The Housing Bubble and Retirement Security
House prices rose 60 percent between 2000 and 2007 before the housing bubble burst. The question is whether the housing boom made people better or worse prepared for retirement. Theory says that infinitely-lived households experience no increase in their real net worth when housing prices increase and would therefore have no reason to borrow against the increment in their home equity to increase their consumption. Two pieces of evidence suggest that they did tap their equity: the big increase in mortgage borrowing has accompanied the run-up in house prices, and a number of studies have reported a positive relationship between house prices and consumption. Using the 2004 Survey of Consumer Finances (SCF) this paper investigates the probability of households extracting home equity through an increase in housing-related debt, the probability that they use their housingrelated borrowing for consumption, and finally the factors that determine the level of consumption spending out of their increased debt. The results show that while homeowners appear to take the present discounted value of future rents into account, many of them extracted equity and used it for consumption. A substantial proportion – perhaps 30 percent – of older households will be less secure in retirement because of the housing bubble.
