The significant store of knowledge about publicly regulated pensions for old age has grown even more rapidly in the last decade. This book explores current research in four critical areas for pension policy: the political design of pension institutions; the iron links between fiscal deficits, private savings, and pension reform; how macroeconomic policy should be conducted after large private pension funds have emerged; and lessons on efficient organization of the pension industry, drawn from international comparisons including Australia, Chile, Malaysia, and the United Kingdom. The collection combines original theoretical analysis with empirical evidence. Simulations, case studies, and econometric estimates provide policy makers with information about the options they face, while scholars can draw on this book for refining their own investigations or research.
