Today's dominant strain of macroeconomic models supposes that aggregate consumption can be understood by assuming the existence of a 'representative agent' whose behavior rationalizes observed outcomes.

This paper considers several alternative explanations for the fact that households with higher levels of lifetime income ( the rich') have higher lifetime saving rates (Dynan, Skinner, and Zeldes (1996); Lillard and Karoly (1997)). The paper argues that the saving behavior of the richest...

We argue that the US personal saving rate's long stability (1960s-1980s), subsequent steady decline (1980s-2007), and recent substantial rise (2008-2011) can be interpreted using a parsimonious buffer stock model of consumption in the presence of labor income uncertainty and credit constraints....
