We present a rule-of-thumb consumption model with participation in a ``Save More TomorrowTM'' (SMarT) plan, and we analytically derive the fraction of life-cycle wage increases that must be saved to offset a reduction in social security benefits resulting from an aging population (holding taxes...

Hyperbolic discounting with naiveté is widely believed to provide a better explanation than exponential discounting of why people borrow so much and why they wait so long to save for retirement. We reach a different set of conclusions. We show that if financial planning is enriched to include...

In this paper we propose a new strategy for comparing the behavior of a hyperbolic discounter who possesses self-control problems to an exponential discounter who does not. Our strategy controls for inherent differences in overall levels of impatience across discount functions, which thereby...

We quantify the welfare gains from better retirement planning using a model in which retirement planning is time inconsistent. A modest increase in a household’s planning horizon by just a few years generates large aggregate and individual welfare gains.
