内容介绍：

    This paper is to explore how social comparison influences order decisions in newsvendor settings. Firstly, we analyze the order decisions of subjects in settings without social comparison and find that instead of chasing demand, subjects tend to chase prior quantities, that is, subjects adjust their order quantities towards prior order quantities, basing on the prior realized demand. Besides, the order decisions of subjects are pulled to the mean of demand distributions, and the order decisions of male subjects are closer to the corresponding optimal order decisions and fluctuate less than those of female subjects. Secondly, we conduct comparison on order quantities across subjects with same gender and different gender. The results demonstrate that comparison mitigates subjects’ decision bias, which is more significant when the comparison is across subjects with different gender.
