Population ageing pensions and growth : intertemporal trade offs and consumption planning This highly topical book explores key issues in evaluating the long run implications of population ageing for pensions taxation intergenerational equity and social welfare. Societies face long term phenomena such as demographic change and climate change that impose costs and benefits far into the future. These present challenges for policymakers in planning intertemporal consumption paths that balance the goals of efficiency and equity. An exploration of these issues with respect to population ageing in particular is the primary motivation for this book. John Creedy and Ross Guest evaluate these problems with a particular focus on the role of concepts assumptions and value judgements. This book will be a fascinating read for researchers interested in the social evaluation of population ageing and climate change. Public policy makers and advisers will find the analysis of practical policy questions such as alternative regimes for taxing public pensions of special interest. Graduate students of macroeconomics and public economics will also find helpful discussions of social discounting the efficiency and equity effects of tax smoothing and potential new effects of population ageing on labour productivity
