Buffer-stock behavior emerges if consumers with important income uncertainty are sufficiently impatient. In the traditional model, consumption growth is determined solely by tastes; in contrast, buffer-stock consumers set average consumption growth equal to average labor income growth, regardless of tastes. The model can explain three empirical puzzles: the [1991]; the the 1930's; and the temporal stability of the household age/wealth profile despite the unpredictability of idiosyncratic wealth changes.
