Focusing effects and time discounting

Revision requested Review of Economic Studies Working paper Do people prefer concentrated utility? We present novel findings on intertemporal choice that cannot be explained by discounted utility, including hyperbolic discounting. In a series of lab experiments, we let subjects allocate money to earlier and later payoffs. We vary within-subject whether these payoffs are concentrated in a single period or dispersed over multiple periods. Our results show that intertemporal choice is affected by concentration bias: First, individuals allocate less money to later payoffs when these are dispersed than when they are concentrated.
