In accounting for the phenomenon of present bias, the hyperbolic discounting and quasi-hyperbolic discounting models have distinct predictions beyond today. We provide experimental evidence supporting diminishing rate of discounting beyond present period under careful experimental controls. In...

This paper proposes a new, more robust, experiment to test for the presence of hyperbolic discounting. Recently, a growing literature has studied intertemporal choice when individuals discount the future hyperbolically. These preferences generate dynamically inconsistent choices, in contrast...

We study in an online, real-effort experiment how the bracketing of non-binding goals affects performance in a work-leisure self-control problem. We externally induce the goal bracket – daily goals or a weekly goal – and within that bracket let subjects set goals for how much they want to...

Hyperbolic discounting and lack of self-control are different phenomena that share the property of dynamic inconsistency. Despite being different, these two concepts have been extensively conflated and confused in Economics. I review the definitions and properties of both concepts, the...

We examine the confounding between models of intertemporal choice. Critical outputs from hyperbolic, exponential and arithmetic discounting are all highly multicolinear in commonly used research designs. This confounding means that if one model defines a participant as impulsive, they all will:...
