On the user cost and homeownership

Abstract

This paper studies the determinants of housing tenure choice and the differences in the cost of housing services across households in an overlapping generations model with household-specific uninsurable earnings risk and housing prices that vary over time. We model houses as illiquid assets that provide collateral for loans. To analyze the impact of preferential housing taxation on the tenure choice, we consider a tax system that mimics that of the U.S. economy in a stylized way. We find that a mixture of idiosyncratic earnings uncertainty, house price risk, down payments and transaction costs are needed for the model to deliver life cycle patterns of homeownership and portfolio composition similar to those found in the data. Through simulations, we also show that a rental equivalence approach (relative to a user cost approach) overestimates the mean unit cost of housing by approximately 3 percent.
