fixed cost of lying and image concerns not to be perceived as a liar. We show that equilibria naturally arise in which … agents with low costs of lying randomize among a set of the highest potential reports. Such equilibria induce a distribution … the range of reported lies while the effect of the fixed cost of lying is the opposite. …

Extending the die rolling experiment of Fischbacher and Föllmi-Heusi (2013), we compare gender effects with respect to … group decisions. We find more lying in male groups and mixed groups than in female groups. …
