The U.S. housing boom from 2000 to 2006 consisted of two fundamentally different phases. An increase in foreign credit supply (a savings glut) can explain the initial countercyclical run-up in house prices from 2000 through 2002, whereas an increase in domestic credit demand –driven by a relaxation of domestic credit standards– can explain the subsequent procyclical boom phase from 2003 to 2006. A tightening of domestic credit standards can fully explain the bust from 2007 to 2010. I base these conclusions on a quantitative open economy model with housing and collateralized foreign debt. Countercyclical government spending financed by a lump sum tax stabilizes house prices, output and domestic inflation over the entire boom period, pushes the economy away from the zero lower bound, and raises domestic utility.
