Abstract: We show that if agents are uncertain about their discount rates it may be rational for them to discount the distant future hyperbolically rather than exponentially. Our findings thus may rationalize a common observation in experimental work, which indicates that people discount the future at hyperbolic rates. We show that under some assumptions, uncertainty over hazard rates may lead to non-constant discounting but not imply dynamically inconsistent behavior. Under other assumptions, uncertainty over discount rates can lead to dynamically inconsistent behavior like violating planned consumption profiles by bringing consumption forward.
