Housing co-operatives today no longer serve lower-middle income households, but rather the upper-middle groups (Wfclawowicz, 2002). Poland could learn from a number of OECD countries that have tried to enhance the housing supply through nonprofit organisations. Whereas various measures have been introduced by governments to support non-profit organisations, policy practices indicate the importance of improving the financial arrangements with them (Box 2.13). They include for instance providing matching funds, increasing non-profit organisations’ access to capital markets and setting aside a share of national housing grants for non-profit developers (OECD, 2010a).
