What Drives House Prices in Europe?

Boom-and-bust cycles in the housing market pose a threat to macroeconomic and financial stability, thus calling for a timely assessment of imbalances. This work sheds light on the drivers of house price dynamics in some euro area economies, investigating the risks of overheating. We show that an Error-Correction-Model (ECM) featuring a long-run relationship between house prices and income and short-run effects of interest rates and housing supply fits the data well in most cases. We then propose a novel model-based misalignment indicator and find that extrapolative house price expectations play an important role in the build-up of speculative bubbles.
