Buffer-stock models of saving are now standard in the consumption literature. This paper builds theoretical foundations for rigorous understanding of the main features of such models, including the existence of a target wealth ratio and the proposition that aggregate consumption growth equals...

The budget constraint requires that, eventually, consumption must adjust fully to any permanent shock to income. Intuition suggests that, knowing this, optimizing agents will fully adjust their spending immediately upon experiencing a permanent shock. However, this paper shows that if consumers...

Using life-history survey data from eleven European countries, we investigate whether childhood conditions, such as socioeconomic status, cognitive abilities and health problems influence portfolio choice and risk attitudes later in life. After controlling for the corresponding conditions in...

This paper presents a simple new method for estimating the size of wealth effects on aggregate consumption. The method exploits the well-documented sluggishness of consumption growth (often interpreted as habits in the asset pricing literature) to distinguish between short-run and long-run...

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....
