Policymakers worldwide are struggling to adapt their pension systems to the reality of aging populations, globalization, and tightening budgets. The World Bank actively supports these policymakers by helping them to identify the economic and demographic challenges facing them to highlighting potential policy responses and providing implementation support. 'New Ideas about Old Age Security' is a selection of papers presented at a conference in September 1999 convened by the World Bank and attended by leading academics and policymakers from around the world. These papers, which have subsequently been revised, contain a sample of the most recent thinking in the global debate over pension reform. The papers in this volume explore a wide variety of pension reform issues. Some of the topics covered in this book include new approaches to multi-pillar pension reform, the relevance of index funds for pension investment in equities, and managing public pension reserves.
