Group Decision Making Under Risk: An Experiment with Student Couples

Abstract

In an experiment, we study risk-taking of cohabitating student couples, finding that couples' decisions are closer to risk-neutrality than single partners' decisions. This finding is similar to earlier experiments with randomly assigned groups, corroborating external validity of earlier results.
