Housing supply price elasticities revisited Evidence from international, national, local and company data

This paper re-examines one of the key parameters in housing economics - the price elasticity of housing supply In the international literature there is little agreement on its value or even on the appropriate methodology for its measurement The paper argues that different spatial scales capture different aspects of the problem and therefore there is merit from comparing results at international national local and firm level Using standardised models there is evidence that the responsiveness of housing supply to market conditions is lower in Britain than in the US or Australia However supply is more responsive to the change in house prices than their level With exceptions most past research on supply in Britain concentrates on the national or regional dimensions The paper finds that there are also insights to be obtained from examining local and firm level data Local estimation across the Thames Gateway shows the importance of planning constraints on supply elasticities but historical patterns of land use and geography are also important Firm level data indicate that supply elasticities are greater for large firms than for small firms (C) 2010 Elsevier Inc All rights reserved
