| Title | Groups disguise lying better |
| Author | Yoshitaka Okano and Eiji Goto |
| Abstract | This study experimentally examines the lying behavior of individuals and two-person groups, using a dice-rolling experiment developed by Fischbacher and Follmi-Heusi (2013). We found strong evidence of lying in both individuals and groups,but partial lying (not lying to the maximum extent possible) is more pronounced under group decisions. Furthermore, from the experimental data, we estimated thepreference parameter(s) of existing models for lying aversion. The results reveal thatgroups are more sensitive to the social image concern of not being perceived as a liar and have a lower cost of lying than individuals. |
