Literature • Linneman and Wachter (1989) • Mortgage market innovations (e.g. ARMs) reduce borrowing constraints, reducing barriers to homeownership • Mian and Sufi (2008) • Rapid increase in supply of credit to areas with high latent demand for mortgages was primary cause of house price boom • Lamont and Stein (1999) • In cities with large fraction of highly leveraged (e.g. high LTV) households, house prices are more sensitive to income shocks
Expectations • Households in MSAs with low housing affordability will be more sensitive to changes in income, availability of mortgages • House prices will be more sensitive to these demand shocks
Housing Affordability • By design, a larger number for NAHB’s Housing Opportunity Index (HOI) represents a high availability of affordable housing • Define: Constrained = 1 – HOI • An increase in Constrained represents a larger percentage of homes sold that can’t be afforded by family with median income and the “typical” mortgage
Measuring Mortgage LendingActivity • Alternative measures of ΔLending variable: • Volume of single-family, purchase-only mortgages originated • Measured by number of loans: NumLoans • Measured by real dollar volume of loans: VolLoans • Share of originated mortgages sold to non-governmental agency investors: NGShare • All three calculated from HMDA data
Basic Regression • Panel data (N=26; T=9) estimated with fixed effects • Regression specification: with three possible measures of ΔLending: ΔNumLoan, ΔVolLoan, orΔNGShare
Empirical Results Notes: Robust standard errors in parentheses; Adjusted R2 is 0.69, 0.71, 0.72, respectively.
Next Steps • Improve current regression setup • Should “constrained”/affordability measure be a dummy variable? • Alternative measure of mortgage market activity: % of mortgage originations that are high APR • Incorporate land share information from Davis and Palumbo (2008) • MSAs with high land share are likely to experience more house price volatility in response to demand shocks
