An increase in a married woman's attachment to the labor market affected her family's ability to smooth unexpected income shocks. Between 1970 and 1990, the sharp rise in labor market attachment provided an increasingly important channel for smoothing shocks to spousal income. As the participation rate stabilized, this contribution to smoothing evened out. In the Great Recession, both spouses received negative income shocks, and access to transfer income became the main insurance mechanism. Volatility of consumption followed volatility of family income trends but at a lower magnitude. Families' ability to weather income shocks didn't change during the 1970-2010 period.

We use the 1979 National Longitudinal Survey of Youth to revisit what is termed the credit card debt puzzle: why consumers simultaneously co-hold high-interest credit card debt and low-interest assets that could be used to pay down this debt. Relative to individuals with no credit card debt but positive liquid assets, borrower-savers have very different perceptions of future credit access risk and use credit cards for precautionary motives. Moreover, changing perceptions about credit access risk are essential for predicting transitions among the two groups. Preferences and the composition of financial portfolios also play a role in these transitions.
