The effect of future income uncertainty in savings decision


  • Gomes, Fábio Augusto Reis


This paper analyzes consumption and savings decisions in a two-period consumption setting, supposing that future income is uncertain in the sense of Knight (Knight, F., 1921. Risk, uncertainty, and profit (Boston: Houghton Mi2in)). The results imply that uncertainty averse agents save more than risk averse agents.
