The paper will address the development of housing regimes in the new EU member states,introducing the analytical framework of a housing sector matrix to classifyforms of housing by tenure andintegration mechanism. Thus, ourhousing sector matrixcombines two common approaches: thestructure of housing provision (Ball and Harloe 1992) and the tenure-focused approach (Kemeny 1981, 1995). Starting from this rough typology of housing provisions, we also take further factors that have a major impact on the behaviour of stakeholders/actors into consideration, namely the legal/regulatory environment and the subsidy/tax system, to define the housing regimes. In its analysing of the development of the new member states the paperdifferentiates between global factors (economic development model, countries’ position in global economic structures, etc.) and local factors like the political/power structure, mainstream social ideology, the interplay betweendifferent stakeholders, etc. Institutional analyses (Bengtsson and Ruonavaara 2010) that take path-dependent factors into account are thus best able to address the process by which new housing regimes emerged in post-socialist countries and the degree to which we find convergence/divergence trends. The paper analyses three junctures in the development process after 1990: radical changes after the collapse of the old system; the development of the mortgage market and the regulation of the social sector at the turn of 2000; and reactions to the financial crisis of 2008. The paper concludes that the new member states are following the same trajectory despite their institutional differences.
