Population Matters


Book Description

The effect of demography on economic performance has been the subject of intense debate in economics for nearly two centuries. In recent years opinion has swung between the Malthusian views of Coale and Hoover, and the cornucopian views of Julian Simon. Unfortunately, until recently, data were too weak and analytical models too limited to provide clear insights into the relationship. As a result, economists as a group have not been clear or conclusive. This volume, which is based on a collection of papers that heavily rely on data from the 1980s and 1990s and on new analytical approaches, sheds important new light on demographic—economic relationships, and it provides clearer policy conclusions than any recent work on the subject. In particular, evidence from developing countries throughout the world shows a pattern in recent decades that was not evident earlier: countries with higher rates of population growth have tended to see less economic growth. An analysis of the role of demography in the "Asian economic miracle" strongly suggests that changes in age structures resulting from declining fertility create a one-time "demographic gift" or window of opportunity, when the working age population has relatively few dependants, of either young or old age, to support. Countries which recognize and seize on this opportunity can, as the Asian tigers did, realize healthy bursts in economic output. But such results are by no means assured: only for countries with otherwise sound economic policies will the window of opportunity yield such dramatic results. Finally, several of the studies demonstrate the likelihood of a causal relationship between high fertility and poverty. While the direction of causality is not always clear and very likely is reciprocal (poverty contributes to high fertility and high fertility reinforces poverty), the studies support the view that lower fertility at the country level helps create a path out of poverty for many families. Population Matters represents an important further step in our understanding of the contribution of population change to economic performance. As such, it will be a useful volume for policymakers both in developing countries and in international development agencies.




The Global Impact of Demographic Change


Book Description

The world is in the midst of a major demographic transition. This paper examines the implications of such transition over the next 80 years for Japan, the United States, other industrial countries, and the developing regions of the world using a dynamic intertemporal general equilibrium four-country model containing demographics calibrated to the "medium variant" of the United Nations population projections. We find that population aging in industrial countries will reduce aggregate growth in these regions over time, but should boost growth in developing countries over the next 20-30 years, as the relative size of their workingage populations increases. Demographic change will also affect saving, investment, and capital flows, implying changes in global trade balances and asset prices. We also explore the sensitivity of the results to assumptions about future productivity growth and country external risk for the developing country region.




Effects of Long-Run Demographic Changes in a Multi-Country Model


Book Description

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 net foreign asset positions and on consumption is presented. Simulations of changes in dependency ratios are then reported, using demographic projections to the year 2025. Finally, the plausibility of the implied changes in net foreign asset positions is discussed.




The Effects of Interest Reates on Savings in Developing Countries


Book Description

Time -series estimates for individual countries and cross -section and time -series estimates for a number of countries show the positive effects of interest rates on savings.







On the Contribution of Demographic Change to Aggregate Poverty Measures for the Developing World


Book Description

Recent literature and new data help determine plausible bounds to some key demographic differences between the poor and non-poor in the developing world. The author estimates that selective mortality-whereby poorer people tend to have higher death rates-accounts for 10-30 percent of the developing world's trend rate of "$1 a day" poverty reduction in the 1990s. However, in a neighborhood of plausible estimates, differential fertility-whereby poorer people tend also to have higher birth rates-has had a more than offsetting poverty-increasing effect. The net impact of differential natural population growth represents 10-50 percent of the trend rate of poverty reduction.




The Economic Consequences of Demographic Change in East Asia


Book Description

Recent studies show that almost all industrial countries have experienced dramatic decreases in both fertility and mortality rates. This situation has led to aging societies with economies that suffer from both a decline in the working population and a rise in fiscal deficits linked to increased government spending. East Asia exemplifies these trends, and this volume offers an in-depth look at how long-term demographic transitions have taken shape there and how they have affected the economy in the region. The Economic Consequences of Demographic Change in East Asia assembles a group of experts to explore such topics as comparative demographic change, population aging, the rising cost of health care, and specific policy concerns in individual countries. The volume provides an overview of economic growth in East Asia as well as more specific studies on Japan, Korea, China, and Hong Kong. Offering important insights into the causes and consequences of this transition, this book will benefit students, researchers, and policy makers focused on East Asia as well as anyone concerned with similar trends elsewhere in the world.




The Impact of Population Growth on Well-being in Developing Countries


Book Description

This book examines the nature and significance of the impact of population growth on the weIl-being of developing countries-in particular, the effects on economic growth, education, health, food supply, housing, poverty, and the environment. In addition, because family planning programmes often significantly affect population growth, the study examines the impacts of family planning on fertility and health, and the human rights implications of family planning programmes. In considering the book's conclusions about the impact of population growth on development, four caveats should be noted. First, the effects of population growth vary from place to place and over time. Thus, blanket statements about overall effects often cannot be made. Where possible, the authors note the contexts in which population effects are strongest and weakest. Second, all of the outcomes examined in this book are influenced by factors other than population growth. Moreover, the impact of population growth may itself vary according to the presence or absence of other factors. This again makes bl anket statements about the effects of population growth difficult. Throughout the chapters, the authors try to identify other relevant factors that influence the outcomes we discuss or that influence the impact of population growth on those outcomes.
