Lifetime distribution and redistribution is analysed in this book, in far more detail than has been attempted before. A dynamic cohort microsimulation model is used as an exciting new tool to analyse several questions which have previously been almost impossible to answer. These questions concern income distribution and redistribution, social security and income tax incidence. This book will be of interest to those working in social and economic policy who are concerned about such issues. It will also be of interest to the rapidly growing numbers of researchers and government analysts constructing microsimulation models.
