'The appropriate collection of published studies in Part II and III make the book interesting for a broader audience by providing an overall view on the possible applications of the model...At the same time, the in-depth analysis in individual chapters is interesting for economists and social scientists working in the field of tax and benefit policies....this book is interesting for the broader community and should be read by the experts of tax-benefit policies' The Journal of Artificial Societies and Social Simulation 'The authors are to be congratulated on a most useful book, but even more on the model-building and research projects which it's all about.'
