Although decision makers are often reported to have difficulties in making comparisons between multi-dimensional decision outcomes, economic theory assumes a uni-dimensional utility measure. This paper reviews evidence from behavioral and brain sciences to assess whether, and for what reasons,...

We propose a novel utility representation for preferences over risky timed outcomes. The weighted temporal utility model generalizes many well known utility functions for intertemporal decision making under risk. A decision maker with a weighted temporal utility function can have time consistent...
