- The relationship between household mobility and financial frictions, particularly those associated with negative home equity, has attracted increased attention after the recent boom and bust in the U.S. housing markets.
- With prices falling 30 percent nationally, negative equity expanded greatly across many markets.
- The drop in mortgage rates, along with policy interventions to encourage historically low-rate refinancing, likewise recommend a closer look at mortgage interest rate lock-in effects, which are likely to become important once Federal Reserve interest rate policy normalizes.
- This article updates estimates published in a 2010 study by the authors of the impact of three financial frictions—negative equity, mortgage interest rate lock-in, and property tax lock-in—on household mobility. The addition of 2009 American Housing Survey data to their sample allows the authors to incorporate the effect of more recent house price declines.
- The new study’s findings corroborate the 2010 results: Negative home equity reduces household mobility by 30 percent, and $1,000 of additional mortgage or property tax costs lowers it by 10 to 16 percent.
- The study also explains that reduced homeowner mobility may not have a significant impact on the unemployment rate, yet reduced mobility attributable to financial frictions has economic and social effects beyond its possible implication for labor markets.
- The authors offer directions for future research, such as potential improvements to measures of household mobility.
