Intertemporal utility was concave for gains and convex for losses, consistent with a hypothesis put forward by Loewenstein and Prelec (1992). Discount rates declined over time but less so than previously observed under the assumption of linear utility. For approximately 40% of our subjects constant discounting provided the best fit. The remaining 60% were most consistent with Harvey's (1986) power discounting. Our data provide little support for the popular quasi-hyperbolic model, which is widely used in economics today. We observed an asymmetry in the discounting of gains and losses that, unlike earlier findings, cannot be explained by a framing effect. %G English %L hal-00537058 %U https://hec.hal.science/hal-00537058 %~ SHS %~ HEC %~ CNRS %~ AO-ECONOMIE
