Recent episodes of housing bubbles, which occurred in several economies after the burst of the United States housing market, suggest studying the evolution of housing prices from a global perspective. We utilise a theoretical model for the purposes of this contribution, which identifies the main drivers of housing price appreciation, such as, for example, income, residential investment, financial elements, fiscal policy and demographics. In a second stage of our analysis, we test our theoretical hypothesis by means of a sample of 18 OECD countries from 1970 to 2011. We employ the vector error correction econometric technique in terms of our empirical analysis, which permits us to model the long-run equilibrium relationship and the short-run dynamics, which also helps to account for endogeneity and reverse causality problems.JEL Classifications: C22, R31
IntroductionThe occurrence of several episodes of housing bubbles in a number of developed economies in the second half of the 2000s, suggests the necessity of identifying the main drivers of this market.In order to contribute to the existing debate, we begin by proposing a theoretical explanation of housing prices, which puts forward the role of the basic fundamentals of this market, for example, disposable income, real residential investment, mortgage rates and demographics. Our model also accounts for the behaviour of monetary authorities by including credit standards. Moreover, in our specification there is room for the public sector to perform its role by means of taxation. We then proceed to test the validity of our theoretical model by applying cointegration analysis (Johansen 1995) on a sample of 18 OECD economies during the period 1970-2011. Our econometric results assure the existence of a long-run relationship among the variables and capture the adjustment in the short run by means of a Vector Error Correction Model (VECM). This technique also accounts for endogeneity and reverse causality problems.In terms of economic policy our analysis upgrades the role of the prudential and fiscal policies in relation to monetary policy. Moreover, our results also point to disposable income as the cornerstone of the model.
