A new working paper (full version here) by Alan L. Gustman, Thomas L. Steinmeier, and Nahid Tabatabai examines the impact the Great Recession has had on the wealth and income of Baby Boomers nearing retirement. It finds, somewhat surprisingly, that their aggregate wealth decreased very little over the past few years:
The retirement wealth held by those ages 53 to 58 before the onset of the recession in 2006 declined by a relatively modest 2.8 percentage points by 2010. ... Very few in the population nearing retirement age have experienced multiple adverse events. Although most of the loss in wealth is due to a fall in the net value of housing, because very few in this cohort have found their housing wealth under water, and housing is the one asset this cohort is not likely to cash in for another decade or two, there is time for their losses in housing wealth to recover.
