Do Teaser-Rate Adjustable-Rate Mortgages Make Owner-Occupied Housing More Affordable?

In this paper, we estimate the structural parameters of an aggregate housing demand curve and the relationship between ARM teaser rates and house prices using a simultaneous-equation Tobit model. The data come primarily from the Federal Housing Finance Board monthly interest rate survey in May of 1987-1989. The empirical results suggest that teaser ARMs produce significant price distortions in local housing markets. These price distortions ameliorate housing affordability for teaser ARM borrowers and worsen affordability problems for all other homebuyers.
