7. OTB Research Institute House Price, Quality and Economic Growth, ERES 2010 7 of 19 Theory 1.Permanent income hypothesis suggests that aggregate consumption for housing is a stable function of the average income. 2.Over a long period, economic growth will push up incomes and house prices and increase demand for better quality. 3.Quality demand is not constant but influenced by economic growth. 4.There is a long-run development fed by fundamentals as incomes and short-run developments fed by economic growth.

15. OTB Research Institute House Price, Quality and Economic Growth, ERES 2010 15 of 19 Preferred quality and stage of economic growth Differences between low, middle and high growth phases are small (table 2). However, during the recovery people seeking on the outskirts of cities and are more active on the housing market.

16. OTB Research Institute House Price, Quality and Economic Growth, ERES 2010 16 of 19 Multinomial logistic regression: The preferred quality and stage of economic growth The stronger the economy becomes, the more the chances increase of housing demand based on better quality of the home and its environment. In a stagnant economy, the emphasis in demand is on affordability rather than better quality. Odd ratios

19. OTB Research Institute House Price, Quality and Economic Growth, ERES 2010 19 of 19 Conclusions 1.High-growth economy => better-quality property => prepared to pay for it. 2.Stagnant economy => demand for quality second place to the demand for affordable homes. 3.There is a mechanism that trades off quality against affordability. 4.Chance that households in a medium- and high-growth phase will demand more quality than in a low-growth phase. 5.It appears that appreciation of quality varies, particularly between the low-growth phase and the medium-growth phase. 6.The price-quality relationship barely varies between the medium- growth and high-growth phases.
