Credit Constraints, House Prices, and the Impact of Life Cycle Dynamics

How does the life cycle--namely, mortality risk and the expectation at birth of a rising age-profile of income and assets--impact house price dynamics? This paper investigates how equilibrium house prices respond to a tightening in credit constraints under two different but similarly calibrated models: one an infinite-horizon setting and the other a life-cycle environment. The main conclusion is that house price dynamics are magnified by the presence of life cycle features.

Failure to Launch: Housing, Debt Overhang, and the Inflation Option During the Great Recession

Can inflating away nominal mortgage liabilities cure debt overhang and combat a severe housing bust? With a focus on the Great Recession, I address this question using a structural macroeconomic model of illiquid housing, endogenous credit supply, and equilibrium default. First, I show that the model successfully replicates and provides insight into the dynamics of the U.S. economy since 2006. Second, I show that temporarily raising the inflation target would have cut foreclosures by over 60% and led to a more robust recovery in real economic variables.
