The past decade has brought an increasing recognition to the importance of pension systems to the economic stability of nations and the security of their aging populations. During this time, the World Bank has taken a leading role in addressing this challenge through its support for pension reforms around the world. Old-Age Income Support in the 21st Century attempts to explain current policy thinking and update the World Bank¡¦s perspective on pension reform. The Bank has been involved in pension reforms in nearly 60 countries, and the demand for its support continues to grow. This book incorporates lessons learned from recent Bank experiences and research that have significantly increased knowledge and insight regarding how best to proceed in the future. The book has a comprehensive introduction and two main parts. Part I presents the conceptual underpinnings for the Bank¡¦s thinking on pension systems and reforms, including structure of Bank lending in this area. Part II highlights key design and implementation issues where it signals areas of confidence and areas for further research and experience, and includes a section on regional reform experiences, including Latin American and Europe and Central Asia. This book will be of interest to Bank clients, the international community, and anyone interested in pension systems and reform.
