'In this volume economists for the first time come to grips with the substantial impact of demographic uncertainty on the economy and public finances. It contains not only important methodological contributions but also provides fresh insights on how demographic risks can best be shared across generations.' Lans Bovenberg, Director, Netspar, Tilburg University
'Due to population aging, public pensions and health-care systems are under pressure throughout the industrial world and beyond. But this pressure is mostly seen in long-term projections of unsustainability. It is difficult for governments to sell painful reforms such as privatization and delayed retirement in the face of uncertain futures. This timely and important book, edited by a world leader in the field, provides an explicit state-of-the-art evaluation of uncertainty in budget projections.' Ronald Lee, Edward G. and Nancy S. Jordan Endowed Chair in Economics and Professor of Demography and Economics, University of California, Berkeley
