Contribution dynamics in defined contribution pension plans during the great recession of 2007-2009.

We investigate changes in workers' participation and contributions to defined contribution (DC) plans during the Great Recession of 2007-2009. Using longitudinal information from W-2 tax records matched to a nationally representative sample of respondents from the Survey ofl Income and Program Participation, we find that the recent economic downturn had a considerable impact on workers' participation and contributions to DC plans. Thirty-nine percent of 2007 participants decreased contributions to DC plans by more than 10 percent during the Great Recession. Our findings highlight the interrelationship between the dynamics in DC contributions and earnings changes. Participants experiencing a decrease in earnings of more than 10 percent were not only more likely to stop contributing by 2009 than those with stable earnings (30 percent versus 9 percent), but they also decreased their contributions substantially (-$1,839 versus -$129). The proportion of workers who decreased or stopped contributions during the crisis exceeded the proportion observed prior to it (2005-2007).
