Index • Introduction • Description of the demand/supply drivers in housing market in Madrid • Model • Results • Conclusions
Introduction • Between 1997 and 1999, housing prices in Madrid falled in real terms without the existence of any economic crisis. • At the same time than a strong rise in other Spanish areas
Introduction • With positive demand factors: • Strong increase on GDP, • the lowest interest rates in the Spanish history • Enough flow of mortgages • Affordability gains • Strong growth on housing prices in other areas • Reasons for the less dynamism in Madrid housing prices? • Market factors? • Public intervention?
Introduction • Capital of Spain • Mayor city: 6 millions P • 17% of Spanish GDP • Main based on service activities and high quality jobs • Financial center • Decission center for business...
Introduction • Years later, we were ask to develop a research project to explain why Madrid housing prices rise more than in the rest of Spain • In only five years everything changed in Madrid housing market • We are witness of what have happened during the period, • from an static situation to a very dynamic process
Introduction – Methodology followed • 1st. Explore statistics trying to describe what has happened • Different methodologies: Time series, Panel data, GIS, combined. • 2nd. Inside a theoretical framework • Economic intuition to define the hipothesis • 3rd. Contrast the hipothesis • 4th. Need for spatial analysis
Description of drivers evolution • Agreement about the fundamental reasons to explain housing prices last decade • Meen, 2001, Andrew and Meen, 2003, Case and Shiller, 2003, Case, Quigley and Shiller, 2005, • In dense cities... Gibb,and O’Sullivan, 2002, Wheaton, 1998.. • If income and financial growth process do not create restrictions • Demografics? .... Where? • Spatial effects
Description of driver: population mobility (number of arrivals and departures)
Description of driver: population mobility (Spanish and foreigners –all arrivals)
Description of driver: population mobility (Spanish and foreigners –all departures)
Description of drivers evolution • These behaviour show a double shock in basic demand of houses • From foreigners • From increase on internal mobility • Located from 2001 • Increasing the size of the housing market • Along the territory?

Model: aggregate definition • Qvdt = f[A(pop, y,f) t, B(Pvt, tit, trt, cut)] (1) • Qvot = g[Pvt, Cmt, tit, Otrost] (2) • Pvt = G[k(pop, y,f, ht) t, m( tit, trt, cut)] (3) Where: • Qvdt is housing demand, • pop is population, • y, income • f mortgages funds • Pvt, housing prices • tit, interest rate • trt, transactions • cut housing use cost • Qvot Housing supply • Cmt, construction costs • Otrost other components, like land, developers market size, market power, administrative restrictions, housing policy, regional differences
Model: Demand equation (See Andrew and Meen, 2003, DiPascuale and Wheaton, 1996 and many others references) • Phd*t = a1 + a2 (pop)t + a3 (ry)t – a4 (h)t + a5 (w)t – a6 (uc)t + a6 (ff)t +et • Identifying the role of different components of population dynamic • Pop = Dp + IR + OI

Model: demand equation results • Long term components explain the price evolution, • in the general model (all population) • Negative impact of income, finance, changes on population and interest rates (increase on prices, reduces the demand) • Short run impacts of income (2 lags) and changes on population, finance and interest rates (3 lags) • Positive impact on prices from inflation and available stock • Short run effects for stock (4 lags) and inflation (3 lags) • Strong dynamic relationships
Model: demand equation results • Migration models: • Higher sensibility to changes on income • Migration is positive correlated with changes on prices: arrivals stress the prices (both cases, total and foreign) • Total inmigration is positivelly correlated with interest rates but not with existing stock, so, household movements could stress construction outside Madrid • Foreign inmigration is positive correlated with finance and interest rates, and negativelly with housing availability. • These could suggest that their arrival depends of income but also of the existent stock available, purchase capacity and the availability to have finance. • From 2000, banks in Spain start to give mortgages masivelly to inmigrans with permanent job....
Model: demand equation results • Migration models (cont): • Positive correlation among stock and prices in presence of foreign movers suggest that there is a lack on supply for this demand • Negative correlation in the case of all movers (most are previous residents, spanish and foreigners) suggest that they could decide move to other market in the case of good condicions. • This also suggest that higher prices or other factors expulse this demand to other housing markets.
Model: Supply equation • Goodman, 2005, Meen, 2003, Malpezzi y Maclenan, 2000 y Glaeser y Gyourko, 2005 • Qts = f(PH,t, Ct ,Ht-1 , Gtk , pH) = • =ea1 PH,ta2 Cmta3 Csta4 ita5 pta6 Ht-1a6 [hk Gtk ]a7pHe a8 et • Where: • - PH,t housing prices • - Cmt materials costs • - Cst cost of salaries • .- it interest rates • - pt cpi • - Ht-1 existing stock • - hk Gtk regional caracteristics matrix • - pHeinflation expectations in housing • - et random component • a1..8 estimated parameters

Model: Supply Elasticity results • High supply elasticity which suggest rapid reactions of the developers when prices rise • Low capacity of explanation, which suggest that the share of the market performing as a market is small • Also suggest that there are other variables affecting the new supply decissions process, • The existence of supply restrictions in Madrid markets • Lack on supply... Expulse demand • And increase prices in a market segment
