内容摘要：

We conduct a field experiment in a typical Chinese prison to examine in- group bias in groups with a stigmatized identity. Inmates are provided with the opportunity to work for a charity. We find evidence of both pro-sociality and in-group favoritism among inmates. They increase effort when their out- put contributes to a charity and work even harder when the beneficiary has prisoner identity. However, inmates who have been in prison for a longer period are less likely to increase their efforts to help a prisoner beneficiary. Such a negative correlation is not observed when the beneficiary is an out- sider. These findings are consistent with our hypothesis and highlight the importance of social interaction in the formation of in-group bias.
