“…One of the key parameters of investigation is housing supply elasticity, the sensitivity to which new housing investment responds to (changes in) existing house prices. While older studies mainly use national-level data over long time periods to draw quantitative conclusions about the price elasticity of housing supply, younger publications focus overwhelmingly on regional or local housing market data; recent contributions include Green et al (2005), Meen (2005, Hwang and Quigley (2006), Goodman and Thibodeau (2008), , Ball et al (2010) and Saiz (2010). The advantage of using local rather than national data in studying housing supply arises from the fact that housing markets are essentially spatially separated, following from the fact that houses are immobile and hence both produced and consumed locally.…”
