We study the effect on savings of an increase in the capital risk of the investment opportunities when the representative consumer is allowed to optimally choose her portfolio. Sandmo (1970) and Levhari and Srinivasan (1969) prove that individuals with high risk-aversion and time-separable,...

Was the increase in income inequality in the US due to permanent shocks or merely to an increase in the variance of transitory shocks? The implications for consumption and welfare depend crucially on the answer to this question. We use CEX repeated cross-section data on consumption and income to...

I show that countercyclical earnings dynamics can have quantitatively important effects on saving and portfolio choice decisions over the life cycle. During expansions (recessions) when expected future earnings growth is high (low), households save less (more) and also invest a higher (lower)...

This paper studies the link between rising income uncertainty and household fertility patterns in an Aiyagari-Bewley-Huggett framework augmented to include fertility decisions and infertility risk. Building on Becker and Tomes (1976), I model fertility decisions as sequential, irreversible...

In fifteen European countries, China, and the US, stocks and business equity as a share of total household assets are represented by an increasing and convex function of income/wealth. A parsimonious model fitted to the data shows why background labor-income risk can explain much of this...
