The Institute of Socio-Economic Research of Luxembourg (LISER) has organized on November 12 and 13 the 3rd Affordable Housing Forum that was first organised in Switzerland. On this occasion, the inaugural conference was presented by Dr. Nasarre and dealt with the search for new forms of housing tenure or reformulation of current ones to avoid households’ over-indebtedness and its consequences. Self-construction, collaborative economy and social housing have been topics discussed in the Forum. The forum has had participants and presentations from eleven countries.
