This Staff Discussion Note looks at the stark fiscal challenges posed by the decline and aging of populations between now and 2100. It finds that without reforms, pensions and health spending would rise to 25 percent of GDP by end-century in more developed countries (and 16 percent of GDP in less developed countries), with potentially dire fiscal consequences. Given the uncertainty underlying the population projections and associated large fiscal risks, a multi-pronged approach will be required. This could include entitlement reform—starting now but at a gradual pace; policies that affect demographics and labor markets; and better tax systems and more efficient public expenditure.

There is long-standing debate on how population growth affects national economies. A new report from Population Matters examines the history of this debate and synthesizes current research on the topic. The authors, led by Harvard economist David Bloom, conclude that population age structure, more than size or growth per se, affects economic development, and that reducing high fertility can create opportunities for economic growth if the right kinds of educational, health, and labor-market policies are in place. The report also examines specific regions of the world and how their differing policy environments have affected the relationship between population change and economic development.

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.

The Economic and Fiscal Consequences of Immigration finds that the long-term impact of immigration on the wages and employment of native-born workers overall is very small, and that any negative impacts are most likely to be found for prior immigrants or native-born high school dropouts. First-generation immigrants are more costly to governments than are the native-born, but the second generation are among the strongest fiscal and economic contributors in the U.S. This report concludes that immigration has an overall positive impact on long-run economic growth in the U.S. More than 40 million people living in the United States were born in other countries, and almost an equal number have at least one foreign-born parent. Together, the first generation (foreign-born) and second generation (children of the foreign-born) comprise almost one in four Americans. It comes as little surprise, then, that many U.S. residents view immigration as a major policy issue facing the nation. Not only does immigration affect the environment in which everyone lives, learns, and works, but it also interacts with nearly every policy area of concern, from jobs and the economy, education, and health care, to federal, state, and local government budgets. The changing patterns of immigration and the evolving consequences for American society, institutions, and the economy continue to fuel public policy debate that plays out at the national, state, and local levels. The Economic and Fiscal Consequences of Immigration assesses the impact of dynamic immigration processes on economic and fiscal outcomes for the United States, a major destination of world population movements. This report will be a fundamental resource for policy makers and law makers at the federal, state, and local levels but extends to the general public, nongovernmental organizations, the business community, educational institutions, and the research community.

This original and panoramic book proposes that the underlying forces of demography and globalisation will shortly reverse three multi-decade global trends – it will raise inflation and interest rates, but lead to a pullback in inequality. “Whatever the future holds”, the authors argue, “it will be nothing like the past”. Deflationary headwinds over the last three decades have been primarily due to an enormous surge in the world’s available labour supply, owing to very favourable demographic trends and the entry of China and Eastern Europe into the world’s trading system. This book demonstrates how these demographic trends are on the point of reversing sharply, coinciding with a retreat from globalisation. The result? Ageing can be expected to raise inflation and interest rates, bringing a slew of problems for an over-indebted world economy, but is also anticipated to increase the share of labour, so that inequality falls. Covering many social and political factors, as well as those that are more purely macroeconomic, the authors address topics including ageing, dementia, inequality, populism, retirement and debt finance, among others. This book will be of interest and understandable to anyone with an interest on where the world’s economy may be going.

The field of political demography - the politics of population change - is dramatically underrepresented in political science. At a time when demographic changes - aging in the rich world, youth bulges in the developing world, ethnic and religious shifts, migration, and urbanization - are waxing as never before, this neglect is especially glaring and starkly contrasts with the enormous interest coming from policymakers and the media. "Ten years ago, [demography] was hardly on the radar screen," remarks Richard Jackson and Neil Howe of the Center for Strategic and International Studies, two contributors to this volume. "Today," they continue, "it dominates almost any discussion of America's long-term fiscal, economic, or foreign-policy direction." Demography is the most predictable of the social sciences: children born in the last five years will be the new workers, voters, soldiers, and potential insurgents of 2025 and the political elites of the 2050s. Whether in the West or the developing world, political scientists urgently need to understand the tectonics of demography in order to grasp the full context of today's political developments. This book begins to fill the gap from a global and historical perspective and with the hope that scholars and policymakers will take its insights on board to develop enlightened policies for our collective future.

This paper analyses the impact of large and persistent emigration from Eastern European countries over the past 25 years on these countries’ growth and income convergence to advanced Europe. While emigration has likely benefited migrants themselves, the receiving countries and the EU as a whole, its impact on sending countries’ economies has been largely negative. The analysis suggests that labor outflows, particularly of skilled workers, lowered productivity growth, pushed up wages, and slowed growth and income convergence. At the same time, while remittance inflows supported financial deepening, consumption and investment in some countries, they also reduced incentives to work and led to exchange rate appreciations, eroding competiveness. The departure of the young also added to the fiscal pressures of already aging populations in Eastern Europe. The paper concludes with policy recommendations for sending countries to mitigate the negative impact of emigration on their economies, and the EU-wide initiatives that could support these efforts.
