Abstract

We study optimal saving when incomes are certain and risk bears on consumption. A key finding is that, with CARA utility and additive uncertain consumption, or CRRA utility and multiplicative consumption, risk-averse individuals do not form precautionary saving as in the standard theory of saving under uncertainty.
