The fundamental role of individual ageing is something that everyone is necessarily aware of, and the division of the life cycle into a number of distinct stages has been recognised for many centuries.This volume collects 32 articles concerned with a variety of economic aspects of individual and population ageing. They have been arranged under four main headings as follows: individual ageing and the life cycle; population ageing; ageing and social insurance; and macroeconomic effects. The editor has prepared a fresh introduction to accompany the piece which aims to set the context and discuss some of the major issues.
