and discussions, however, is less than clear. Optimistically, many geoscience researchers and members of the Intergovernmental Panel on Climate Change (IPCC) have supported CO2 emission reduction pledges while maintaining that a 2?C limit in increased temperature by the year 2100 is achievable through international coordination. Other observers postulate that established CO2 reduction commitments such as those agreed to at the Copenhagen United Nations Climate Change Conference (2009) are insufficient and cannot hold the global warming increase below 2?C. As experts theorize on precisely what impact global warming will have, developing nations have become particularly alarmed. The developed world will use energy to mitigate global warming effects, but developing countries are more exposed by geography and poverty to the most dangerous consequences of a global temperature rise and lack the economic means to adapt. The complex dynamics that result from this confluence of science and geopolitics gives rise to even more complicated issues for economists, financial planners, business leaders, and policy-makers. The Oxford Handbook of the Macroeconomics of Global Warming analyzes the economic impact of issues related to and resulting from global warming, specifically the implications of possible preventative measures, various policy changes, and adaptation efforts as well as the different consequences climate change will have on both developing and developed nations. This multi-disciplinary approach, which touches on issues of growth, employment, and development, elucidates for readers state-of-the-art research on the complex and far-reaching problem of global warming.

The year 2008 marks the beginning of the baby boomer retirement avalanche just as the different demographics in advanced and most developing countries are becoming more pronounced. People are worrying again that developments in global population trends, food supply, natural resource availability and climate change raise the question as to whether Malthus was right after all. The Age of Aging explores a unique phenomenon for mankind and, therefore, one that takes us into uncharted territory. Low birth rates and rising life expectancy are leading to rapid aging and a stagnation or fall in the number of people of working age in Western societies. Japan is in pole position but will be joined soon by other Western countries, and some emerging markets including China. The book examines the economic effects of aging, the main proposals for addressing the implications, and how aging societies will affect family and social structures, and the type of environment in which the baby-boomers' children will grow up. The contrast between the expected old age bulge in Western nations and the youth bulge in developing countries has important implications for globalization, and for immigration in Western countries - two topics already characterized by rising discontent or opposition. But we have to find ways of making both globalization and immigration work for all, for fear that failure may lead us down much darker paths. Aging also brings new challenges for the world to address in two sensitive areas, the politicization of religion and the management of international security. Governments and global institutions will have to take greater responsibilities to ensure that public policy responses are appropriate and measured. The challenges arising within aging societies, and the demographic contrasts between Western and developing countries make for a fractious world - one that is line with the much-debated 'decline of the West'. The book doesn't flinch from recognizing the ways in which this could become more visible, but also asserts that we can address demographic change effectively if governments and strengthened international institutions are permitted a larger role in managing change.

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.
