The Relative Price of Housing and Subsequent GDP growth in the USA
The great recession of 2008-9 followed an extraordinary house price bubble. The sluggish was characterized by a very slow recovery of residential investment. Oddly, the extensive revision of macroeconomic models which implied a very low probability of great recessions has not involved a focus on housing. Instead it has focused on financial frictions – essentially it is assumed that the 2008-9 recession was extraordinary because a major financial crisis occurred. Dean Baker dissents (as he often does) arguing that the severity of the recession could have been predicted given the massive decline in housing prices and earlier estimates of the effect of home equity on consumption. This note attempts to being to assess that claim. It also asks if it is possible to forecast GDP growth over the medium term. Finally it is part of the Rip Van Keynes series, because I will use an empirical strategy which has been out of fashion for at least four decades – basically an ad hoc OLS regression (sometimes I even include an exponential trend).
