A number of OECD countries experienced an environment of low interest rates and a rapid increase in housing market activity during the last decade. Previous work suggests three potential explanations for these events: expansionary monetary policy, capital inflows due to a global savings glut and excessive financial innovation combined with inappropriately lax financial regulation. In this study we examine the effects of these three factors on the housing market. We estimate a panel VAR for a sample of OECD countries and identify monetary policy and capital inflows shocks using sign restrictions. To explore how these effects change with the structure.
