WebCarroll and Kimball (1996) prove that the consumption function is concave if infinitely-lived risk-averse households have a utility function which exhibits Hyperbolic Absolute Risk Aversion (HARA), face income uncertainty, and are prudent. However, the empirical evidence is inconclusive about the importance of income uncertainty for households. Webfunction, but until now there has been no analytical explanation for the concavity of the consumption function that income uncertainty seemed to induce.
