Book excerpt: Available online: https://pub.norden.org/nord2021-022/ This issue of Nordic Economic Policy Review is devoted to Nordic housing markets and housing policies. Nordic housing markets face more or less the same problems and challenges, but the way policies and regulations deal with them differs in many respects. A comparison of policies, regulations and results across countries yields valuable lessons for policymakers. The work has been led and edited by Professor emeritus Harry Flam and Professor emeritus Peter Englund.
