“…Such behaviour actually generates asymmetric responses across the housing market with elastic responses of house building during the former and inelastic ones in the latter (Glaesser, Gyourko & Sacks, 2005). In addition, the slope of the new supply curve changes over time (Pryce, 1999;Bramley, 1993;Malpezzi & Vandel, 2002;Goodman, 2005) and price-supply elasticities vary in the short run (small) relative to the long term (large) (De Leeuw & Ekanem, 1971;Olsen, 1987;Hanushek & Quigley, 1979;Meen, 2002;Blackley, 1999;Glaeser et al, 2005, Quigley, 1997, Topel & Rosen, 1988Malpezzi & MacLennan, 2001;Dipasquale & Wheaton, 1994;Goodman, 2005;Malpezzi & Vandell, 2002).The supply function is local and specific to different regions and metropolitan areas with elasticities changing at a spatial level as a result of the impact caused by territorial factors such as climate (Fergus, 1999) or spatial location (Goodman & Thibodeau, 1998, Saiz, 2007. Land control and zoning affects limit housing supply both directly and indirectly (Quigley et al, 2008;Gyourko, Saiz & Summers, 2008;Barker, 2003) as well as the externalities in housing markets and the resulting regulations or housing policy effects (Murray, 1999;Malpezzi & Vandel, 2002;Whitehead, 2003).…”
