Abstract: This study test whether social reference points impact individual risk taking. In a laboratory experiment, decision makers observe the earnings of a peer subject before making a risky choice. We exogenously manipulate the peer earnings across two treatments. We find a signicant treatment effect on risk taking: decision makers vary their risk taking in order to surpass or stay ahead of their peer. Our findings are consistens with a social-comparison-based, reference-dependent preference model that formalizes relative concerns via social loss aversion. Additionally, we relate our findings to the impact of private reference points on risk taking.
