This book addresses issues of defining and measuring the quality of life. Recent developments in the philosophical definition of well-being are discussed and linked to practical issues such as the delivery of health care, and the assessment of women's quality of life. Leading philosophers and economists have contributed to this volume to consider the problems the subject raises. This volume reflects the growing need for interdisciplinary work as economists become more sensitive to the importance of facing fundamental philosophical questions and of the importance of linking their theoretical enquiries to an understanding of complex practical problems.
