摘要：
In the past decade, the Chinese government has sought to decrease air pollution through efforts such as the Clean Winter Heating Policy (CWHP) implemented in northern China. We use the heating project as a quasi-natural experiment to study how participation in the project impacts villagers pro(anti) social behaviors. Our results show that treatment villagers are more likely to take illegal straw burning actions and exhibit less prosocial behavior in both incentivized dictator game and public goods games. We further explore treatment heterogeneities and find that two channels are likely to lead to such unexpected consequences. First, CWHP was perceived as a negative income shock. Therefore, the villagers would want to cut down expenditures on straw disposal and become not as generous in the incentivized games. Second, CWHP could lead to lower happiness and satisfaction and directly affect social preference. Additional evidence suggests that the more antisocial and less prosocial behaviors could have been avoided because the project participants are likely to overestimate of their heating costs and underestimate the benefits such as lower indoor pollution.
