Book excerpt: Population aging is a global phenomenon that influences not only the industrialized countries of Asia and the West, but also many middle- and low- income countries that have experienced rapid fertility decline and achieved long life expectancies. This book explores how workers and consumers are responding to population aging and examines how economic growth, generational equity, trade and international capital flows are influenced by population aging. The contributors draw on the experience of the developing and industrialized worlds and on countries in Asia, North America, and Europe. They offer new evidence about micro-level responses of labor force participation, earnings, and savings to actual and/or perceived demographic change. Their broad perspective on population aging spans the entire demographic transition and demonstrates the importance of effective policy response in the early stages of population aging. Also included are policy analyses that explore the use of tax policy, financial reform, and policies targeting immigration and procreation. This insightful study will prove invaluable to students and scholars of population economics, public sector economics, welfare economics, social economics, and public finance. Pension analysts and government policymakers will find the material of great practical use.
