This book explores the relationship between the characteristics of the welfare state and the characteristics of the housing system (housing policies, housing outcomes and housing market developments) in different European countries. It consists of a theoretical framework, six published articles and a concluding chapter. All six articles use the welfare state regime theory and typology of Esping-Andersen, the housing system typology of Kemeny or both, or at least some aspects of these, as an explanatory framework. The results of the investigations indicate that there are considerable difference.
