| Abstract: | This paper studies consumption and savings profiles and security market prices in a permanent income model when consumers are robust decision makers. Robust decision makers and expected utility maximizers share a common probabilistic speculation of the income shocks. But robust decision makers suspect specification errors and want decisions to be insensible to them. The authors show how a preference for robustness lies concealed within the quantity implications of the permanent income model and how it can be revealed by market-based measures of "risk-aversion". |
