Abstract
We investigate whether recently high U.S. house prices are justified by fundamental factors. The standard unit root and cointegration tests with aggregate data indicate that house rent is the only fundamental which has the same order of integration as the price, but these two variables are not cointegrated. Nationwide analysis potentially suffers from problems of the low power of stationarity tests applied to relatively short series and the ignorance of dependence among regional house markets. Therefore, we conduct panel data stationarity tests which are robust to cross-sectional dependence and have greater power than univariate tests. While this time it is inflation and income that have the same order of integration as house price, they are not cointegrated with it, even if combined with the aggregate stock index. It appears that the real estate prices take long swings from their fundamental value and it can take decades before they revert to it.
