We study the optimal size of a pay-as-you-go social security program for an economy composed of both permanent-income and hand-to-mouth consumers. While previous work on this topic is framed within a two-period partial equilibrium setup, we study this issue in a life-cycle general equilibrium...

Contrary to the usual presumption that welfare is maximized if consumers behave rationally, we show in a two-period overlapping generations model that there always exists a rule of thumb that can weakly improve upon the lifecycle/permanent-income rule in general equilibrium with irrational...

Contrary to the usual presumption that welfare in markets is maximized if consumers behave rationally, we show in a two-period overlapping generations model that there always exists an irrational consumption rule that can weakly improve upon the lifecycle/permanent-income rule in general...
