We explored the relationship between COVID-19 labor market shocks and the likelihood of hardship withdrawals or plan loans from retirement accounts, which could significantly impact workers' retirement savings. We found that about 14% of working-age respondents took a hardship withdrawal or plan loan. Those reporting a COVID-19 labor market shock had odds of a hardship withdrawal as much as 3.8 times as high as otherwise comparable respondents who did not have a shock. Additionally, we found that the relationship to a COVID-19-related labor shock was moderated by the objective and subjective financial knowledge of individuals, suggesting a potential role for financial education in alleviating retirement risks. A notable finding is that respondents exhibiting financial knowledge overconfidence were more likely to take a plan loan or a hardship withdrawal than those with appropriate levels of confidence or low levels of confidence. This study offers important insights for policymakers, educators, and practitioners.
