The conference was devoted to the socio-economic causes and consequences at both the individual and the societal level of the unprecedented increase in life expectancy over the past few decades. At the micro level, a better understanding is needed regarding the extent to which the increase in human life expectancy has been shaped by individual health behaviour, rather than by other socio-economic influences, and through which channels this happened. Conversely, it is important to understand better how the prolongation of the life cycle will shape individual behaviour. The conference focused on behaviour relating to health, education, and the supply of labour. Although generally perceived as a positive development, the increase in life expectancy also poses policy challenges for social security and the cohesion of society, given that different social groups benefit from rising longevity to varying degrees. Important questions have been raised about the macro consequences of the prolongation of the individual life cycle, not least because having an understanding of the underlying mechanisms will be crucial for assessing the extent to which retirement, health, and educational policies need to be reformed. The recognition that the design of reforms should be guided by an awareness of the potential effects ∗ Michael Kuhn (corresponding author), Wittgenstein Centre (IIASA, VID/OAW,¨ WU), Vienna Institute of Demography, Welthandelsplatz 2, Level 2, 1020 Vienna, Austria Email: [email protected] Alexia Prskawetz, Institute of Statistics and Mathematical Methods in Economics, TU Wien and Wittgenstein Centre (IIASA, VID/OAW,¨ WU), Vienna Institute of Demography, Vienna, Austria Uwe Sunde, Seminar for Population Economics, University of Munich, Munich, Germany DOI: 10.1553/populationyearbook2014s001 2 Health, education, and retirement over the prolonged life cycle of policies on individual life-cycle behaviour closes the circle of topics addressed in this volume. The remainder of this introduction sets the scene for the articles contained within this volume by presenting the editors’ (subjective and selective) take on the state of research regarding the link between longevity and individual life-cycle behaviour relating to health, education, and retirement. 2 Health, health behaviour, and the prolonged life cycle This sub-section presents a brief review of some of the recent debates on the role of health in the extension of the life course. After providing an overview of the debate on the extent to which reductions in mortality are accompanied by reductions in morbidity, we highlight the roles of health behaviours, education and social context in shaping health and longevity. 2.1 The debate on healthy life expectancy: demographic and economic perspectives Since the 1980s there has been a heated debate among demographers and epidemiologists about the relationship between life expectancy and morbidity, and the implications of this relationship for the quality of life experienced by ageing populations. Central to this debate are the following questions: Is increasing life expectancy accompanied by a compression of morbidity, and thus by a more than proportional increase in healthy life expectancy (Fries 1980)? Alternatively, is mortality accompanied by an expansion of morbidity (Gruenberg 1977)? Moreover, is it possible that morbidity and mortality are jointly determined by physiological processes that govern both the incidence and severity of disease (Manton 1982)? This debate is on-going (see, e.g. the survey by Crimmins and Beltran-Sanchez (2010)). While recent studies based on aggregated data provide evidence that healthy life expectancy has been increasing (e.g. Cai and Lubitz 2007), a much
